White Film In My Wine Barrel
Pete Russo — Newberg, Oregon asks,
I have a new 26-gallon (100-L) Hungarian oak barrel full of Merlot wine. When I went to top it off this month, I found a thick white film on top of the wine. It was so thick that it stuck to the wine thief when I took a sample to test for pH. The wine still smells and tastes OK. I have been making wine for 10 years and I have never seen this before. I added some SO2, over-filled the barrel until I didn’t see any more of the “white stuff” come out and put the bung back in. Is this something I should really be worried about? And is there anything else I should be doing?
