How big of a boil kettle to buy

[Ryfrei]

is a 15 gallon boil kettle big enough for 10 gallon batches?

 

[chefmike]

yes. I usually do 11 gallon for double batches to get 10 to fermenters, which is 12.5 gallon preboil. I have no problem in a keggle.

My preboil volume is 13.7G it's tight in a 15G pot. If you are careful it will be OK, That being said I would get the 20G if I had to do it again the cost difference wasn't much

15 gal is fine for double batches, (for me, 11 gal into 2 fermenters). Watch close for foam before the hot break, or say eff it and hit it with some fermcap. No worries.
