Have two methods:
1 Keurig... when I have no company and need some java fast, almost daily.
2 grind and drip...I have an old style hand operated coffee grinder. Beans are from two places in Africa and my nephew who has his own import/export coffee business. I grind the beans and place them in an old style drip coffee cone filter. Then I gentle pour boiling hot water over the grounds and everything on the counter top.
Method number 2 takes time, but it is probably the best coffee for those seeking flavor and caffeine.
