So I've Googled around and opinions seem quite varied (?), so I'm looking for anecdotal experience:
I'm planning my first 10 gallon batch hopefully this weekend, and I've got a new 20 gallon kettle to use for it.
Is my boil off rate likely to change?
Average of my last ten 5 gallon batches in the 10 gallon kettle: 4.1qt/hr boil off. Exposed surface area of the liquid is 1017 square cm.
Surface area in the new kettle is going to be about 1590 square cm, almost 60% increase from the old kettle. I'm sure there is real science on whether this matters at all, but what have you actually observed in this situation? Should I assume a proportionally increased boil off rate, no change, something else? Thanks.
