Enter the total volume in the fermenter (gallons) and the average losses (gallons) into the Pre-Boil Volume Calculator. The calculator will evaluate the Pre-Boil Volume. 

Pre-Boil Volume Formula

The following two example problems outline the steps and information needed to calculate the Pre-Boil Volume.

PBV = VF + AL

Variables:

  • PBV is the Pre-Boil Volume (gallons)
  • VF is the total volume in the fermenter (gallons) 
  • AL is the average losses (gallons) 

How to Calculate Pre-Boil Volume?

The following steps outline how to calculate the Pre-Boil Volume.


  1. First, determine the total volume in the fermenter (gallons). 
  2. Next, determine the average losses (gallons). 
  3. Next, gather the formula from above = PBV = VF + AL.
  4. Finally, calculate the Pre-Boil Volume.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total volume in the fermenter (gallons) = 3

average losses (gallons) = 1.75

PBV = VF + AL = ?
