## Notes

Guinness Draught is an iconic stout from Ireland.

Guinness has a "tang" that is difficult to replicate. The recipe suggests fermenting 19 ounces of wort (for 5 gallons) with lactobacillus and brettanomyces. This should be gently heated to 160F (71C) for deactivating these organisms, then add to the main batch before packaging.

Irish ale yeast is recommended. Other English ale yeasts are possible substitutes.
