I've been using them for the past 2 years, in PET carboys with no ill effects. Most all of my wines stay in the carboy for about a year before bottling. I love the fact that I don't have to worry about my air locks going dry. I currently have 8 carboys, at various stages of aging with breathable...
That looks a lot better! I wouldn't be any hurry to bottle. At a minimum, I would give it 3 months in the carboy before bottling. 6-12 months is when I normally bottle.... Leaving it in the carboy will also keep you from drinking it before it's time... Saluti!
Just curious, what's the longest time you aged your wine in a carboy? Personally, I try to bottle after about a year. I use silicone, vented bungs for aging too, so I don't have to worry about my airlocks going dry.
I had that happen myself, while carry a box down the cellar steps. The bottom blew out, and wine tumbled down about 10 steps like a slinky. Thank god the bladder didn't break! It's always in the back of my mind now when carrying a box.
