TD-9 is a proprietary red blend of Cabernet Sauvignon, Merlot, and Malbec that celebrates a bold move. In 1973, in the space of a few months, John Shafer went from riding morning commuter trains in Chicago to teaching himself to drive a TD-9 tractor in our Napa Valley vineyard. He’d never grown grapes or made wine in his life. That spirit of risk-taking and adventure still guides Shafer today and inspired the creation of this wine.
