Four Peaks Brewing Co.
High Gravity Forumula

During my 2007 Road Brewer trip, I spent a day with Andy Ingram at Four Peaks Brewing Company. Andy shared a formula with me for hitting a target gravity when diluting a high-gravity wort. Andy attributes his formula to the brewers at BJ's Brewery. A big thank you to Andy for sharing his formula with my readers.

(Gravity x Kettle Gallons) divided by (Target Gravity) = "Fill to" level of add-back H2O.

Useful for measurable, repeatable results.

Example = (15.5 x 650) divided by 14.1 = 720.
