I have an American Wheat in the carboy ready to bottle. I was thinking of trying to take about a gallon of it and priming it with fruit juice to see what kind of character it gives. I wanted to check to make sure I'm running my numbers correctly.

My assumption is that you take the specific gravity of the juice and assume that anything over that of water is fermentable sugar. So, if my fruit juice had a SG of 1.035, I would assume that it has 0.035 gr/ml of sugar in it. If I wanted to use a typical homebrew priming value of 5 oz sugar per 5 gal batch, that would be 1 oz sugar for the 1-gal, which is something like 28 grams. Therefore I would need to add 28/0.035 ml of juice to my one gallon, which is 800 ml, or 1.7 pints. This is adding about 20-pct liquid to that gallon, where the result of which on the final beer isn't immediately clear to me other than getting a slightly lower carbonation value than anticipated because now my volume is increased.

Besides verifying that my reasoning is correct, does anyone have experience doing this, and does it have a noticeable effect on the beer?

Early in my home brew days I made a cantalope wheat beer. I saved some of the juice to prime with. It got left out at room temperature too long and did indeed effect the beer. But I ended up with a lambic like beer that turned out pretty good.

I've never tried to prime with fruit juice, but your numbers and thinking seem correct to me, Dave.
