I have 30 gallons of Cab Sauv in a 30 flex tank with french oak staves. The wine is with in less than an inch of the top of the tank. It has been aging since early November. I drew a sample today from the sampling valve and it smells and tastes great. I opened the top of the tank and I noticed what I thought smelled like mildew or green apples. I drew a sample from the top and it indeed smelled like green apples. The taste was similar to the sample taken from the middle of the tank. I also notice sediment in the sample from the top.
Have any of you experienced this? Any ideas of what I should do? this is my first time making this quantity of wine and also the first time in a flex tank. The sample from the sample valve is great and probably the best cab I have ever made, I don't want to risk losing the entire 30 gallons.
