Wanting to impress a group of Napa innkeepers with a one-of-a-kind winery, Holme Grown paid a visit to Teachworth this afternoon. We were hosted by owner Joan Teachworth, a Nebraskan by way of Texas, who makes fewer than 200 cases of Cabernet sauvignon each year on her Diamond Mountain estate.

Her Cab is grown organically on two sloping, one-acre vineyards lying between 700 and 850 feet in elevation. Each vineyard has distinct soil and sun conditions, allowing her to produce three unique wines. All Teachworth Cabernet is aged for 30 months in new French Oak barrels, hand bottled at the winery, and aged an additional two years before release.
