Modern wine making in Arizona began in 1973 when Dr. Gordon Dutt, a soil scientist from the University of Arizona and A Blake Brophy established the first experimental vineyard on the Ignacio de Babocomari Ranch in southern Arizona.
According to Dr. Dutt, the high altitude and soil similar to that found in Burgundy, France are the keys to successful grape growing in the region. Following his experimental success, Dr. Dutt planted Arizona's first commercial vineyard in 1979 and opened the Sonoita Vineyards Winery in 1983. Today, Arizona wineries are clustered around the towns and cities of Flagstaff, Phoenix, Cottonwood, Willcox, Tucson, and more.
Tours typically last from 30 to 60 minutes per tour and they are well worth your time to check out the different ones. Each one has their own flavors, beauty, and charm to experience.
What is even more awesome is that most wineries offer free samples of their wines when you go through a tour as well. Some do more formal tasting events as well. The tours are extremely interesting and fun to do too. They aren't just there to sample the wine that you're looking forward to but are actually very informative and you get to meet a lot of like-minded people usually that are also doing the tour. It's always nice to a fellow wine lover! - Be sure to call ahead if you are planning on doing a tour at one of the wineries or vineyards though to check on availability since many of them get very busy during season.
