Barclay perkins Lager water treatment in 1934

Another title timesaver.

Compare an contrast this with Barclay Perkins' water treatment for their other beers. Very, very different.

Here's what it says for the mentally-thrabbed:

"Export & Draught Boil nos. 4 & 5 backs for 1.5 hours and alow if possible to cool to required temperature. No Gypsum added.

Dark Liquor not boiled, raise to required temperature, no Gypsum added."

That reminds me. There's a post about Barclay Perkins' water treatment I've had lying around, unfinished, for months. I really should finish it. It contains full instructions for reconstructing their water profile for each of their beers.
