Do the beans go stale over time in a bean to cup coffee machine? Is it just the outer layer that goes stale? I don’t understand how ground coffee tastes stale after a few days in the fridge but bean to cup coffee machines seem to be designed to keep the beans at room temperature.
In: Chemistry
Coffee beans are degraded when exposed to light, air, or high temperatures. Keeping them in something airtight, placed somewhere dark, at room temperature, is fine.
