The World’s Tiniest Coffee Is So Stinking Cute (Video)

category:

By Cooking Panda

When the Finnish coffee and cocoa company, Paulig, approached artist and designer Lucas Zanotto and asked him to make a cup of coffee out of one, measly little coffee bean, he did what any caffeine fan would do; found a teensy tiny little coffee mug and got to work (video below).

First, Zanotto grinds the miniature bean up using an emery board.

Then, he sets fire to a tealight candle, and allows the small amount of heat to boil just a smidge of water.

Finally, he just pours the water over the coffee filter, and voila — the tiniest cup of coffee (and probably the most adorable cup of coffee I’ve ever seen) comes together.

Something about watching this video is ridiculously soothing; I don’t know if its the monochromatic theme Zanotto employs (primarily calming shades of white), or the cute and tinkling music, but I almost want to start every day off just watching him make this cup of coffee rather than drinking my usual cup, which seems gigantic in comparison.

Of course, some YouTubers couldn’t help but joke around.

“Can you make it decaf?” one commenter wrote. “I’m worried i can’t sleep tonight after this.”

Added another:

“Thank you for making this video; now I know how to write down how fairies make their coffee in a story.”

And lastly, one commenter had an idea for what to do with the tiny cup of coffee.

“Serve it for Trump,” a YouTuber wrote, “Just to make his hands look big.”

What do you think of the video, and how would you enjoy this one-bean cup of coffee?

Turns Out, You Can Actually Drink A Lot Of Coffee

category:

By Cooking Panda

Good news! Your body can handle more caffeine than you thought. If the only thing holding you back from having another cup of delicious coffee is the caffeine content, this study is for you.

According to a new study from the Food and Chemical Toxicology journal shows that adults can safely consume 400 milligrams of caffeine per day. The study reviewed 15 years of data on adverse effects of caffeine on cardiovascular and bone health, and behavior and development. The study conducted the review on healthy adults, pregnant women, adolescents and children.

The finding for the pregnant group showed that pregnant women can consume less than or equal to 300 milligrams of caffeine per day. Children and adolescents can have less than or equal to 2.5 milligrams per kilograms of body weight per day. This information is news to many in the pregnant community, who are usually told that they should stay away from caffeine almost completely.

If you’re among the healthy adult population who just loves your coffee, you probably want to know how much coffee 400 milligrams is. If we’re talking about regular drip coffee, we’re talking about four 8-ounce cups of coffee per day, according to Delish.

A 2012 study by the FDA, however, had different findings. That study recommended that adults keep their caffeine consumption at or under 300 milligrams (or about three cups of coffee) per day. Either way, coffee is believed to have certain health benefits for those of us who do want to drink it. Some of those benefits include reversing liver damage from alcohol consumption, lowering depression, preventing breast cancer and even helping to protect against type 2 diabetes.

So, whether you like to enjoy three cups of coffee each day or four, you are likely safe in your consumption, and also picking up on some of these important health perks. If you’re reading this and thinking “wow, I can only handle one or two cups per day,” I’m with you. Four cups of coffee means about 48 straight hours of jitters for me, but to each his own. At least now you know your scientific limit!

Would You Try This New, Clear, Non-Staining Coffee?

category:

By Cooking Panda

What do you love most about coffee?

Is it the strong taste? The effect of caffeine coursing through your body, helping you to greet the day with more energy? The smell of the beans as they’re roasting?

Or is it the dark brown color of it?

Probably not — yet I’m so used to associating coffee with various shades of brown that the idea of a crystal clear cup of joe feels strange and unusual to me. However, that’s just what David Nagy and his brother Adam created for their company CLR CFF.

The two brothers were tired of their teeth getting stained, but also couldn’t fathom giving up coffee. Thus, CLR CFF was born.

“We are heavy coffee drinkers. Like many other people we struggled with the teeth stains caused by it. There was nothing on the market that would suit our needs so we decided to create our own recipe,” Nagy told Standard.

“Because of the hectic lifestyle we lead we wanted to make a refreshing ready-to-drink coffee which provides the boost but is low in calories.

