The drive to Purisima Mountain was like taking a step back into my childhood, the curving roads at the top of this canyon reminded me of southern West Virginia, with one dramatic difference…there were vineyards on these hills. WE made this trek during the Spring Vintners Weekend, when we were lucky enough to do a Vineyard hike with Steve Beckmen at the Purisima Mountain Vineyard.
Located in the new Ballard Canyon AVA this property sits at the north end of the Canyon. From Ballard Canyon Road you drive up and around the Stolpman property to reach the 365 acre property. This estate vineyard is planted primarily with Syrah & Grenache with smaller blocks of Roussanne, Marsanne, Counoise, Mourvedre, Grenach Blanc, Sauvignon Blanc and Cabernet Sauvignon. This vineyard became 100% biodynamic in 2006 and uses a gravity fed drip irrigation system.
The elevations at Purisima Mountain reach 1250 feet. The wind, the fog, the climate all affect the grapes and I had a fascinating conversation with Steve about the “architecture” of the vineyard and how that was still evolving.
We had hiked part way up the Mountain and stopped in the shade of a large Oak tree to taste some wine, have some water and enjoy some snacks. Then Steve pulled us over to the nearest vines and showed us the process of shoot thinning that was beginning to happen all over the vineyard.
The vines here are bi-lateral cordons and they pull off the suckers and try to leave 4 evenly spaced shoots on each cordon. Sometimes you are just pulling suckers (shoots with no blossoms or fruit) and sometimes you are doing some pre-thinning on your fruit this way. The shoot thinning does a couple of things, it gets rid of the suckers that are pulling energy from the vine, it thins out the leaves to allow better sunlight and airflow through the vines and it thins your crop a little to allow your berries to be a little more concentrated. As they thin they also start to train the shoots up into the trellis system above.
