I agree. One thing to consider, the larger the volume of the container of wine, the slower it ages. They see this in very, very old (75 year+) wine, which was bottled in very large containers in France, rather than typically sized bottles. I don't know the exact math, concerning this, but if you are in a hurry to drink the wine, you won't want to leave it in the carboy over a year. I generally leave mine in the carboy for a year or so, but I am never in a hurry to drink it.
Turock, I have read from others who agree with you about kit wine degassing on its own, if left in the carboy under an air lock, so it must be working for some of you.
I can't say I personally have seen this happen. I have left gassy wine in a carboy with an air lock for 18 months (not any more) and still had noticeable CO2. But, to be fair, maybe the reason why this is the case for me is I store my carboys in an area where the temperature never gets above 62F and is usually in the upper 50's F.
I know that white wine from fresh grapes is subject to the same CO2 issues as any kit wine, because neither gets pressed after fermenting. So, both these types of wine should need degassed. I am not a fruit wine maker, but I assume they would have the same issues, if they are not pressed after fermenting.
What I am trying to say is, since you actively make fruit wines, you should be experiencing the same problems with CO2 as most kit wine makers do, so I don't know why you would see degassing over time and not others of us.
Again, maybe it is the low temperatures, where I store my wine in carboys.
