Natural Selection Brewing is a collaborative project between ourselves, four MSc students – Euan, Dulcie, jonny, and tanya – 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. To date there has been a red ale, 'Finch', a summer wheat beer, 'Anorak', a New World Saison, 'Origin', an all-British IPA, 'Mutiny on the Beagle', AND An extra special bitter, 'bitter descent'. The project continually evolves, and is now in its 6th year.

We are cooking up a storm in the brewery and developing delicious recipes. more on the beer itself in just a few weeks!
