FYI, don't use any of your old stuff (fermenters, spoons etc) for gluten free beer. Buy brand new stuff.
Metal and glass is ok to reuse if it hasn't got any scratches. What types of beers did you like to drink before getting your diagnosis?
I'm 3+ years in as a Celiac and 1 year in as a gluten free brewer. This year has definitely been the most fun
