アロマプロファイル
Rich and complex aroma with balanced fruit, floral, and spice notes. Combines ethyl caproate (fruity) and isoamyl acetate (banana).
発酵の特性
Foamless (awa-nashi) variant developed for practical brewing advantages. Eliminates foam overflow without sacrificing aroma quality.
概要
A foamless yeast that produces both ethyl caproate and isoamyl acetate in balanced proportions. Foamless yeasts (awa-nashi) are a significant practical innovation — traditional yeasts create thick foam caps during fermentation that can overflow tanks, requiring constant monitoring. K-15 eliminates this problem while maintaining excellent aroma production, making it popular for breweries seeking both convenience and quality.
