Coffee freshness can be a touchy subject, but there’s no debate around pre-ground beans versus whole bean grinding at home. When a coffee bean is ground, it releases all the carbon dioxide stored inside — a reaction that triggers the release of bean’s moisture and aromatics, too. Buying pre-ground beans means you’re forgoing the flavors the bean carries.
Generally speaking, coffee grinders are either unaffordable and great, like Baratza’s ever-popular Virtuoso, or they’re economical to a fault, like hand grinders. Oxo’s burr grinder sits somewhere in the middle, and it’s 35 percent off on Amazon today through June 16 for Father’s Day.
