How should I store coffee beans to keep them fresh?

Store whole beans in an airtight container at room temperature, away from light, heat, and moisture. Don't refrigerate or freeze daily-use beans — the temperature cycling causes condensation. If you buy in bulk, freeze in sealed portion bags and thaw completely before opening. The biggest enemies of freshness are oxygen, moisture, heat, and light — a good ceramic or glass container with a one-way valve is ideal for daily use.
