Harvest 2016 Update #3

Harvest Update 2016 #3: Sauvignon Blanc Fermentation

“We started our first day of harvest on Aug 16, 2016 with our Pinot Grigio, then segued into our Sauvignon Blanc on Aug 19, and completed our last Sauvignon Blanc harvest on Aug 26. We will now have roughly a 2-week window between our next picks, particularly with the cooler weather we are experiencing.

We have a new planting of Chardonnay at our Lavender Hill vineyard that is about 2 weeks away. Also, we have Merlot at the Komes Ranch at the Flora Springs Estate that is approximately 2 weeks away as well.

The Pinot Grigio and Sauvignon Blanc are fermenting at the moment. In the first photo, you will see a Sauvignon Blanc fermentation taking place in a temperature controlled stainless steel tank – These grapes were picked at 23.4 brix, and is currently at 5 brix. As the yeast consumes the sugars, you get approximately .6% alc per brix, so the current alcohol is about 10.4%, and once the yeast has consumed all the sugars, the final alcohol will be roughly 13.9%. We ferment at 55 degrees F, and the process takes roughly 3 weeks or so. We raise the temperature towards the end of fermentation as to prevent yeast stress and ensure the fermentation will reach completion.

In the second photo you will see some 60 gallon oak barrels, as well as some 135 gallon oak puncheons that are being used to ferment Sauvignon Blanc as well. You will notice a series of stainless tubing connected by glycol hoses. We have this manifold system connected to a thermostat where we are able to control the temperature of the fermentation just like in the tank. The plastic bag you see on top, just seal the bung holes, will allow CO2 from the fermentation to escape.”
