White Labs WLP705 Sake #7 Yeast White Labs WLP705 Sake #7 is a sake yeast for brewers making rice-based sake fermentations with koji. It is not used like an ale yeast pitched into malt wort; sake brewing depends on koji enzymes converting rice starch while yeast ferments the sugars that become available through the process. Use this yeast as part of a complete sake plan that includes polished rice, koji rice, clean water, careful sanitation, staged additions, and temperature control. If you are new to sake, read through the full process before brew day so the yeast, koji, and rice schedule are ready before fermentation begins. Before you pitch Best fit: sake fermentation using koji and rice, not standard beer wort. Process match: follow a sake recipe with staged rice, koji, and water additions. Sanitation matters: keep all cold-side handling clean and controlled. Do not guess: use the current White Labs package guidance for handling and freshness. Build the rest of the sake batch with sake making equipment and supplies and sake yeast and koji.
