It sounds cruel, but it's a fact of life. Air and moisture are the enemy of your coffee beans, so if you're looking to make that perfect cup of coffee:
- Store your coffee beans in an airtight container. I'm a fan of canning jars.
- Grind the beans only as you need them.
- Don't freeze your coffee if you want it to keep it's maximum flavor.
- Buy only what you'll use within a week or two; coffee goes stale quickly.
