Brix: 21.0pH: n/aTA: n/a
Our 777 block is around 20 to 21 brix with medium sized berries and thick skinsl, but still tannic skin and green seeds. Still has another 3 weeks to go. 667 has slightly larger berries... probably 19 or 20 brix. Will probably pick them a week apart. The 115 is still looking great. Smaller berries/clusters and more like 18 or 19 brix... another week behind the 667.There is a fair bit of green "second crop" that we need to be careful we don't pick, but even if a little bit gets picked it is easily sorted out on the line.

Learn more about Veraison, Brix,
Veraison signals the coming of harvest. It is the stage of the ripening process when grapes begin to soften and change their color. At the beginning of veraison, the berries are hard, green and about half the size they will reach when fully mature. In addition to the outward changes to the berries, this 30 to 45 day period marks an increase in the level of brix, or fermentable sugar produced in the grapes.
Sugar concentration is a major physical property analyzed in grapes and wine. The amount of sugar available will determine the sweetness of wine flavor. Residual sugar is also important to know as any sugar present in wine is a potential substrate for microbial growth. Sugar concentrations are commonly analyzed by measuring the density of juice or wine. Brix is the unit of measurement used in the United States when analyzing density. One degree of Brix is roughly equivalent to 1% sugar in solution or 10 g/L of sugar. Density measurement is normally done with a hydrometer.
Sugar concentrations in ripe grapes will range in Brix values from the low to upper twenties. Full physiological ripeness in grapes is about 25 Brix. Values higher than that come from dehydration of the berries as they begin to raisin. Residual sugar levels below 0.4 Brix, or 4 g/L sugar are considered complete fermentations.
