Here are a few simple and inexpensive ways to make a big difference: 1. Use good, clean water – Filtered water is best (not distilled) since minerals enhance the flavor. Coffee is 98% water, so starting with quality water can instantly improve your brew. 2. Store your coffee properly – Use an airtight canister and store in a cool, dry place to keep your coffee fresher for longer. 3. Use a scale for consistency – Even with an auto-drip machine, using a scale helps you optimize your coffee-to-water ratio. 4. Use a burr grinder – Whole beans stay fresher longer, and grinding them just before brewing ensures maximum flavor and control.
