Let's Brew Wednesday - 1935 Cairnes IV Porter

This low-gravity Porter was a relatively new beer, having first been brewed in 1933. Though it seems to have been a replacement for 6d Porter. A slightly stronger beer (1030º) that was itself introduced just a couple of years earlier in 1931.

Not totally sure of the name. It’s just scribbled into the brewing record and isn’t very easy to read.

Unless there was a whole lot of priming or addition of “heading” going on, this is pretty much a non-intoxicating beer. I’m sure that the intention was to provide drinkers with a cheap alternative. Much like the 4d Ales that were brewed in the UK between the wars.

Nothing much to say about the recipe, as this brew was parti-gyled with the Single Stout above.
