The 13th release in our 15 beers series was brewed in 1999. We found a shilling sitting on the counter of our homebrew supply store one day and had no idea how it got there. We joked around that it was a sign to brew a Scottish Ale because the strength of them are based on shillings. We soon came to realize we were meant to brew our version to be "one" more than the traditional 90 shilling
