Wine production, including quality wines, continues in these areas of Mexico as well, most notably in the La Laguna region, which straddles the states of Coahuila and Durango in the northeast; this is the home of the Parras Valley, the first appellation recognized by the Mexican government. Half of Mexico’s vineyards are in Sonora.
