Most people pick a brewing method based on how it tastes, how easy it is, or what they’ve always done. It doesn’t come up very often at the counter that the method itself might affect how much of a compound that helps your brain ends up in the cup. But scientists who study coffee chemistry in depth have been asking that very question, and the answers are really interesting. It is chlorogenic acid that is at the heart of this. As much as eight percent of the dry weight of Arabica beans and even more of the dry weight of…
Thursday morning in November, the sidewalk in front of a Starbucks on Lafayette Avenue in the Clinton Hill neighborhood of Brooklyn didn’t look like it does most of the time. It wasn’t the usual line of people holding their phones and waiting for their orders. Instead, there were picket signs, chanting, and the air was about 40 degrees and very cold. Baristas in aprons stood with union supporters and told people who came in for coffee to keep walking. A lot of them did. The strike didn’t just happen at one Brooklyn location. It was planned to happen on Red…
It’s not often that a food that most people think of as a treat is used in a serious study on aging. But that’s pretty much what happened when King’s College London researchers wrote about theobromine, a natural compound found in cocoa, and how it seems to be linked to how quickly people age. The study, which came out in December 2025 in the journal Aging, looked at biological age markers in the blood of almost 2,000 people from the UK and Germany. A simple but surprising main finding was that people whose blood had higher amounts of theobromine always…

Yes, coffee that has already been ground can be put in a French press. But the results depend on what you have and how willing you are to let go of your morning coffee. Most of the coffee in grocery stores is ground to be used in drip machines. That means the particles are pretty small so they can work with paper filters and a certain rate of flow. The way a French press works is different. Since it has a metal mesh filter and full immersion, the grind size that works well in a drip machine doesn’t always work…

A mug of hot chocolate on a chilly nite has an almost therapeutic quality. Warm, sweet, and a little rich, it falls somewhere between comfort and dessert. People have been using it as a coffee substitute for years, believing it has no negative connotations. There’s no reason to feel bad about having another cup, no jitters, and no late-night awakenings. As it happens, that assumption is largely correct, but not totally. Caffeine is present in hot chocolate. It’s not much, but it exists. A typical eight-ounce cup of a powdered mixture, such as Swiss Miss, contains about five milligrams of…
Reusing your morning coffee has a profoundly fulfilling quality. It feels clever, almost moral, to pour those dark, earthy grounds into a pot or scatter them around a garden bed. Additionally, the notion that coffee grounds are a nearly universal plant food—some sort of free fertilizer that can be found in your kitchen every morning—has been circulated for years in gardening circles. However, it’s not that easy. Coffee grounds actually help some plants flourish. Others endure silent suffering as their roots struggle in excessively moist, dense, or chemically hostile soil. The issue is that most gardeners don’t realize what category…
Most coffee drinkers have experienced a shift at some point, usually around cup number three. Behind the eyes, there was a low hum. a heartbeat that is a little faster. Maybe that’s enough for today, the thought went. Then there was the question of how much caffeine was actually in that, which is rarely answered exactly. As it happens, the number varies more than most people think. The average amount of caffeine in an 8-ounce cup of brewed coffee is between 80 and 100 milligrams; however, when real-world brewing practices, cup sizes, and bean varieties are taken into consideration, researchers…
Every morning, a small ritual takes place in millions of kitchens: the coffee maker completes its cycle, the grounds are scooped out, and they are carelessly thrown in the trash. It’s the kind of thing that most people never consider. However, citrus growers—lemon, lime, orange, even the tiny Meyer lemon perched on a sunny patio—have begun to wonder if something that is typically thrown away might be better placed in the ground. In a nutshell, citrus trees can benefit from coffee grounds. However, most enthusiastic gardeners ignore a few crucial disclaimers in the longer response. The nitrogen content of spent…
