Deb Hatcher knows wine like she knows the alphabet.

For over 14 years, she and a few friends have run Oregon’s largest winery, A to Z Wineworks.

The company is somewhat unique in that instead of sourcing grapes from one or two so-called “single-origin” vineyards, A to Z Wineworks has worked with over 100 vineyards using biodynamic or organic farming principles in order to create its blended wines.

According to Hatcher, blended wines make up some of the most underrated bottles on the shelf. They offer the complexity and breadth of several wines, without the price tag.

“People think single-origin vineyards are the end-all-be-all,” Hatcher tells Business Insider during a retreat for companies honored by Best for the World, an annual list that celebrates businesses that use sustainable practices and serve as a force for good.

The A to Z Wineworks Oregon Pinot Gris is a ripe and juicy blend formed from 40 vineyards’ grapes. The company boasts of its “exuberant aromas” and lush fruit underpinnings. It comes with a price tag of $15, which is roughly two to three times cheaper than single-origin bottles.
