First there will be a series of Scottish Let's Brews. Some of those much misunderstood Scottish styles, like Heavy Wee and Smoked Scotch. Maybe even a Scottish Stout, if you're lucky. Shillings or numbers - which do you prefer? There are numbers 1 to 4. Then 50/-, 60/-, 80/-, 100/-, 120/-, 140/- and 160/-. Don't ask me what the difference is between the two sets. There's a big overlap in terms of gravity. And no obvious consistent difference in the hopping. But they must exist for some reason, mustn't they? I wonder how many other brewers had five different beers over 1100ยบ?
Then I'll be applying my mighty intellect to the Scottish beer analyses I've collected. Am still collecting, almost even as we speak. Seeing if I can finally identify what makes a beer Scottish. Other than a ridiculously high gravity. Wish me luck.
To kick things off, here's a table of Scotch Ales from between the wars:

You should notice something immediately. Two quite different beers being sold as Scotch Ale: one of 8 or 9% ABV and another of 5% ABV. Younger's ones explain it the best. The Stronger is their No. 1 Ale, the weaker No. 3 Ale. The latter being a beer which had been available, off and on, since I've been drinking. It may even still exist.
Then there are the Scotch Ales brewed for the Belgian market. There must have been money it, judging by the number of brewers involved.Including some, like John Smith, that were in, er, England.
That reminds me. I must go through more Younger's logs. In particular the ones from the 1930's and 1940's. Only had them for two years. A backlog of logs is building. Even though I've not harvested many new ones this year. So much information, so little time.
I am really looking forward to learn more about those underrated styles.
ReplyDeleteBesides, how should one interpret the "Acidity" column? How was that measured?
Bark, that's total acidity as a percentage. It would include both lactic acid and acetic acid.
ReplyDeleteNormal levels for British draught beer of the period were 0.04 to 0.06%.
Looking forward to the recipes! I will endeavour to brew as many as I can.
ReplyDeleteWill be a really great month! Already brewed the first one for tomorrow!!!
ReplyDeleteYes, Scottish beer from the 1940s—I might be interested in that...
ReplyDeleteGiddy like a schoolboy, I have often wondered the history of Scottish brewing from the Pattinson perspective ..game on !
ReplyDeleteBark,
ReplyDeleteAcidity was expressed "as acetic acid" and, I presume, measured by titration. These days we use pH which is much more convenient. If you want to convert the "as acetic" figue you may use this spreadsheet formula:
=LOG(SQRT(B5*A5/100))*-1
A5 is the "as acetic" figure expressed as a decimal.
B5 is the dissociation constant of acetic acid (0.0000175).
For example an "as acetic" figure of 0.12% returns a pH of 3.84.
The formula is the one I use in Open Office but I think it will work in Excel.
