Two questions:
One, Im brewing a three gallon batch tonight. Would it be a bad idea to ferment three gallons or so in a five gallon carboy? My other option is to use three 1 gallon Demi johns which tend to pop off stoppers at high krausen because of their size. It also makes it harder to pitch the yeast from one vial evenly

Second question, I have a vial of white labs yeast. Would I be way over pitching using all the yeast on only three questions?

Cheers

I prefer a five gallon carboy. Give you enough room, and the yeast evens everything out. You get a better ferment when the test goes through a whole give stage life cycle..

1) No problems with a 3 gallon batch in a 5 gallon carboy.

2) No, I donít think youíll be over pitching; if anything by not making a starter, you may still be a bit under. Always make a starter, youíll ferment faster, cleaner and have better results overall.

Thanks for the replies. I kind of figured the yeast wouldnít mind the extra oxygen in the headspace and would form enough CO2 to push all the excess oxygen out. Just needed some confirmation from others

This...

Unless you plan on aging the beer for a long time in the 5 gal carboy, you will be fine using it for 3 gal.
