Natural Selection Brewing is a collaborative project between students at Heriot-Watt University in Edinburgh, the International Centre for Brewing and Distilling, and renowned Edinburgh brewers Stewart Brewing.
The beer style changes each year. The project continually evolves, and in 2015 it saw the release of an American extra special bitter, Bitter Descent.
The British bitter has journeyed far. It has evolved. Now it descends upon its home, stronger and more hop-forward, but loyal to its balanced roots. An extra special bitter of American proportions. All-British malts, all-American hops, a beer of bitter descent.
