I use only purified water and grind all my own. We get Gevalia via mail order and all of their coffees are very good. I really like the Costa Rican Peaberry. Peets Coffees, some of the Trader Joes blends....like Bay Blend and Mocha Java are excellent. And if you are also a cigar smoker....go to JR Cigars.com and check out their Monte Cristo and Mayorca brand beans....very good.