“The production method is based on physical processing and doesn’t include any chemicals.”

Basically, the brothers spent three months experimenting with their physical processing and freshly roasted Arabica beans to perfect the formula for their clear coffee, which is also extra healthy for you because it doesn’t contain any preservatives, stabilizers or sweeteners.

There are also only four calories per every 6.8 fluid ounces of Clear Coffee, and at the moment, you can buy either a 2-pack or a 5-pack of the drink on the company’s website here, with free shipping within the U.K. if you purchase the 5-pack.

How essential is it for you for your coffee’s color to actually resemble the beans it was brewed with in their original, brown form? Or are you all about this new, clear coffee that won’t stain your teeth ever again?

Try A Cup Of The World’s Most Caffeinated Coffee

category:

By Cooking Panda

First of all, why would you want to drink this much caffeine? If regular coffee doesn’t do it for you anymore, you probably need to rethink your strategy anyway, not increase the intake!

Grubstreet reports that Black Insomnia Coffee (it’s all in the name, isn’t it?) debuted in South Africa, and then officially made its way over to the U.S. This coffee reportedly harbors 300 percent more caffeine than your regular, everyday cup of coffee. The company has lab evidence to back that claim that this is, in fact, the world’s strongest coffee.

The coffee features 702 milligrams of caffeine per 12 fluid ounces of coffee, and I’m wondering when “enough” becomes too much? Surely this can’t be safe for your heart …

Black Insomnia Coffee is sourced through South African robusta beans, and the 16-ounce bags are available to us in the U.S. thanks to Amazon. With a whopping 17.5 grams of caffeine per kilogram of coffee, I guess it’s time for Death Wish coffee (13.2 grams of caffeine per kilogram) and WodFee (13.8 grams) to move over and make room for the new king of coffees. To put this in perspective, a Starbucks dark roast comes in at about 5 to 6 grams of caffeine per kilogram of coffee. Does that paint a better picture? 

According to the Black Insomnia Coffee website, the highly caffeinated (understatement of the year) beverage doesn’t come with any additives, and it has achieved the “World’s Strongest Coffee” title without a burnt taste or high acidic flavor. It’s said to actually have a “nice walnut and almost sweet taste profile.” I guess that means that if you’re in desperate need of a caffeine overload, at least it will taste good.

The brand originally tried to capture an even higher level of caffeine in its coffee, but anything higher than 702 milligrams per 12 fluid ounces is apparently dangerous for consumption. Other brands on Amazon are vying for the top spot, but Black Insomnia seems pretty confident that no one can beat them. Basically, Black Insomnia knows that no other brand can “attempt to surpass this content in the interest of public health and safety.” That’s reassuring …

This Company Wants To Shroom Up Your Morning Coffee

category:

By Cooking Panda

Not much is certain in this day and age — except, perhaps, for our enduring love for and reliance on caffeine.

Coffee is ever-changing, ever-evolving and an ever-important part of our morning routine, so we’re always interested to hear about the newest iteration of our favorite breakfast beverage.

These days, the latest trend in coffee that is all set to change it as we know it (yeah, right) is … medicinal mushroom coffee.

Four Sigmatic is a Finnish startup that purports to be the “Mushroom Coffee Revolution.”

Look, ya’ll: I know it’s not the revolution we need. But until we get active, it might just be the revolution we deserve.

Essentially, the company infuses a coffee mix with medicinal shrooms — not the kind that make you hallucinate and see the world in vivid colors, however. We’re talking the kind to heal you from the inside-out, and actually counteract the effects of caffeine that we don’t necessarily want.

For instance, we all love the jolt of energy and clarity we receive after having our morning cup, but we don’t really want the anxiety, the reliance and the crash. Four Sigmatic asserts that the chaga mushrooms and lion’s mane mushrooms they use not only taste just like a smooth black coffee, but also help prevent stomach acid burn and caffeine crashes.

Count us in, fam!

“The high amounts of minerals in chaga mushrooms can help make the coffee less acidic. Mushrooms like lion’s mane on the other hand offer very interesting potential brain-related benefits. Mushrooms are among the most studied foods in the world and all of these mushrooms have plenty of research on them,” Tero Isokauppila, founder of Four Sigmatic, told Munchies.

