WHC Zero Hero Low / Non Alcoholic 500g is a selected Torulaspora delbrueckii yeast strain developed specifically for the production of alcohol-free or very low alcohol beers. Thanks to its extremely limited fermentation capacity, it is an ideal solution for craft brewers and homebrewers aiming to produce modern NO/LOW alcohol beer styles while maintaining balance and structure.
Zero Hero is maltose- and maltotriose-negative, meaning it cannot metabolize maltose. This results in very low attenuation (16–20%) and minimal alcohol production during fermentation. Despite its restricted fermentation activity, the yeast delivers a clean and balanced sensory profile, without producing excessive esters, phenols, or off-flavours, allowing raw materials and recipe design to remain the main focus.
Its limited fermentation also helps preserve body and residual sweetness, an important advantage for maintaining mouthfeel in alcohol-free beer formulations.
Because residual fermentable sugars remain in the finished product, pasteurisation is required to ensure microbiological stability and prevent refermentation in bottle or can.
