Posted Thu Aug 23, 2012, 7:56am Subject: Burr grinder bitterness
After about 50 years of using a blade grinder and perfecting my recipes for a wide variety of coffees, just a week ago I purchased a Capresso burr grinder. Without exception, every coffee has been bitter in the extreme.
I have adjusted the grind from medium to coarse, with no significant improvement. I have increased the amount of water to no avail. Before I go back to the blade grinder, does anyone out there have a solution to my bitterness problem? Many thanks, Gates
Aside from the fact that the Capresso is more of a bean "crusher" than "grinder", and hence probably creating excess fines wo you're overextracting (just quick diagnostics), information of what coffees and how fresh they are, what brewing methods (pourover, press, siphon, etc.), other equipment, and range or water temperatures you're brewing with will be helpful in more accurately pinning down the problem.
Also your "recipes" - bean/water ratio, etc. will help in pinpointing issues.
However, as I said above, the Capresso is not a good grinder by any stretch of the imagination. The burrset is designed to pulverize, not grind, and pulverizing leads to excess fines, and hence to the bitterness of overextracted coffee.
