Hersbrucker Red-Stem

Hersbrucker Red-Stem is, as I’m sure you guessed, so named due to its red stem. All Hersbruckers have red stems, but in this variety it is even more distinct. It is a clonal offshoot of Hersbrucker, supposedly with a higher alpha acid potential. Hersbrucker clones have declined in production over the years since their introduction in the 1980’s. This is mainly due to the rise of Hallertauer Tradition and Spalter Select, which exhibit much higher alpha percentages.

      Thanks for picking up that mistake Andre. Farnesene content has been updated to “Trace” amounts as per the USDA data sheet. Julian
