Recently I just bought a 15 gallon food grade drum from an auction. I am going to convert this into a 15 gallon fermenter for my 11 gallon batches. I plan on installing an airlock on top, and then a valve towards the bottom. I see the spiedel fermenters come with plastic valves. I'm wondering if I would be better off going with SS setup, I'm thinking of these two items.
