Sometime around 1900, Fullers changed the name of their Strong/Stock Ale from XXK to BO, or Burton Old. Not sure why they did that. Butt they would stick with the new name for several decades.
There are a few significant differences in the recipe. The biggest being the lack of brown malt in this iteration. Instead, there’s a small amount of caramel for colour. There’s also been a small amount of flaked maize added. The majority of the base malt was made from English barley, with around a quarter from Chilean barley.
Other differences? The OG is two degrees lower. And the boil time is 75 minutes longer.
Four types of hops: Mid-Kent from the 1908 and 1909 harvests, English from 1908 and Oregon from 1907.
I’m pretty sure this would have been brewed as a Stock Ale. Being aged for at least six months in trade casks before sale. Possibly as much as a year or more.

Would a beer like this be primed or just carbonate naturally from the residual sugar in the trade casks?
ReplyDeleteIt had 173 lbs of DM primings for 164 barrels. So about 1 lb per barrel.
DeleteWere stock ales cask hopped, or was that more of a running beer thing?
ReplyDeleteI think anything meant for ageing was dry hopped.
