Notes

Sources: Austin Homebrew Supply, BYO

Alternate yeasts OYL-005; WY 1084

Need a brett/lacto blend to make "tang"

Mash pale grains, cap sparge with roasted barley

To get that “Guinness tang,” try this. After pitching the yeast to your stout, siphon 19 oz. of pitched wort to a sanitized 22 oz. bottle. Pitch bottle with a small amount of Brettanomyces and Lactobacillus. Cover bottle with aluminum foil and let ferment. When beer in bottle is done fermenting, pour it in a saucepan and heat to 160 °F (71 °C) for 15 minutes. Cool the beer and pour and pour it back in the bottle. Cap bottle and refrigerate. Add to stout when bottling or kegging.
