DUH, I'm 32 and obviously don't know how to read and just noticed it now. PRIMARY fermentors.... I don't primary ferment in Carlo-Rossi jugs... I do that in a small white pail I got at the local winemaking place when I started this hobby. It holds rougly 1.75 gallons, so I usually make 1.5 gallon batches. The extra 0.5 gallon is handy when I rack and need to top up. The .5 goes into those smaller carlo-rossi jugs (duh, half the size), which take the same sized bung as the 1-gallon jugs.
Sorry for my mistake. It's been a nerve-racking week.
