I have the SS brew tech 10 gal kettle and really like the quality. (next on deck for me will be their insulated mash tun).
I notice they have the 7 gal fermenter and a small 3.5 gal. I am planning my first BIAB batch next week (my neighbor loves the Irish Red Ale and I was just planning on bottling it all up for her). I never tried a BIAB so I thought it would be fun to try and see how it compares to my fly and batch sparge all grain batches.
So I was planning on fermenting the 3 gallon batch is a 5 gallon glass carboy . I am just curious if fermenting a 3 gallon batch in a 7 gallon vessel would be too much head space? Maybe the space would soon be filled with CO2 anyway.
I would further assume the 3.5 gallon vessel would be too small and result in quite a bit of blow off. Not sure what size batch the 3.5gal would be ideal for.
I have no dilemma now, as I have plenty of options on hand, but was curious after seeing the SS Brewtech bucket sizes.
