1933 Drybrough P80/-

You can never have too many watery Scottish Pale Ale recipes, that’s what I say. But that’s not what you’re getting.

Instead it’s a full-strength, top-of-the-range Pale  Ale. Obviously, though, it being Scotland, Drybrough used the same recipe for all their beers.

You know how the standard line is that Scottish Ales get all their colour from either being boiled to gloop or roast barley? I’ve found fuck all evidence of this. Dark grains of any variety are rare in any Scottish beer other than Stout. So I was slightly surprised to discover Drybrough adding a touch of black malt to their beers in the 1930’s. I assume it’s there purely to add a little colour. Strange that they didn’t use caramel like everyone else.

Other than the pale and black malt, there’s also flaked maize, malt extract (very popular in the 1930’s) and a proprietary sugar called Avona. As I haven’t the foggiest what that is, I’ve substituted No. 1 invert. Though I could just as easily plumped for No. 2 invert.

As usual, there’s a good bit of guessing in the hops. All I know for sure is that they were all English. Making Fuggles and Golding a safe choice.

Going into compare and contrast mode, P80/- looks very much like and English 7d Pale Ale, or Best Bitter. Though most of the English examples have a much higher degree of attenuation, mostly over 80%. Though you can that Bass was stronger and not that far off the classic 1065º pre-WW I OG.

Not sure if you've seen this:

no, hadn't seen it. Quite interesting. Though the 1854 Salvator seems way too highly attenuated. An OG of 18.5 would have produced a beer of around 5.5% ABV according to the analyses I have.

Nice, I was hoping you might find it interesting. I know you like to check accuracy too so hopefully there'll be fixed copies with later editions.
