Almost finished
I took 2 samples, one from each demijohn, Left and Right when looking at them from the table. We took them to BevPeople for ML testing:
- Left sample: 16.8 ppm (.0168 g/L)
- Right sample: 26.8 ppm (.0268 g/L)
We started at 2.5g/L, and .03 g/L is considered complete, so we are officially done. We decided to let it sit one more week or so to make sure, then we’ll rack and sulphite.
I also asked Bob at BevPeople to have a sniff and see what he thought. I was expecting him to comment on the amount of oak. He said it has some H2S! What? He even got out the copper sulphate, and put in a few drops and we compared a cup with and a cup without the CuSO4. Noticeable difference, indicating that there was indeed some H2S type problem. I want to try this myself at home. I really though this was an over oaked wine.
Maybe this aroma is due to the MLF itself? I have read that MLF’s can produce some off odors, and that racking will help eliminate it.
We should wait a week or so to make sure the MLF is done. Then rack it into new containers with tswome aeration and sulphite the wine. Let it sit a day or two, and resample it. See if some of this off odor is gone.
