That was indeed an excellent article.
One of the pioneers in the research and recreation of historic beers is the English Durden Park Beer Circle. This group focuses on the period from early 1800's until just before WW 1.
Michael Jackson wrote an appreciative article in 1992 which is at
www.beerhunter.com. (search Durden Park on the site and it comes right up).
The group was founded by a materials chemist, Dr. John Harrison, whom I believe is still active in the group.
It has a website which describes well its activities, see
www.durdenparkbeer.org.uk
A number of recipes used by the Circle are reproduced on the site, e.g., an 1850 Porter, an 1880 bitter beer, and so forth. In some cases taste notes are given.
One point I found interesting is the stress laid on the need to mature these beers, often from 1-3 months or more, to show at their best. It is said many of the historical breweries probably sold the beers too young but experience has shown the best beers would have been well-matured. Of course, they are talking about cask- or bottle-conditioned beers.
It is a real pleasure to see such devotion to a period of British brewing history whose greatness can hardly be exaggerated.
I love the story in Jackson's article that Dr. Harrison offered in 1976 an 1850-recipe Porter to an 86 year old woman, describing it as "like Guinness". After tasting, she responded, "This isn't Guinness, this is London Porter, I used to drink this when I was in service".
Can there be better evidence of the accuracy of the Durden Park Beer Circle's work...?
