Let's Brew Wednesday - 1915 Courage Porter

Like all London Porter breweries, Courage brewed a range of Porter and Stout. We’re going to step through the set from 1915.

Don’t expect hugely differing recipes. That’s not the way breweries worked. They operated in a much simpler way. Through parti-gyling they’d spin several different-strength beers from a single recipe.

In addition to the classic pale, brown, black malt bend, there’s also some sugar. I’ve guessed No. 4 invert, as that was the type usually intended for Stout. In the brewing record what it says is Sacc. SM. My money is on that standing for “Stout Mix”. Which would definitely imply something along the lines of No. 4.

The gravity of 1050º is about typical for a pre-WW I London Porter. Early in the war, not much changed.  And this was brewed in March 1915, less than one year in.

Would the no. 4 invert be a dark syrup (a shade darker than the #3)?

I’ve been feeling the need to brew another dark beer recently. I’m going to try this recipe

yes, No. 4 is the darkest invert syrup, 300 SRM compared to No. 3;s 70 SRM.
