I've had a few goes at reviving old beers, and experimenting with how old beers might have been. One thing I have in common with Pope's Yard is that we've both had a go at reviving Benskin's Colne Spring Ale, though they've done a much better job of it than me.
There's a shrine to Benskins at one end of the brewery, complete with bottles of Colne Spring Ale...
... and the Journal of the Brewery History Society
The Business end of the brewery is a small German kit...
...with a smaller pilot plant for good measure:
My researches into Colne Spring Ale involved emailing a few libraries and collections which was sadly fruitless, so I based my version on an analysis Ron posted. Geoff at Pope's Yard did considerably better by physically looking through old records. Amongst some documents on brewery properties he found the Rosetta stone of Benskins: a booklet detailing how their beers were made.
Geoff and Ben were excellent hosts and I look forward to seeing where Geoff's recent research into ancient Sumeria via Burma takes his brewing.
