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:
- 0.5 ml (5 drops) wine into the test tube,
- add the AimTab and don't burn yourself (Warning! Contains sodium hydroxide...),
- wait for the sort of violent, hot, boiling reaction, and
- measure the resulting color in the test tube against the "2 drop" color chart.
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.