Obviously, there are so many different kinds of miracle-coffee brews out there, that every new iteration of coffee should probably be approached with excitement, yes, but also a healthy dose of skepticism. If you really want to avoid a caffeine crash, you probably just need to cut down on caffeine, or switch over to green tea.

If you’re not really that worried about the adverse effects of coffee, though, trying out this mushroom coffee could be kind of fun. What do you think?

A Daily Dose Of Caffeine Is Actually Good For You

category:

By Cooking Panda

Let’s be real, ya’ll — any news that encourages us to continue on with our caffeine habits sounds like good news to us.

In the latest amazing study carried out by scientists over at Stanford University School of Medicine, it appears that there may actually exist a connection between caffeine intake and a healthier, longer life. That means you shouldn’t feel guilty for indulging in a caffeinated cup or two of your drink of choice in the morning, which makes us very, very happy.

“More than 90 percent of all noncommunicable diseases of aging are associated with chronic inflammation,” the study’s lead author, David Furman, PhD, and a consulting associate professor at the Stanford Institute for Immunity, Transplantation and Infection, said in the study. “It’s also well-known that caffeine intake is associated with longevity … Many studies have shown this association. We’ve found a possible reason for why this may be so.”

Basically, the study investigated why people who drink caffeine seem to live longer than those who abstain from caffeine entirely. While too much caffeine still seems to take a negative toll on consumers’ health, the study shows that the correct amount of caffeine intake can actually reduce inflammation in people by blocking chemicals in the blood.

Why does this matter? Well, because, as Furman explained, those 90 percent of all noncommunicable diseases associated with chronic inflammation are noted as being linked to an assortment of different cancers, depression, and even dementia and so on.

By the way, the caffeine in question isn’t just caffeine from coffee — the study showed that the results were consistent for all caffeinated beverages, such as sodas, teas, and other fizzy drinks with a healthy dose of caffeine.

“That something many people drink — and actually like to drink — might have a direct benefit came as a surprise to us,” Mark Davis, PhD, co-senior author, said in the study. “We didn’t give some of the mice coffee and the others decaf. What we’ve shown is a correlation between caffeine consumption and longevity. And we’ve shown more rigorously, in laboratory tests, a very plausible mechanism for why this might be so.”

Reign Supreme With This 24-Karat Gold Royal Coffee Pot

category:

By Cooking Panda

Oh you fancy, huh?

For many of us, the day hasn’t officially begun until we’ve had at least one soothing cup of a caffeinated drink in the morning. It doesn’t matter what form it comes in — usually the stronger the better, in our opinion. But cheap or expensive coffee beans do the trick to take us from zombies to working humans within the span of several minutes.

No, the form of the coffee doesn’t matter — but the container in which it is brewed might, if you’re interested in purchasing this 24-karat gold, custom-made coffee pot.

No joke, ya’ll. This is for real.

Brought to us by Royal Paris, only eight hand-crafted Royal Coffee Makers are assembled each month, with every one requiring more than 50 hours of meticulous labor by skilled artisans. This fancy machine is considered “the world’s first-ever bespoke coffee maker.”

What makes a coffee maker bespoke, you ask? The Royal Coffee Maker invites you to the world of bespoke on its website, and claims:

“From the moment you commission your Royal, a story unfolds. The collaboration between metallurgists, designers, engineers and glass makers affords us the luxury of bringing together only the finest materials to produce a truly unique artwork.”

Your coffee maker can be fashioned out of either 24-karat gold, copper or silver and set on a base made from malachite, azurite or obsidian. It comes with a Baccarat crystal carafe and burner vase and also the option to be engraved with your initials, or perhaps even your family crest, by the way.

Did any of those words make sense to you? Are we the only ones frantically Googling all of the different expensive materials that comprise this coffee pot? 

The Royal will run you somewhere between $10,000 and $18,000, depending on which of the above materials you choose for your pot, but at least you can brag to all of your friends that your gadget is the handiwork of a French artist named Jean-Luc Rieutort and his handy-dandy crew of metallurgists, engineers and sculptors.

