my favorite medium roast bean is kicking horse three sisters blend
i'm told that serious coffee aficionados insist on burr grinders for grinding their beans
i recently picked one up on sale at cambodian tire. the coffee definitely tastes different - all the 'raw' tastes that come from the inclusion of ultra fine grinds are removed, resulting in a smoother taste to the coffee. unfortunately i had kinda gotten used to the raw taste and had gotten to like it, lol!
but i'm starting to really like the burr grinder taste, and i doubt i'll go back now
also, make sure you use water with no off tastes to make your coffee. bottled water will do fine, or if you don't want to use bottled, one of those brita carbon filter carafes will do a good job. just make sure to change the filters when you are supposed to, because when the carbon gets saturated, then it starts to leach off tastes back into the water
