I have a 10 bbl system and am thinking of brewing some of my seasonals in half batches to turn them over faster. If I shut down the top half of my steam jacket in my kettle I think I won't have a problem there. My concern is with maintaining a constant temp in my fermenter. If I have 5 bbls of wort, only about the top 20-30% of it will be in the glycol lined portion of the fermentor. Is this enough to maintain a reasonably constant temp through out the fermentation and subsequent lowering?
Thanks in advance for any input.
