30 YEARS OF PASSION PRODUCING PERFECTION

Stephan Diedrich founded Diedrich Manufacturing Inc. in 1980 to build the most innovative and highest quality coffee roasting equipment. Stephen was raised on a coffee farm in Guatemala; he was literally engrossed in coffee from a very young age and garnered a tremendous amount of knowledge about coffee. This knowledge consisted of both the agricultural and roasting aspects of coffee.

In the late 1970's Stephan realized that, with the growth of the small retail coffee industry and the growing consumer demand for specialty coffees, a new and improved method of roasting coffee was required. Coffee roaster technology had changed little in the past 70 years. Roasters were still using atmospheric gas burners, which did not distribute the heat evenly on the roasting drum, resulting in hot and cold spots. Roasters also did not allow for finite control of air moving through the roasting drum. These two limitations prevented the emerging specialty coffee roasters from fully developing unique coffee blends.

Stephan was, and continues to be, a pioneer in the growth of the Specialty Coffee Roasting trend that started in the United States in the early 1980's. His development and marketing of the Diedrich IR-12 Coffee Roaster in 1981 took the industry by surprise. This revolutionary model incorporated a new radical design over the more conventional roasters. The design features of this new roaster maximized the inherent flavor of all coffees. Applying the correct combination of heat, airflow and timing, the IR-12 created the optimum environment for every varietal of coffee bean. This new roaster technology enabled complete control over the roasting environment, accommodating the differences in growing altitudes, cultivation techniques and processing methods as well as bean size, density and moisture content.

With patented infrared burners and scientific heat exchanger technology that provide unsurpassed control over the roasting environment allowing roasters to maximize the distinct flavors of each bean...ultimately crafting the perfect cup. The Diedrich Coffee Roaster quickly became the most sought after roaster among the emerging specialty coffee roasters in the United States. Stephan did not stop there though; he added other new roaster models incorporating the same technologies and expanded into ancillary equipment. In 1985 he developed and sold his first industrial size roaster, thus entering a whole new segment of the coffee equipment market. In less than two decades, Stephan and his wife Becky guided Diedrich Manufacturing, Inc from its roots as a start-up in the family's garage in Costa Mesa, California, to one of the world's premier coffee equipment manufacturers.

Today Diedrich Roasters capitalizes on its industry reputation for high quality products and services. At the same time, the Company is always looking to improve the roasters performance and build quality using the best technology and innovations on the market. Making Diedrich the most eco-friendly and most efficient roaster on the market today Our future is committed to the advancement of roasting technology and original product development.
