Freshness & Storage
Should You Refrigerate or Freeze Coffee?
Refrigerating coffee introduces more problems than it solves. The refrigerator is a humid environment, and coffee — being porous — absorbs moisture and odors from the surrounding air. Beans kept in the refrigerator can develop off flavors picked up from other foods, and the humidity accelerates staling rather than preventing it.
Freezing is a different story. For long-term storage of coffee that will not be drunk within a few weeks, the freezer can extend the bean's life significantly. The key is sealing the coffee in an airtight container before freezing, removing as much air as possible, and thawing only the portion needed at any given time. Repeated warming and cooling damages the coffee, so portioning into small sealed bags before freezing works better than freezing the whole batch in one container.
For coffee drunk within two or three weeks of roasting, room temperature storage in an opaque, airtight container is the simplest approach and produces the best results. Café de Volcán recommends buying coffee in quantities that match actual consumption patterns, storing it properly at room temperature, and treating the freezer as a long-term option rather than an everyday choice.
