O'Brien Estate is located in the Oak Knoll District AVA. Our vineyard consists of 33 planted acres of Cabernet Sauvignon, Merlot, Cabernet Franc, Chardonnay and Sauvignon Blanc. Each block is organically farmed and sorted to showcase its unique terrior and microclimate.
Through sustainable farming methods, we can produce wines that consistently express bold, rich and individual personalities. With this attention to detail and high level of integrity, our grapes can produce wines that can be enjoyed now or cellared over time.
