As you can see, the majority are Pale Ales of various strengths. Mostly the two classic variations from between the wars: 60/- at around 1039º and 70/- at 1045. Roughly the equivalent to modern 70/- and 80/-. One of the things I like about the Thomas Usher Gravity Book are the descriptions of flavour. The ones for Aitchison's Pale Ales aren't particularly flattering : "thin sweetish flavour". I wonder if this is when sweet Pale Ales came into fashion in Scotland?
Note the watery Pale Ale sold as 90/-. The practice of calling Strong Ales 90/- in Scotland is very recent. I suspect it goes back at the very most to the 1970's. I can't remember seeing a 90/- in the 19th century. They tended to go for multiples of 20: 60/-. 80/-, 100/-, 120/-., 140/- and 160/-. 90 bob seems to have first appeared after WW I and referred to a weak, bottled Pale Ale or IPA. Why they're called 90/- when they're weaker than 60/- Pale Ales is a mystery to me. If you have any ideas, let me know.
Brown Ale, as in England, had a burst of popularity in Scotland in the 1920's and 1930's. The two pre-war samples here are right on the border between a standard and a Double Brown in terms of gravity. The post-war one, at just over 1040º, is a around 10º stronger than a typical 1950's Brown Ale. With a colour of 50 EBC, it's only slightly darker than Newcastle Brown.
The beers sold as Strong Ale and Scotch Ale are probably the same beer. 1070º to 1080º is decent gravity for the 1950's and is around what most domestic Scotch Ales were in the 1930's. You'll not that both are a fairly dark brown. Those two-number colours are about 90 - 100 EBC.
I was surprised to see there's only one Stout. And that isn't even an Aitchison's beer. It's a brand from brand from McLennan & Urquhart, whose Dalkeith brewery Aitchison bought in 1955 and closed in 1958. It looks a typical low-alcohol, Scottish sweet Stout. It's a shame there aren't some other Aitchison Stouts to compare it with.
That's it for now. Unless I can find any more Aitchison-related material.
