looking very professional there
Today I bottled 375 bottles of 2020 red wine:
1. Merlot from Livermore
2. Cabernet Sauvignon from Livermore
3. Cabernet Sauvignon from Knights Valley
4. A blend of Zinfandel (Lodi) and Petite Verdot (Knights Valley) that I've named Synergistic
5. A blend of Merlot, Cabernet Sauvignon and Petit Verdot that I've named Soiree
All of these were barrel aged for just under 7 months and were bulk aged prior for approximately 7 months.

Yesterday I was doing a rack and return on my last 2020 barrel when I found a 6 gallon carboy of 2019 Grenache hiding in the corner. It had a solid bung and per my notes it was last sulfated in January 4 2020. The notes say it was sulfated to 65 ppm at the time. A little concerned I checked the free SO2 and it was at 9 ppm. This is after 2 years of not touching it which I find extremely interesting.
So I thought I'd bottle it today. I already filtered it with a 1 and then a .5 micron though it was really clean to begin with. The pH was 3.52 so I took the sulfite level to 40 ppm. It has a bright cherry nose and an extremely long lasting grapefruit finish though the mid palate is a little lacking. I have peach, Chardonnay and Viognier I may play around with adding a little but probably going to keep it the way it is, perhaps a little glycerol.

Fred, I’d like to hear more about what you find interesting. Interesting that a sealed (solid bung) carboy would loose free SO2 to that magnitude over two years or that it didn’t shed more?
I’m asking because I have wine in carboys that are about 2-2.5 years old now and need to bottle. My assumption has been that leaving it alone in a dark basement is enough to keep it stable as long as it’s topped up and has a solid stopper.
I’m in your classroom…
Thanks for the explanation, Fred. I'm going to test a few of my own and let you know what I come up with. It won't be for a couple of days, however.Yes, the fact that it still had that much free SO2 left is what surprised me. This is an extreme case but kind of confirms my thoughts that a 1/4 tsp every 3 months is not necessary.
I wouldn't want to make a habit out of letting my wines get to 9 ppm but the wine shows no signs of oxidation.
