Time to Check on Some Preharvest Numbers

We feel that our vines are about a week behind their usual harvest date. On Sunday, September 19, we took in a representative sample from the Auxerrois, usually the first variety that we harvest and our Chardonnay, the second variety that we harvest.

The numbers that we got were the following:

Variety	Weight	Volume of Juice	Brix	pH	TA
Auxerrois	129 g	50 mL	18.0	3.36	9.9 g/L
Chardonnay	139 g	65 mL	18.6	3.04	8.0 g/L

We typically do not see such a high pH for the Auxerrois at this stage so that is something to keep in mind as we plan for our harvest date.
