7 Best Coffee Concentrates for Instant Caffeine (2025)

If you know a thing or two about coffee, you might find the other brands recommended here too lowbrow. But can you out-taste a coffee sommelier? Kloo's coffee concentrates are curated by such tasters, also known as “Q Graders,” and I couldn't stop saying “Wow” out loud while I tested the brand's offerings. From the upscale, frosted packaging and shiny metal stopper to the included measuring jigger, I was impressed upon first glance. And once I mixed in a shot full of the extract-consistency liqu

Should You Skip the Iced Coffee This Summer Because of Dehydration?

You know the drill -- it's important to stay hydrated always, but especially in the summer heat. However, that message was taken to another level when the National Weather Service in Las Vegas advised residents across parts of Nevada, Arizona and California to avoid caffeine during extreme heat.

To see if we should actually put down our ice

Wait, Are We Really Not Supposed to Drink Coffee in the Summer?

12 Best Coffee Subscriptions (2025), Tested and Reviewed

FAQ What Kinds of Coffee Subscriptions Are There? AccordionItemContainerButton LargeChevron There are two kinds of coffee subscription providers: roasters and retailers. Roasters are cafés, and small-batch producers who buy raw beans from farmers all over the world and roast them to perfection. By buying from a roaster, you're directly supporting the people who make your favorite coffees; there's no middleman between you and your coffee. The downside is you usually won't have as broad a selecti

Americans Are Being Told to Stop Drinking Coffee in the Summer Heat. I Reached Out to Experts for the Tea

In response to heat waves across the US, NWS Las Vegas, the National Weather Service for southern Nevada, northwestern Arizona and southeastern California, posted an extreme heat warning on X.

13 Best French Presses (2025): Plastic, Glass, Stainless Steel, Travel

The French press is an unassuming piece of coffee-making equipment. It doesn’t require electricity, yet experts agree that it can brew a richer and more full-bodied cup of joe in comparison with its more technologically advanced peers. For example, natural oils that would otherwise be filtered out in a drip coffee maker remain fully intact, making the coffee aromatic and robust. The French press method of making coffee is straightforward, cost-effective, easy to do, and hard to mess up. The dev

Good News! Caffeine Might Help Your Cells Live Longer

As if we needed any other reason to drink coffee or tea, new research provides insight into how caffeine supports health and longevity. Researchers in London studying fission yeast—a single-celled organism similar to human cells—have revealed that caffeine impacts aging via an ancient cellular energy system. Their study, published yesterday in the journal Microbial Cell, bolsters previous research suggesting that caffeine reduces the risk of age-related diseases and carries important implicatio

Backyard Coffee and Jazz in Kyoto

One of the things I read about while getting ready for our vacation in Japan were these famous tiny businesses: bars or izakayas with four seats, narrow little bookstores or record shops in people’s houses or the bottom floors of small buildings, hyper-specialized or themed bars owned by one passionate guy. (There’s one that’s chock-full of Star Wars memorabilia, for example.) We got to visit a couple of such places, and saw many more from the street. I’m planning to write a longer, more themat

Is Green Tea Really That Good for You? The Health Benefits You May Be Missing

So many of us need that morning coffee to get us through our day. One estimate says that 85% of US adults enjoy up to two cups of coffee daily. That being said, not everyone loves the taste or the side effects of coffee. The caffeine jitters and the trouble sleeping can be stressful. Looking for an alternative that will give you the energy boost without as many side effects? Green tea is a popular and tasty and it also has three times less caffeine than coffee as well as additional health benefi

24 Best Flavors of AriZona's Iconic Iced Tea (2025)

The internet loves to wax poetic about the eternal virtue of Costco’s $1.50 hot-dog-and-soft drink special, but where’s the love for AriZona’s 99-cent tallboys? Aside from a brief gag in a 2016 episode of Atlanta, very little fanfare is given to this under-costed dynamo of flavor and refreshment. Thirsty folks from all socioeconomic strata instantly recognize the colorful 23.5-ounce cans in their local bodega, and most flavors can still be found for 99 cents (plus applicable taxes and deposit fe
