Do use enough coffee! We recommend 1-2 tablespoons per 6 oz. cup - or about 1.5 inches of coffee in a BUNN flat-bottom filter. With too little coffee, grounds get over-extracted, leaving a bitter taste.

Do store grounds in a dry, airtight container to preserve freshness and flavor. Avoid excess heat or cold and remember - bean and grounds have a 'best before' date!

Do use the right-sized filter, and toss the filter and grounds right after brewing to stop bitterness from dripping through.

Don't 'bake' your coffee! If you're holding coffee for more than 20-30 minutes, use a thermal carafe - it'll stay fresh and flavorful for over an hour.

Don't reuse coffee grounds - used grounds don't have any flavor left.

Don't reheat cold coffee. Reheating causes bitterness.

Do clean your decanter daily. Acids and other organic materials can build up and spoil the flavor of your next pot.
