This simple trick has what it takes to reignite your romance with coffee.
Looking to elevate your cup of coffee from simple to spectacular? All you have to do is one easy, science-backed trick. Chemists at the University of Bath collaborated with a British cafe to discover how the temperature of coffee beans affects flavor. They found that chilling coffee beans before grinding them resulted in a more tasty and aromatic dose of caffeine.
“What you’re looking for is a grind that has the smallest difference between the smallest and largest particle,” said Christopher Hendon, a chemist who was involved in the study. “If you have small grinds you can push flavor extraction upwards. We found that chilling the beans tightens up this process and can give higher extractions with less variance in the flavor—so you would have to brew it for less time or could get more coffee from the same beans.”
Cool, right? Instead of storing your coffee in your cupboard, try sticking it in an airtight container and toss it in the freezer the night before you grind and brew. And if you’re finally ready to give up the instant stuff thanks to this trick, try your hand at it.
