Mount Tehama Winery is located in Manton, CA, a tiny little town near Redding. Alain Teutschmann is originally from Geneva, Switzerland. As an adult, he moved to Afghanistan where he sold Middle Eastern antiques to collectors in Europe and the US. As the political scene became increasingly unstable, he moved to Manton, where he had vacationed years before. When he first bought his property, he was told that it was only good for two things, growing Christmas trees or grapes. He grew Christmas trees until 2005 and planted his first grapes, four acres of Syrah, in 2000. His original idea was to sell his grapes to a winery but finding that difficult, he decided to open his own. Over the next several years, he planted more Syrah and Petite Syrah. He currently has 5,600 vines of Syrah and Petite Syrah over 10 acres. He produces Petite Sirah, Shiraz, and Chardonnay.

Mount Tehama has been certified by the California Organic Certified Farmers and is totally organic. No chemicals are used in fertilizing, protecting, and growing the grapes. Instead, natural remedies are used. For instance, if a pest is damaging the vines, Teutschmann will introduce another bug that preys on the harmful one. This is in keeping with his belief in not producing a mass market product but rather a clean, healthy product. He has based his small winery on making a good, wholesale product that is able to be sold at a reasonable price. His wines are sold in local stores and restaurants. The previous owner of the land farmed Christmas trees and did not use pesticides which have resulted in a healthy soil.
