3G batch fermentation in 7.9G bucket

[dcbrown73]

I've recently picked up four 3G carboys. If I wanted to make three gallon batches of wine (like the Dragon Blood wine), can I still use the 7.9G fermentation bucket even with that much headspace? I know fermentation creates a lot of CO2 and that protects it in primary fermentation, but I'm not sure if it's still okay at 3G instead of 6G.

Or should I look at finding a smaller fermentation bucket?

It's fine, just rack out of bucket @ 1.00-1.002 SP into 3 Gal carboy.

Having a lot of head space during fermentation is actually a good thing. That's the one time you don't have to worry about O2 exposure, because the yeast actually NEED O2 to build the colony and do their business.

You are fine, extra head space in a fermenter is great.
