Homebrew Crisp Pre-Prohibition Lager

  • High hop and corn-like sweetness
  • ABV 4.8%
  • IBU 21
  • OG 1044 SG

This Pre-Prohibition Lager recipe draws from the pre-prohibition era in US brewing history and features our Europils Malt and Flaked Maize to lend grainy and sweet-corn flavours respectively. Substantial hop additions give a moderate bitterness and the low mash temperature gives a lingering dry finish.

Mike'S TOP TIP

Torrefied Flaked Maize is pre-gelatinised so no need to have a cereal cooker, just add straight to the mash.

Malts used in this Recipe

Europils Malt

We take English spring barley with a slightly higher protein than our Best Ale Malt and the subsequent low temperature kilning produces Lager Malt with a sweet but not “malty” character. 

Lager malts from continental Europe tend to be higher in protein, have less modification and a lower SNR which means the malt then requires processing in a rising temperature programme. This is the reason that decoction and heated mash vessels are the dominant brewing system on the continent.

However, Lager has been optimised for UK brewing and so it works comfortably in a UK single strike temperature brewery or on a continental system.
