North Texas Homebrew Supply is hosting an Off Flavors Class on Thursday. It is not just off flavors but many flavors you might come across in drinking or judging beer.
NTHBS is giving NTHBA members $10 off. The discount code is on the discounts page located here: https://nthba.org/discount-codes-at-homebrew-supply-stores/
The class prices with the discount are $19 for yourself and $33 (plus tax) if you bring a friend.
Sign up now. This is a great learning opportunity.
