None. Lee describes Tierra's practices as "the best possible sustainable methods, leaning towards biodynamic."

Brother and sister team, Lee and Wayne James, began farming in 1980. The farm is renowned for the over 50 varieties of sweet and chile peppers that they grow and process. In 1992, James began smoking their chile peppers to make Chipotles. They begin the smoking process in August, when the chiles reach their full ripeness, and continue until the end of the harvest in December. Wayne and Lee smoke the red ripe chiles in a backyard wood burning oven, built by Wayne, for one week over a grape and fruit wood fire, which requires 24-hour tending to keep the fire going. Chipotles are used to spice up tacos, grilled chicken, meats, veggies, and tangy chocolate-brown sauces. They come pre-packaged in bulk. Chipotle powder is also available. In addition to selling at the Ferry Plaza Farmers Market, Tierra Vegetables operates both a community supported agriculture (CSA) program and a farmstand in Sonoma and sells directly to chile aficionados around the country through their website.
