Coffee snobs, listen up. If you grind your own joe, you should really be freezing your beans. Here’s why:
As you may or may not have noticed, coffee beans aren’t all the same size. When you grind them, the small grains taste slightly sour and big grains taste bitter. But storing your beans at a cold temperature keeps them consistently sized, and as result, your finished brew will have a more even flavor.
By contrast, if you store coffee beans at room temperature, they’re more likely to be inconsistently sized when ground. They can also absorb flavors and smells from the air--like that bacon you made earlier…or the new perfume you’re going a little heavy on.
Moral of the story: Cold beans make for a better brew.
