CoCo,
Kona is excellent, but expensive for the real deal. Great for special occasions. Kenya is my favorite. I take it black. I also like a good Sumatra, but not too dark. Guatemala french roast is about the only dark roast I care for, usually with cream and sugar.
Besides good coffee, you need good water. Filtered, fresh, that tastes good before brewing. Distilled is not recommended since it leaves coffee rather flat and not fresh tasting, it needs oxygen and some minerals.
Like Dagney, I brew strong and add water if it's too strong.
But if it's weak, just add cold water and feed it to the plants.
Of course, it helps to be near a real coffee roaster, where you can get the coffee fresh, within a week of roasting. Otherwise, learn to roast your own! http://www.sweetmarias.com/ ... not affiliated with Billy the ExBethelite Industries, Inc.
