Scottish Shilling Ales in 1909

In the early decades of the 19th century, most of the beer produced in Scotland consisted of Ales. The relative strength was indicated by a shilling value, which originally indicated the wholesale price of a 54 gallon hogshead.

Often referred to as Scotch Ale or Edinburgh Ale, these beers came in a variety of strengths though the most renowned were the strongest. By the early 20th century Shilling Ales were going out of fashion, being displaced by English-style Mild Ales and Burton-style Strong Ales.

Before 1880, Shilling Ales were 100% pale malt, but after the Free Mash Tun Act of 1880, also included sugar and sometimes maize. They were hopped with a combination of American and Kent hops.

Boiling times varied greatly over time. Up until 1850, they were pretty short, usually just over an hour. By the 1890’s, three hours or more was common. This is an overview of Younger’s boiling times:

Youngers 140/- boil times
year boil time (hours)
1831 1
1847 0.83
1851 1.17
1858 1.25
1868 1.5
1879 1.33
1885 2.5
1898 3
1913 2.25


Throughout the course of the 19th century Scottish brewers gradually raised fermentation temperatures. By 1900 they were much the same as in England. Pitching temperatures varied depending on gravity. The strongest were pitched at 58º F, the weakest at 61º F. Raised fermentation temperatures had reduced fermentation times considerably. In “Scottish Ale Brewer” (by WH Roberts, published in 1847) a pitching temperature of 51-52º F and a fermentation time of two weeks is given as typical. As you can see from the table below, by 1898 it was less than a week:

With brewers like Younger increasingly concentrating on their numbered Scotch Ales (No.1 and No. 2), Shilling Ales gradually faded away in the interwar period.
