Gang: I have a couple of beers that were made in the past few months that have a very sharp, harsh finish. The beers look good, smell good and taste good until you swallow and you get this really dry & sharp finish on your tastebuds. I had an issue once where my water filter cartridge coughed up everything it had previously filtered and it left a harsh flavor in a number of beers but that it not the issue here. I just filtered some water this morning and it tasted very good. The beers in question are a blonde ale made with 1272, a red lager made with 2308 and a Czech Pils made with 2278. All of these were made with some amount of distilled water to cut my bicarb and in between all of these I have made some outstanding beers including a West Coast Lager, a Mexican Dark Lager, an ESB and an "Extra Pale Ale" made with 2112, 2124, 1968 and 1056 respectively. I have been brewing for 14 years and just got my first mill last year. Does anyone think I could be sending my grains through the mill too quickly with my drill and doing too fine of a crush and bringing out tannins? My crush does not seem pulverized and I have not had any stuck runoffs. Plus, there are these other beers that have been stellar. I mentioned that these beers were "astringent" to members of another board but they thought my description was something other than astringency. Also, these are relatively low-IBU beers... anywhere from 25 to 40 maybe. Has anyone experienced this? Thanks Beerheads.
