Pale Ale - Brewers in England were looking for a way to produce a constant paler beer. It was impossible to accurately control the heat generated in the wood burning kilns of the day and this often resulted in dark roasted or scorched barley which caused the beer to turn dark. A processed form of coal called coke was discovered which burnt hotter and more steadily, this gave a clearer, light to amber, or copper coloured ale. It was far paler than any British ales brewed so far in its time. Strengths range from 3% ABV upwards.
