Codename : St. Paddy’s Stouthorpe 2024

To aid in celebrations of St. Patrick’s Day 2024, this stout has been prepared with chocolate speciality malts to change up the flavour just a little from the traditional coffee undertone. A little about the Irish stout.

The style evolved from London porters, but reflecting a fuller, creamier, more “stout” body and strength. Guinness began brewing only porter in 1799, and a “stouter kind of porter” around 1810.

Brew Day

  • Prepare 5.2L strike water, 149F. 
  • Add the milled grains to the bag.

  • Sanitise everything required for fermentation.
  • Cool to room temp, an ice-bath or a snowbank work effectively.
