I need a few more 5 Gallon Carboys, so I am looking into the Better Bottle route. I may as well get a 6 gallon while I am at it. I have a few questions though. First of all, the Ported Carboys. Do they work well? How much Yeast gets into your secondary by using the Port? Also, if I go with the Ported Carboys, does the fitting come with the Carboy so I can get my Wort/Beer out of the Carboy? Or is that a seperate item?
