Okei 1,
I note that you are using inert gas. I have been doing the same but no one else on this forum has indicated they are. I light of the recent news FVW newsletter, I'm frankly a little worried that I am not getting enough 02 to the wine (mainly almost none). Have you been doing this for a long time? I am a relative newbie trying to make sense of the art of this hobby.
Any thoughts on the 02 question?
