Now here’s a really weird one. A Heineken attempt to clone Dortmunder Union Export. Not for sale, but as a Christmas beer for their employees. They didn’t brew a huge amount of it, just 15.9 hl, as it was pm their pilot plant. No idea why they picked this beer to imitate. Though DUB Export was pretty popular in Germany at the time.
There’s not much to the grist. Well, at least I don’t think it is. There are four different types of malt, most of which I assume are pilsner malt. Though I’m not totally sure. Two are described as “Tcheco”, which must be an abbreviation of “Tchecoslovakia”, which is Dutch for Czechoslovakia.
Another is described, rather enigmatically “B.”. My first thought was broeimout. But that would make the colour too dark. After fiddling around in BeerSmith a bit, I found pale Munich malt gave the right colour. Perhaps it stands for “Bavaria”.
The hops were all Roudnice from the 1956 harvest. Roudnice being a town between Prague and Usti nad Labem. I’ve assumed that they’re something like Saaz. I’ve increased the quantity by a third as the alpha acid content is listed as 5% in the brewing record.
300 gms. of gypsum were added to the brewing water.
Lagering lasted 60 days.
