Scotch or Scottish Ales are a class of amber coloured ale styles originating around Scotland. The different versions are generally separated by strength and named for the price in shillings of a barrel at the time the nomenclature came about. Hence, light versions are known as 60/- and stronger, export strength versions as 80/- up to 120/-. The flavour profile of these ales is typically sweet with lots of caramel and toffee flavours. Sometimes there is a smokey note that traditionally comes from fermentation byproducts of the yeast, but modern brewers sometimes use peat smoked malts to ensure a smokey background note.
