Me again,

How about this question? I bought a 50 L barrel a couple of years
ago. The first wine I put through was a second run on a cabernet.
Wasn't expecting much from it and that is what I got. I then put
through a cabernet (parent of the second run) and while topping up,
would leave a half bottle of wine on the shelf waiting a couple of
weeks for top up. Someone on this board told me to stop that as I was
probably oxidizing the wine in the barrel. I did stop but the wine
was pretty bad, tasted oxidized I think. I have another wine in the
barrel, a blend of Mouvrede and Cabernet that I top up carefully using
similar wine from stubbie beer bottles.

My question: Did the oxidized wine I had in that barrel damage the
barrel or will it still perform ok?

Thank for you help.

Dan
