What size pot for a 15 gal. Batch?

[LuciferSam]

I am going to start all grain from extract, but I would also like to do 15 gallon batches to fill three Corny kegs at a time. My brew is too good I drink it too fast in 5 gallons. Could I use a keggle to boil in? Could I brew 10 gallons and add 5 water, similar to brewing 3 and adding 2?

I boil 13 gallons in a 16 gallon pot for a 11.5 gallon batch and you have to watch it at the beginning

or the hot break will boil over, so I am thinking for a 15 gallon batch you going to want at the least a 20 gallon pot if you are going to do full boils

if you do a partial mash with extract you can boil less, I do 11.5 gallon batches to fill 2 Corny kegs

I do not know if you are going to fill 3 with a 15 gallon batch

all the best

+1 - typically I see 20 gallon pots for 15 gallon. Ideally with all grain you're doing full boils - you could dilute out, but it'll affect your hopping ratios (utilization in a high gravity wort you're planning on diluting is much different than a lower gravity wort that won't be diluted).

Maybe 15 is too much? I like 11.5 to fill 2 corny kegs. Could I use a half barrel keg converted to a keggle to brew 11.5 gallons? Does anyone else do this? What other cheap DIY 15+ gallon brew kettles could I/you use?

I use my 1/2BBL keggle for both 5.5 and 11g batches (I always give myself 1/2g for trub loss in the keggle and racking from primary to secondary to keg).
As Brew_NY said, you have to watch at the beginning (or use FermCap) but it's easily done to make double batches in a keggle.

I try to squeeze 15 gallons using a 20 gallon pot on occasion, and usually fall a little short...a 25 or even a 30 gallon would be a better choice.

+1 to this. Some of my 11 gallon DIPA recipes start out with 15gal in a 20 gal vessel. It definitely depends on the beer your doing.
