Blazing hot summers in Arizona might not conjure up the idea of wineries, but our great state actually has three unique wine-growing regions. They are Sonoita, Verde Valley and the Wilcox area.

Most of theses areas sit in 3,500 to 5,500-foot elevation range. There, vintners can find the perfect temperature to grow grapes. Not too hot, not too cold.

People have been growing wine in Arizona for thousands of years, according to the Arizona Wine Growers Association, but it wasn't until the 1980s when the wine industry in this state really got going.

Weather plays a major roll in growing grapes around the world and here in Arizona.

Heat is not the major concern, though, when it comes to growing grapes, according to Lori Reynolds with Sonoita Vineyards.

She said an early-spring frost can mean big problems for her crops. But that's not the only weather threat out there.

A big hail storm during the monsoon can shred vines and grapes that are almost ready for harvest.

Deer also love snacking on shoots and leaves, which can also damage the vines, Reynolds said.

Sonoita Region

About an hour west of Bisbee, the desert grassland near Sonoita gives way to an unexpected sight -- acres and acres of grape vineyards. These are not just any old grapes. These vines are turning out award-winning wines.  This is the first region in Arizona to earn the American Viticultural Area designation. 

Kent Callaghan of Callaghan Winery was one of the pioneers of Arizona wine making. "My parents and I planted our place here in 1990. And our first vintage was in '91." said Callaghan.

He was more of a beer drinker until his parents caught the wine bug, and he is now an internationally recognized winemaker. "We basically tend to age all of our wines in barrels for at least six months," he says showing us around the winery.

It is a mix of art and science that brings wines from the area to life. University of Arizona soil scientist Dr. Gordon Dutt opened the first winery in the area. 

Verde Valley Region

There nearly two dozens wineries  that make up this region and are located in and around the towns of Cornville, Cottonwood, Clarkdale and Jerome.  The Page Springs Cellars has a great area in the back where you can sip some wine while overlooking Oak Creek.  

Wilcox Region

Located an hour east of Tucson, this region produces 74% of the wine grapes grown in Arizona.  More than a dozen wineries operate in this region.
