I should be pleased, really. Peter Symons has been busy again getting the Amsterdamse Stadsarchief to digitise records. And he's come across something that I looked for, but couldn't find. Details of Heineken's brewing process. In the nattily=named document "Brouwjournalen van de proefziederij, met daarin tevens opgenomen gegevens van de gist- en legkelder. , 1935 - 1957".
Unlike the brewing records, it lists the brewing process in great detail. In particular, the mashing and boiling schemes. Things I had to just guess at before. Great, in the greater scheme of things. But it means that I have to rewrite all the Heineken recipes in "Blitzkrieg!".
Some of my guesses weren't far wrong. The Pis did have a double decoction, not much different from my guess. And I was correct about some numbers signifying the hop addition quantities. Which, weirdly, increase the later the addition. The timings I got wrong, however. Rather than 90 minutes, 60 minutes and 30 minutes, they were 120 minutes, 60 minutes and 20 minutes. Not so far wrong. I'm pleased that I got that close.
Beiersch is where I was the most wrong. That had a triple decoction. But most unexpected was that the kleurmout - a roasted malt similar to black malt - was added to the lauter tun around the time of the third decoction. No way I would ever have guessed that.Here are the mashing details of a test batch of Beiersch. Where they were looking at the difference between using well water and mains water.
