After a previous thread I realize that BIAB may be for me after doing several batches with a picnic cooler. I have about a 10-11 gallon pot and I was curious if an approximately 15 lbs grain build would be too big for my pot. I lose about 1.5 gallons of water per hour and when I did the calculations I see that I need about 9.5 gallons of water for this recipe. it has a 2 hour boil. I used the calculator on MoreBeer. Is there any other techniques I can use and still be a BIAV guy. U want to switch to this for simplicity and the ability to save time.