What do you think? Will you be treating yourself to this coffee pot for a New Year’s gift?

If You Want To Get The Most Out Of Your Coffee, Don’t Drink It First Thing In The Morning

category:

By Cooking Panda

Many people claim that for them, the day hasn’t really started until they’ve had their first cup of coffee in the morning.

Something about taking that first sip of caffeine just feels right; suddenly, your senses are heightened, your brain is more alert, and you can muster up just enough motivation to get going.

However, research presented by Ph.D candidate Steven Miller at the Uniformed Services University of the Health Sciences in Bethesda, Maryland, suggests that your treasured morning-coffee-caffeine boost is actually just a myth.

Per Metro, Miller explains that the human body is on something called the circadian clock: the body’s 24-hour hormone cycle, and is generally regulated by sunlight.

At around 8 or 9 a.m., the day’s first dose of cortisol — a stress-related hormone that makes us feel alert, similar to caffeine — is released; then again between noon and 1 p.m., and then once more between 5:30 and 6:30 p.m.

That means if you’re sipping on a cup of coffee at around that time, the stimulation of the caffeine is diminished, since cortisol is already pumping through your system.

If you want to really maximize the effects of caffeine, Metro suggests imbibing your chosen drink between 9:30 and 11:30 a.m. or between 1:30 and 5 p.m.

Say It Ain’t So! Coffee Could Go Extinct By 2080 Due To Climate Change

category:

By Cooking Panda

You might want to sit down for this one.

If a new report from The Climate Institute is to be believed, there is an actual, real-life possibility that coffee could be going extinct, folks.

Cue panic mode.

The Climate Institute has issued a dire prediction that rising temperatures are set to wreck the farmland that is used to produce coffee, rendering it incapable of growing coffee beans.

This isn’t slow-going, either — per Metro, the report suggests that half of the world’s coffee farming land will be unsuitable for producing coffee by 2050, and growing levels of fungi and pests are only contributing factors to this inevitable fate.

By 2080, many coffee varieties — Arabica, anyone? — could be entirely extinct.

Think of your children. Think of your children’s children!

“Over 2.25 billion cups of coffee are consumed around the world every day, with nearly half of Australians drinking coffee regularly,” said Climate Institute CEO John Connor in a press release. “Yet coffee is just one of a multitude of things increasingly subject to negative climate impacts, and its negative flow-on effects.”

“Without strong climate action, the areas suitable for growing coffee could halve in a few decades,” Connor added, “pushing production upslope, away from the equator and into conflict with other land uses, such as nature conservation and forestry. By 2080 wild coffee, an important genetic resource for farmers, could be extinct.”

Luckily, not all hope is lost — or, at the very least, Connor suggests that anybody who values coffee (and dreads that caffeine-headache) ought to do their part to get to carbon neutral.

“There are things we coffee drinkers can do to assist,” said Connor. “The first step is to learn about these issues and the steps being taken by Fairtrade and others; the second is to take real action by choosing to buy only the brands that are carbon or climate neutral, provide a fair return to farmers and their communities while helping to build their capacity to adapt to climate change; third is to demand climate action from the coffee companies and our governments to ensure all products, business models and economies are carbon or climate neutral.”

This Coffee Promises To Keep You Awake For Days, But Be Careful Drinking It

category:

By Cooking Panda

Are you addicted to coffee?

Yeah, that makes two of us.

If you’re one of those people who knows that coffee makes the world go round, and you always complain that your brew is just simply not strong enough to get you through the day — in other words, if you are a student — you’ll be interested to learn that there IS stronger coffee out there that will absolutely propel you through that all-nighter. Probably even longer. Maybe indefinitely. Maybe if you drink this coffee, you’ll never sleep again. It’s very possible. Consider:

This is the aptly-named “Ass Kicker” coffee from Australia’s Viscous Coffee shop, according to Elite Daily. Sure, it probably sounds like the others that don’t live up to the hype, right?

Wrong! One cup of this coffee has half the amount of a lethal dose of caffeine (70 cups of coffee could kill you). Yeah. You might die if you order a double.

