Our last harvest of the year is olives, which we typically pick in late November or early December. In an ideal year, we might get some frosts before the olives are ripe, but we won't get any hard freezes, because if the olives freeze then they rot and aren't usable for oil. Like the rest of the 2012 harvest, we got pretty much what we wanted for our olive crop, and were able to pick ripe fruit yesterday under sunny skies.
Today, we processed the olives on site for the first time thanks to the marvelous mobile olive press from our friends Yves and Clotilde Julien of Olea Farm:
Yves and Clotilde's press (which they've named "Mill On Wheels") includes components -- some imported from Italy and some made locally -- that wash the olives and separate them from any leaf or stem material, that crush the olives into paste, that separate the liquids from the solids, and finally that uses a centrifuge to separate the oil from the water. I took a short video that tracks the process from the hopper full of olives through to the stream of olive oil pouring out of the centrifuge:
The oil will settle in our cellar for two months, and then be bottled: estate grown, certified organic Tablas Creek olive oil. And it is already delicious; you could smell the rich, pungent aroma of fresh olive oil from outside the winery, even though we're processing the olives in our nursery, a few hundred yards away. One more photo, because it's too good not to share: a single one of our Manzanilla olives, dipped in the oil made from the previous batch. Yum!
