I don't know who compiled it, or why, and there is no date. But we can place it in the mid 1980s because the Alice Brewery is listed, which lasted for only five years between 1983 and 1988. Strathalbyn is also there, which closed in 1987, and Devanha, which closed in 1986; so 1983–86, which is close enough for me.
It's a list of the cask beers available in Scotland at that time, and interesting because it coincides with a time when old-established brewers were still making real ale, but the first micros were beginning to appear.
Alloa, Drybrough, McEwan's, Younger's and Maclay's are all gone. Well, Maclay's pub company still own the Clockwork brewpub in Glasgow, so I guess you can technically say they're still involved in brewing.
Lorimer & Clark are still with us under the Caledonian name. Broughton, Traquair House and Belhaven are the only other survivors.
Look at the gravities. Some brewers had 1.040 as their strongest beer.
