Sirem Hops

Sirem is an exquisite and rare clonal selection of the traditional Saaz family, originating as a clone of Zatecky Krajovy at the Hop Research Institute in Zalec. Known by several aliases in the international trade—including Aurum, Bohemian Red, and Saaz—it is a cornerstone of the "Bohemian Red Hop" tradition, distinguished in the field by its striking reddish stems. Due to its historically poor growth rate and low yields, Sirem remains a boutique variety grown on very limited acreage. Despite these agricultural challenges, it is prized for its historical significance and its ability to produce the "super-premium" character required for world-class, authentic continental pilsners.

The sensory profile of Sirem is the embodiment of the "Noble" hop ideal: exceptionally mild, pleasant, and sophisticated. It leads with a primary, "old-world" bouquet of soft floral notes and sweet hay, immediately followed by the classic spicy-earthy undertones that define the finest Bohemian hops. As the profile develops, brewers will find a remarkably clean and delicate bitterness that integrates seamlessly into light malt backbones. Thanks to its high humulene-to-caryophyllene ratio and low cohumulone levels, Sirem provides a rounded, non-lingering finish and a refined herbal aroma, making it the definitive choice for brewers seeking a polished and professional aromatic depth.
