Check out the Grapevine area.
Also, good wine stores.... Locations are Shops of Legacy in Plano (Tollway/Legacy) Lakeside Shoopping Center in Plano (Spring Creek/Preston, S&K Beverage has a great selection Plano (75/Spring Creek), Goody Goody and Sigels in Addison.
Our favorites are a great Merlot. Sterling makes some good ones from an everyday bottle around $13 to the nicer bottles upwards of $50.
Grapevine and McKinney may have the local flavors you are looking for.
Happy shopping and tasting!!