Ass Kicker iced coffee has 80 times more caffeine than a shot of espresso and 50 times more than a regular drip coffee cup — possibly enough to make you experience mania and hallucinations.

The people behind the half-lethal brew recommend that you take your time with it — it should take around four hours, or else you might have serious trouble. We hear it tastes super delicious and is really tough not to gulp right down.

“I talk to them first, make sure they understand what they are doing, and people often think I’m trying to talk them out of it,” Viscous Coffee owner Steve Benington told Adalaide Now.

You’ll likely be wired for 12-18 hours.

What is even the point of this, you might ask?

Well, it started off with an actual purpose: Benington, who frequently serves up “custom caffeine levels,” concocted the drink for an ER nurse working a night shift. It took her two days to finish her cup, and she stayed awake for three days straight. After that, Benington “toned it down a little” and released the Ass Kicker.

“Some people love it and some are broken by it but it’s all in the name of fun,” said Benington, who makes the drink with four espresso shots, four 48-hour brewed cold drip ice cubes (each has just over two shots of espresso-worth of caffeine) and half a cup of 10-day brewed coffee, finished off with four more 48-hour brewed cubes.

Guess What? Starbucks Can Add As Much Ice As It Wants To Your Drink, Whether You Like It Or Not

category:

By Cooking Panda

People will do anything to ensure they get the caffeine fix they deserve — even if that means filing a lawsuit against mega-chain Starbucks for deceiving them by filling their cups with too much ice and not enough coffee.

According to U.S. district judge Percy Anderson, however, if you order a cold drink, you are gambling with how much ice will be put into your cup. In other words: Starbucks wins. Get over it.

Last June, a California man named Alexander Forouzesh filed a proposed class action suit against Starbucks, alleging that folks consuming cold-beverages from the chain were receiving less liquid than Starbucks advertised.

“If children have figured out that including ice in a cold beverage decreases the amount of liquid they will receive, the Court has no difficulty concluding that a reasonable consumer would not be deceived into thinking that when they order an iced tea, that the drink they receive will include both ice and tea and that for a given size cup, some portion of the drink will be ice rather than whatever liquid beverage the consumer ordered,” Anderson wrote in his decision to strike down Forouzesh’s lawsuit, according to the Guardian.

Starbucks itself had already given customers a little pro-tip on how to get their cold beverages just the way they like, tweeting in 2015:

Customers have always been welcome to request light ice (or, on the other end of the spectrum, extra ice) when placing their order.

Science Says: A Latte A Day Keeps The Heart Attack Away

category:

By Cooking Panda

Oh, go on: Have that extra shot of espresso in your morning coffee today, champ. You’ve earned it.

A York University study tracked 3,721 heart-attack survivors in the U.K. Findings demonstrated that heart-attack patients who drink one to two cups of coffee per day are 20 percent less likely to die prematurely from heart damage than patients who abstain from coffee completely, according to Fox News.

Excuse me while I pour my second cup — for my health.

Once you have a heart attack, you are at much higher risk for another one, or at least for developing heart failure in the future, so practicing heart-healthy habits is crucial for survivors.

Here are ten lifestyle tips for preventing heart attacks and heart disease, courtesy of Web MD:

  1. Eat well. That means lots of fruits, vegetables, grains, and foods high in omega-3 fatty acids (think salmon or fresh tuna). Cutting down on salt, saturated fats, excess sugar and red meats doesn’t hurt, either.
  2. Destress. Prioritize your mental health and take active measures to treat yourself gently. Stressful emotions (such as hostility, rage, and prolonged irritation) could lead to heart attack risk.
  3. Quit smoking
  4. Track your blood sugar. Too much sugar could cause damage to your arteries.
  5. And your blood pressure. High blood pressure means a higher risk of heart attack and disease. Diet, exercise and stress management help keep this under control.
  6. Also your cholesterol intake.
  7. Try to stay within a healthy weight range
  8. Ask your doctor if aspirin is right for you. For some people, a daily low-dose aspirin helps reduce the risk of heart attack.
  9. Exercise. Go, go, go!
  10. Communicate. You’re not an island. Research shows people with wide social networks are less prone to heart trouble, so rely on the people around you.

