Yeast: May 4 Use a high ratio of chloride to sulfate in your water treatment. Use a single-temperature infusion mash. The Alchemist and Odd13 recommend slightly elevated mash temperatures to promote body, but Weldwerks mashes on the low end to accommodate a lower-attenuating yeast strain, usually around 148–149° F (64–65° C). Odd 13 recommends including high-protein grains like wheat and oats. Weldwerks includes over 20 percent flaked wheat and flaked oats in the grist for Juicy Bits.
