That's certainly possible. However after my 7.5 gallon pot, my next biggest is 2.5.

Once you get the hot break settled you can add your hops for the hour of bittering.
My grain bill would be 15.5 lbs - which would mean a little over 5 gallons for the mash, right? That fits in my bottling pail.
How much would I need for the sparge?
I boiled 6.5 gallons last week and it didn't boil over (I was also quick draw with the spray bottle).
