Brewed a Raspberry Ale on Sunday - by today I was adding 3.5# of raspberry puree to the beer. The label said the gravity of the puree was 1.04 - 1.053. The 3.5# is about a quart of puree. There were about 5.5 gal of beer in the fermenter. So question: How many gravity points did I add to my brew? Here's how I calculate it: If I were to add a quart of syrup at 1.05 and dilute it in 22 quarts of water, I'm adding about 2.27 GP (50/22). Multiply that by 3.5 pounds and I get an additional 6.8 points in the wort. Logic check: The OG of the beer was about 1.055, I'm adding puree at a lower OG than that. Okay, guys, did I get the calculation right?
