Let's Brew - 1869 William Younger BS Porter

Porter, the big beer hit of the 18th century, didn’t take long to spread from London, first to other parts of England and then north of the border into Scotland.

Initially it was all imported. A poem, published in a newspaper in 1774, bemoaned the money Scots wasted importing Porter from England: “Why drain our cash be-south the Tweed?” Local brewers took heed and picked up the style.

Stout was popular in Scotland right through into the 20th century, but standard-strength Porter never took hold like it did in England. By the middle of the 19th century, little of it was brewed. Making this a rare Scottish example of the style.

Most striking is the very low gravity for the 19th century. A good bit lower than in England. For example, in 1879, Whitbread’s Porter had an OG of 1050º . The grist is odd, too. There’s a surprisingly high percentage of amber malt. There’s so much that I suspect it must have been diastatic. A London Porter of this period might have contained a little amber malt, but would certainly have contained brown malt.

The hopping is very tricky on this one. All of the hops were second-hand, having already been used once in another brew. I’ve greatly reduced the quantity to take that into account. Though whether that’s really the same is open to debate. If they have them to hand, you could try using 3 oz. of spent hops instead.

Ron does the "BS" indicate that this was sold as brown stout?

Anonymous,

Younger wasn't very consistent in the naming of this beer. Sometimes it appears as P in the brewing log, others as BS. This particular brew was called both. The records span two pages: on the left page it's called P and on the right page BS.

Yes, BS would have stood for Brown Stout. Though what the beer was sold as is anyone's guess.

How can I emulate spent hops? I assume I could simmer them on the stove the night before in water or even finished beer?
