Surprise! First bubbler action in the CB, and creepy gaping foam in the primary. Late and sleepy, did not take any measurements, but the smell of fermentation is all through the house.

Cellar 71F, Outside 50 F, juice 66 F. Brix 22 (maybe 22.5) in the primary tank
No surprises. No real sign of fermentation yet, and I'm not expecting any until this evening, and would not worry about there not being any until tomorrow morning.
Just for yucks, I used two different hydrometers for the brix reading. I wanted to test my worry that the older hydrometer's scale has slipped. Verdict: not so much. There was maybe half a brix difference between the two, and of course I couldn't say which was more correct. But the new one has fancy colors, so that's the one I'll use.

Shag, Momma, shag! Might take a temperature or brix reading later this evening, but both vessels have started to ferment. The shag in the primary is deep and bubbled, the CB more pf a stout's priest-collar. Neither is pushing the bubbler, but there's a lot of head-room so I'm not expecting much.

First there is a mountain...
Cellar 73 F, Outside 49 F, juice 70 F. Brix 20.5/23? in the primary tank
OK, pic below is of the priests's collar that's still in the CB. But the shag in the primary that was there at 1800 ... disappeared! In it's place, though, is the fizz of ferm: listen to the audio here. The big brix span I'm listing is because 20.5 is what I first got in the tube, but after leaving that to tend to the tank temp, when I returned to the hydrometer it had hoisted to 23. I think that higher reading was due to the fizz / bubbles lifting the hydrometer in the tube. I trust the low reading.
Tent, sorting table, and all of the small gear up and in place by 7:30 AM. Didn't rain a drop while putting things out, then there was a short wave of pretty heavy rain.
We're sitting pretty. Light rain ending around noon. I think we can be done sorting before then, or mostly so, and bring up the destemmer and press when the rain stops, but your mileage may vary. Tic tic tic
10:15 AM: Sorting well underway. 8 of us out there now.
Well, posting dell off for the 2022 Chardonnay, but it was probably the best wine we've made. I'll try to keep things more up to date for this year's wine. Maybe I'll post some notebook pages to close out 2022.
Harvest is darned late! This will be the lates we've started by at least a couple of weeks. Once again we're going with Chardonnay from the Lanza vineyard in Suissan valley. 12 x 36#. Sister K has already picked it up and is driving down no.
Must has recommended Alchemy 1 yeast. Scott Labs says:
ALCHEMY I is a complementary blend of yeast strains that focus on thiol revelation, thiol conversion, and ester production resulting in intensely fruity wines.

Well, we did rack yesterday, and only lost a couple of liters of volume. We're cloudy now. Free SO2 barely dropped according to today's reading (a surprise), but the pH still shows wildly high (as disappointment). Have written Musto to see if they know what the pH was at the start - haven't heard back yet. And i've just ordered some tartaric acid, which should be delivered tomorrow.
The sample I've tested from has good color and tastes medium acidic, so I'm still puzzled by the pH.
This article has a formula for raising pH - but using it suggests I'd need a pretty massive dose of tartaric for each carboy. No way. So I just gave up and ordered a new pH meter - this time with calibration and storage solutions. Won't be here until Wednesday.
Meanwhile, I'll make some 10% meta solution and bump the free SO2 to 30 ppm.
0900:
Ready for racking, today or tomorrow.

Back from a few days away. Juice looks great, approaching clear. Will rack this weekend, if not sooner.
Pretty near dead-still, so am thinking about the SO2 level. Titrets test from carboy A indicated between 20 and 25 ppm free SO2 (20 to 25 mg/L). So I feel OK for a couple of days. But what level to boost it to when we rack? My inclination is to use a bigger boost on this racking than I have in the past, especially I get lazy about the timing of the next rack. Research!

