The British bitter has journeyed far. It has evolved. loyal to its balanced roots but more hop-forward this year's beer will be An extra special bitter amped-up to American proportions. All-British malts, all-American hops, a beer of bitter descent.

We are Natural Selection Brewing, and our beer will be descending on pubs and bars near you this July.

Natural Selection Brewing is a collaborative project between ourselves, four MSc students – Reade, Rich, Sarah and Sam – 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', and an all-British IPA, 'Mutiny on the Beagle'. The project continually evolves, and is now in its fifth year, and consistently delivers great beer.

This year’s flagship brew – an extra special bitter amped-up to American proportions, with all-British malts and all-American hops. It’s a beer of bitter descent. Golden, with hoppy citrus notes and a slight undertone of fresh blueberry and sweet malt. Malty sweetness at the beginning followed by a strong but not overpowering bitterness at the end.

ABV: 5.1%

A continuously hopped SMASH beer – Single Malt And Single Hop – using Maris Otter and Belma. The simple combination gives the fruity Belma plenty of space to show what it can do, with hops added to the mash, before the boil, every 10 minutes until flameout, and to the cask.

ABV: 4.8%

An American cream ale, with a Scottish twist. Tablet in the boil to bring milky sweetness to a classic American session ale.

ABV: 5.3%

5.4% - Reade's take on the German alt. Strong malty base with noble hops and long cold conditioning. A clean, crisp session alt.

8.3% - A wheated barley wine, pairs brightness and zest of wheat with the heavy alcohol of a barley wine.