If You Drink Coffee After A Night Of Loud Music, We’ve Got Bad News For You

category:

By Cooking Panda

Instead of enjoying a hot cup of coffee the morning after a party or concert, maybe we should opt for juice instead. According to research published in the Journal of the American Medical Association, caffeine may have a negative effect on noise-induced hearing loss. 

Caffeine is the most commonly used psychoactive substance, according to the Research Institute of the McGill University Health Centre (RI-MUHC). In the Western world, about 80 percent of adults consumed enough caffeine for it to noticeably affect the brain. The maximum recommended amount of caffeine, which is consumed in coffee, tea, energy drinks, soft drinks, and even medical treatments, is 3 mg/kg a day, equivalent to three cups of brewed coffee.

As excessive noise plays a role in many workplace environments, and as caffeine intake is very common in such environments, Dr. Faisal Zawawi, an Otolaryngologist at the Auditory Sciences Laboratory of the RI-MUHC, believes that the potential link between caffeine and hearing loss is worthy of investigation.

“When the ear is exposed to loud noise, it can suffer from a temporary hearing reduction, also called auditory temporary threshold shift,” explained Dr. Zawawi in a McGill University Health Centre press release. “This disorder is usually reversible in the first 72 hours after the exposure, but if symptoms persist, the damage could become permanent.”

Using an animal model, two groups were exposed to 110 dB for an hour, which is essentially the equivalent of a 60-minute loud rock concert. One group was given caffeine every day, whereas the other received no caffeine.

After one day, both groups demonstrated a similar amount of hearing loss, but eight days later, the group that did not consume caffeine completely recovered. However, after consuming caffeine every day, the experimental group continued to have a hearing impairment.

“Our research confirmed that exposure to loud auditory stimuli coupled with daily consumption of 25mg/kg of caffeine had a clear negative impact on hearing recovery,” said Dr. Zawawi.

While more research is needed in order to understand the possible effects that caffeine may have on the hearing loss of humans, the results are “promising,” according to the release.

Maybe we should get a juicer and gradually replace the caffeine in our diets.

Coffee Might Not Actually Keep You Awake

category:

By Cooking Panda

Looks like coffee can only keep us alert and happy for so long.

According to research presented at the SLEEP 2016 Conference, coffee leads to more harm than good if you are constantly sleep-deprived.

Study participants were instructed to sleep for 10 hours a night over a five-day period, according to the American Academy of Sleep Medicine. After which, the 48 individuals were limited to sleeping a mere five hours a night.

Half of the group received 200 milligrams of caffeine twice daily, which is the amount in a cup of strong coffee, while the rest of the participants were given a placebo. Both groups were presented with various tests to measure their mood, cognitive abilities, and wakefulness.

Based on the results, the caffeine was only effective for the first two days of sleep deprivation. After that, it was no more effective than the placebo.

“We were particularly surprised that the performance advantage conferred by two daily 200 mg doses of caffeine was lost after three nights of sleep restriction,” said Dr. Tracy Jill Doty, lead author of the study and research scientist at Walter Reed Army Institute of Research.

“These results are important, because caffeine is a stimulant widely used to counteract performance decline following periods of restricted sleep,” Doty continued. “The data from this study [suggest] that the same effective daily dose of caffeine is not sufficient to prevent performance decline over multiple days of restricted sleep.”

Furthermore, the participants in the caffeine group also said their mood was greatly affected over the course of the study. In fact, it appears that it’s better not to consume caffeine regularly if happiness is important to you.

“Likewise caffeine effectively increased sleep latencies and improved ratings of happiness only for the first few days of sleep restriction,” Doty explained, as reported by The Telegraph. “In fact over the final days of SR those in the caffeine group rated themselves more annoyed than those in the placebo group.”

As coffee has been forever deemed as possessing energy-boosting powers, more research needs to be done to determine the long-term effects of this reported misconception.

Or maybe, just maybe, we could try to get more sleep.
