Anyone know about how much additional gravity points would be attributed to about 6 lbs of raspberries? I’m guessing .010 above the base SG.

Retake gravity measurements once you add the puree, then see how much ferments out.

The issue is that fruit adds water in addition to sugar. Odds are 6 lbs of raspberries won’t appreciably change the alcohol content unless the beer is especially high or low alcohol to start.

6lbs. of raspberries has about 100g of sugar, so this adds roughly 0.003 to the SG and produces about 0.4% more booze.
