1000 US beer barrel (BBL) twin-stream brewery

1000 us bbl Twin Stream Brewhouse

Briggs of Burton’s Brewing team provided processing engineering design and specialist brewing equipment to the $300 million expansion in 2007. This made the MillerCoors Shenandoah Brewery, located in Elkton, Virginia (Shenandoah Valley), one of the most modern large-scale breweries in North America.

Briggs of Burton engineered a complete twin-stream Brewery, each stream being capable of 1,000 US BBL x 10 Brews Per Day (BPD), allowing MillerCoors to brew up to 8 million us bbl of beer a year. Shenandoah Brewery is notable for producing MillerCoors biggest brands including: Coors Light, Miller Lite, Blue Moon Belgian White Ale, Miller High Life, and Keystone Light. Shenandoah Brewery is a world class operation with improved product quality and consistency obtained at a lower production cost.
