Carboy Size

[Duffey]

I just received a free 25L glass carboy from a friend that I want to use as a secondary. My beer, after evaporation during the boil and racking from primary to secondary, ends up with about 17L in the secondary. Would this be too much headspace in the new 25L secondary?

Thanks.

It will work just fine.

The headspace will fill up with CO2 and blanket the beer, say thanks to your friend!
