Pearl Brewing Company
The Pearl Brewing Company (also known as the Pearl Brewery or just Pearl) was an American brewery, established in 1883 in Downtown San Antonio, Texas, USA. In 1985, Pearl's parent company purchased the Pabst Brewing Company and assumed the Pabst name. In 1999, the Pabst Brewing Company began transferring its production to Miller Brewing, on a contract basis, and closing all of its breweries. Pearl beer is still in production at Miller's Ft. Worth, Texas facility, but the Pearl Brewery in San Antonio was closed in 2001. Since then, the former brewery was purchased by Silver Ventures, Inc., which has made the property the crown jewel in revitalization efforts of southern Midtown and northern Downtown San Antonio.
Pearl Brewing Company
It is not uncommon to see beers named after the towns where they were brewed. For example, Texas' own Shiner is brewed in Shiner, Texas. 
So, seeing a local brewery name a beer after the town or city is pretty common. However, what is not common is a town named after a beer. That is exactly what happened, though, in Texas with Pearl. In a small community just west of Yoakum, Texas, a small store had the highest Pearl beer single-point sales for a number of years prior to Prohibition. Walter G. Hagens' general store was the focal point of the community, and it had sold Pearl's beers by the truckload and still sold a rather large volume of the Prohibition-era nonalcohol Pearl. The idea to name the town after Pearl was concocted by Hagens and the local Pearl distributor, R. J. Eslinger. In 1942, the motion passed and the German/Czech town became known as Pearl City.
