Carlos Alvarez, the San Antonio businessman and philanthropist who launched Corona Extra beer in the U.S. and expanded Shiner Beer beyond its humble South Texas roots, died on Tuesday. Mexico-born Alvarez, 73, leveraged an upbringing in the south-of-the-border beer industry to launch Alamo City’s Gambrinus Co. in 1986 and grow it into one the nation’s most successful beer importing and marketing enterprises. More recently, Alvarez emerged as a high-profile donor to education and the arts in the Alamo City.
