North Texas Homebrew Supply will be holding a beer off flavors class this coming Sunday, July 30th from 2-4 pm.
If you are not sure what some of the common off flavors, such as diacetyl, dms, oxidation etc, actually smell and taste like, this is a great class to take. If you just want to improve your own beer, or want to improve your judging (think Limbo judging!) quality, I highly recommend this course, having taken it 2 years ago.