More MLF testing and general observations.
The Accuvin chromatography test reads (to my not completely trustworthy eye) somewhere between 75 mg/L and the 110 mg/L from four days ago. Tough to pin down, because while the color looks right to me, it's much more opaque on the test strip than on the dot-printed color key. (If winemaker Fabricant were here he wouldn't be fooled.)
For a tad more detail, this Accuvin doc suggests that we're not complete, but are approaching the empty range between not complete (>75 mg/L) and complete (<35 ml/L). I guess that what lies between the two numbers is opinion.
Closer to still, fewer rising bubbles of gas. Not clear but the color continues to shift that way. Took some pics and will try to put together some comparisons for posting later in the day.
18:00
Woo hoo! Just tasted the juice again, and did an Accuvin MLF color test.
Taste: very different already than it was five of days ago. Less tart. Less weird.
And the test: I read it as 110 mg malic acid per liter (110 mg/L). Now I really wish I had tested last week so I would have the comparison. Sigh.
Brix is -1.7, measured from carboy A.
The juice is becoming more translucent, very noticeable in the hydrometer tube. Still far from transparent.
Purchased AimTab Reducing Substance Tablets, which seem to be the popular replacement for Clinitest. Have never used these before, but I wanted to see what an approximate chemical test would say in relation to the negative Brix readings. After futzing around a bit and realizing, no, I should not simply substitute wine for urine in the standard diabetics test... I found the relevant instruction sheet from the folks at Presque Isle. I assumed we are in dry range, so:
The result, to my eye, is 0.1% residual sugar in the wine. Does that translate to 10 grams per liter? Anyone? If it does, we're at the upper edge of "dry" (1 to 10 g/L RS), and well below the standard definition of off-dry (17 to 35 g/L RS).
All of which is another way of saying, Uh huh, going pretty well.
Also, I tasted the juice. Strange goings on at this point. Tart, apple-ish. Really living in the middle ground between wine and juice. Nothing bad, but maybe a taste that only a winemaker could love.

235 hours since inoculation and Brix is just a smidge above 0.5 (measured from carboy B). Steady as it goes. Very clean. Still waiting on a magical MLF decision (or non-decision, seeming ever more likely). And here's a pic of the lees settling in carboy A.

Not taking any direct readings this morning.
Everything looking exactly as you would hope. Super-clean. Each vessel's airlock popping every few seconds. All those mesmerizing pinprick bubbles sliding upward along the surface of the carboys.
Now the big question to consider: malolactic fermentation? What do we want to do? Promote it? Inhibit it? Just let the juice do what it wants to do and hope that MLF doesn't start or continue after we've bottled the wine for the party? We know we are not using oak: does that dictate anything re MLF for Chardonnay? The little reading we've done is not conclusive on the last point. We'll need to decide in the next few days. Green apples, or golden apples?
Here's a typically unhelpful (to me) article in Wine Industry Advisor. Something judgemental from Wine Folly. Maybe there's something helpful in this Wine Enthusiast article -
An unoaked version could also have buttery flavors, because the wine can still undergo malolactic fermentation in any type of container. Toad Hollow Vineyards has a perfect example of this in their Francine’s Selection Unoaked Chardonnay from Mendocino, which brings the butter without the oak.
So, quick, let's go get a bottle and taste it.
And, for what it's worth, when we made Chardonnay in 2016 we did not prevent or promote MLF, and we kept the free SO2 low - lower than I'd be comfortable doing this year. And in December MLF started up on it's own.

Juice is at ambient room temperature. Measured brix from a single carboy. Will rotate going forward.

So maybe we should start projecting out to when we might rack off the gross lees? Here's some white grape history.

Yeast action starting. 7:45 AM. |
After a pandemic hiatus of a couple of years, it looks like we're back. Targeting September 24 for the crush. Targeting grapes from the Lanza vinyard. No real details yet beyond that. Stay tuned.

QA23: Often used in terpenic whites, it enhances the aromatic aspects of a grape. In Muscat, QA23 really brings out the floral notes and makes an elegant, fruit focused, aromatic wine.Sister Karen will be driving the grapes down from Musto - 12 36# lugs.
