Well, I've wanted to work on my barbera and cabernet for some time, and had every intention of doing so at the beginning of the month, until I figured out that my pH meter had pretty much died (was a pretty cheap meter anyway). SO, I eventually ordered another one online (a much nicer one that has 3 auto-calibration points, and adjusts for temperature), it came in, and I just got some time last night to do all of the measurements I wanted to do. Was trying to figure out where I was on free SO2 to see whether I should rack and add sulphite, or whether I was good on the sulphite and should think of bottling the wine. Plus, I just wanted to try the wine again and see how things had matured. The cab kit wine came first---tested the pH, found it was pretty low, then did a free SO2 titrate test, and found that there was something like 70 ppm of free SO2 in the wine---more than enough to kill any little critters that might be lurking in the wine. And the fact is, I haven't added SO2 to the wine since October. So what they say about kit makers loading the wine up with SO2 seems to really be true. Because it was really unexpected to have that much free SO2 in the wine. Am thinking I can probably bottle the wine at any point without any additional sulphite being added, and I'll be fine. Next came the barbera. I've had some problems with this barbera in that it was a high-brix grape that is now at 15.25% abv. But the pH is at something like 3.74, which is SUPER high (even after I've tried to adjust the acidity in moderate ways). SO, I know it'll take a decent amount of free SO2 to protect the wine. Did the SO2 test, and got around 65 ppm, which I think is pretty good for what the wine is. Chart says I need around 45-50 ppm, so think I'm probably pretty good on that front. Question is, should I bottle the wine, or do one more racking? There's obviously not a ton of sediment in the bottom of the Cab carboy since that wine was made from a kit. But I've racked it something like 3 times, and I don't really know what else I'll gain from racking it again (other than introducing a bit more oxygen, which it probably could use, truth be told). As for the barbera---there is actually some sediment at the bottom of the carboy, and think it probably could use another racking and 3 more months in another carboy to get rid of any additional sediment that might be suspended in the wine. But I hate to introduce a bunch of oxygen into a wine that has such a high pH. At the same time, I hate to keep sediment in the bottom of a carboy if the wine is prone to acetobacter because of its high pH. Crushed the grapes at the end of October, so has been going for quite some time. Any suggestions? Comments? Criticisms? Snide remarks?
