Americans love Mexican beer. Much of that beer consumed by los norteamericanos at tailgates, parties, wedding receptions, happy hours and elsewhere bubbles to life at one of the world’s largest breweries—the sprawling Compañía Cervecera de Coahuila plant—on the outskirts of Piedras Negras, Mexico.

Piedras Negras and Eagle Pass, Texas, are twin cities that lie either side of the Rio Grande. It takes lots of natural gas to run a modern brewery and the plant, owned by Constellation Brands, has an advantage over competitors. It’s located at the western end of Texas’ big Eagle Ford Shale play.
