Let's Brew Wednesday - 1941 Barclay Perkins Export

What’s changed since last year? Just about nothing, if I’m honest. Even the gravity has remained the same.

The grist is still 28 quarters of lager malt and 9 quarters of grits. I’m pretty sure that it’s lager malt and not pale malt purely based on the name of the maltster: Gilstrap (coincidentally, from my home town of Newark). Barclay Perkins usually got their lager malt from either Taylor or Gilstrap.

One area where there have been modifications is the hopping. The rate has been reduced from 6 lbs per quarter (336 lbs) of malt to a bit over 4.5 lbs. Brewers were instructed by the government to reduce hop usage in the summer of 1941.

Two types of Bohemian Saaz were both from the 1938 harvest. In addition, there were Belgian Saaz and English hops, both from 1939. All the hops had been cold stored.

This was the mashing scheme:

mash in 110º F 86 minutes
raise to 154º F 20 minutes
raise to 168º F  
hold at 168º F 29 minutes
Sparge at 175º F  

The cereal mash was used like a decoction.

Would any of this have actually been exported in 1941? How much valuable freighter space would have gone to beer in the hopes it would make it through the U Boats, when there was such a pressing need for ammunition and provisions?

Anonymous, Export is a lager beer style, like Pilsner or Helles.

Bet that was the last year of using Bohemian hops for a while.
