There are two types of filters available for drip coffee makers. The most widely used is paper, which is now available unbleached. The other is a metal or permanent plastic filter. Neither is inherently better, but they do produce different coffee flavors, as the paper filters tend to absorb the coffee oils. If you are heating water in a kettle, bring it to a boil, remove from the stove and wait for a few seconds before pouring over coffee.
Boiling water can scald the coffee grounds and taint the flavor.
We suggest that you start with less, while also considering the type of roast that you are using. Remember, it is all personal preference. Any brewed coffee will only stay fresh for up to one hour. The enemies of fresh coffee are oxygen, light, heat and moisture. The safest place to keep coffee is in an airtight canister or tightly closed Killer Java coffee bag on the countertop or in a cabinet.
