This is one of the big questions in life--to drink caffeinated or decaf coffee? A great coffee house in San Francisco's Potrero Hill used to have a t-shirt that said "Death before Decaf". I understand people's passion--besides the nice buzz, many people sincerely feel that Caffeinated coffees simply taste better. Maybe it's something to do with the process that removes the caffeine from the coffee. I'll report on this and get other opinions in the future, but for now I just want to give my two cents. I drink both Caffeinated and decaf coffees. I realize I'm not super-picky, but I personally have found very little difference in taste, as long as the beans are from a quality source. I generally switch to decaf after 2 cups of the morning "jolt". Also, I have a general rule of avoiding caffeine (in just about any form) after 4PM for a quality night's sleep. Much more to come on this--Here's another T-Shirt I got from Farley's years ago-
