partial batch priming

[slez81]

Hey I'm kinda new to the forums here, hope this question is in the right section. I made a wheat from a recipe i got at my local homebrew store, left it in primary for a week until there was no more action going on, then I put it into two secondaries (about 2.75 gallons in each) and added raspberries to one of them. I wanted to try to do a raspberry wheat, but not lose my whole batch if i messed that part up. anyway, Im getting ready to bottle and have read several different suggestions as to how much priming sugar. any suggestions on how much for each 2.75 gallon batch? I will probably go buy a scale, though i havent yet. I am using corn sugar to prime. read somewhere that 5oz of that was about 3/4 cups, true as far as a conversion?

thanks a lot!!

For 2.75 gallons @ 2.5 volumes of CO2, assuming the beer is sitting at 75 deg F, you'll need 72 grams (about 2.54 ounces) of corn sugar to prime. Go out and buy that scale - cups are next to useless when it comes to measuring non-liquid brewing ingredients because the consistency of solid ingredients tends to vary.

Thanks a lot, but I read somewhere that wheats should be closer to 4.0 volumes of CO2, first is that true, and if so, how does that effect how much more would be needed? I'm not sure if that was good info that I had gotten, and i cant remember where i read it.

4 Volumes of CO2? You better use Champagne bottles then - regular bottles will not handle that kind of pressure. I can't think of any beer style that is so highly carbonated though. They rarely go over 3 volumes.

Check The Beer Recipator - Carbonation to calculate how much sugar you need to add.

I may be way off on all this, so go easy on me if so. But I followed that link to the calculator, at the very top you can select different styles of beer and it gives you a range of two numbers, i thought that was the suggested CO2 volumes for that style. And my guess what that I was to choose Wiezen for Wheat Beers, which says 3.6-4.5. Thats why I thought it was supposed to be closer to 4. Still fairly new to this (only batch 3), hence my confusion.
