Description
A Saccharomycodes ludwigii for non-alcoholic and low-alcohol beer: it cannot use maltose or longer sugars, so it stops early by design. Jasper publishes about 20% apparent attenuation, which falls below the range this field allows, so the figures here are representative. A low-ABV beer is far more vulnerable to spoilage than a normal one, and post-fermentation pH correction and pasteurization may be needed for a shelf-stable product.
