Cherry puree alchohol contribution

[TheMerkle]

Is anyone familiar with how to measure ABV when using a secondary fermentation on fruit? I would assume I could just compare my OG and FG from the primary fermentation and notate my ABV, then rack onto cherry puree, agitate, and take a new OG reading to later compare to the second FG, and add the results together? ...or am I oversimplifying this??

Since your using purée you could take a hudrometer reading before adding the purée and then after adding it. Then take that difference and add it back to your og. Then before you bottle or keg take your fg.

Look up the nutrition facts of the puree you're using. In the U.S., it would be on the label. If you're pureeing it yourself from fresh or frozen fruit, you can google for the info. Do a little math to figure out how much sugar you are adding to the beer and use your brewing software to calculate the resulting ABV with the yeast you're using. Add it as sucrose.
