Cuba is running low on beer thanks to a recent upsurge in tourism.

This as relations between the socialist country and the United States have begun to thaw.

Reports are that the increase in tourist traffic has put a strain on Cuba’s bars, cafes and gas stations which are struggling to keep up with the demand for a cold brew.

Mayle Gonzalez, a sales executive at the Cerveceria Bucanero brewery said the company needs a new plant to keep up with the demand from tourists and a burgeoning private restaurant sector that competes with state-run outlets for supplies.

Bucanero manufactures Cuba’s most widely consumed brew, Cristal, in addition to its signature brand. The company is a government joint venture with the world’s largest brewer, Belgium’s Anheuser-Busch InBev.

A record 3.5 million tourists visited Cuba last year, up 17 percent from 2014. American visitors rose a whopping 77 percent to 161,000 and the numbers are set to increase as Carnival cruise line launches its inaugural sailing of the to  704-passenger MV Adonia through its new brand Fathom starting on May 1.
