Now that I've got a few 5 gallon batches under my belt, I want to start doing some recipe crafting, etc. I'd like to dial in to a pale ale that really works for me. I don't think I want to do it in 5 gallon batches. Seems like too much product for what I'm considering a series of incremental (and sometimes competing) experiments in recipe changes. So I'm thinking about doing 2.5 gal batches. The question I have, is what equipment do you use for fermentation (primary and secondary)? Mostly concerned about oxidation while sitting in the fermenter(s) with a lot more headspace due to the lower liquid volume.
Any insights/suggestions/recommendations would be greatly appreciated.
