Sterling Hops

AromaAlpha 5.5 - 9.0%United States

Sterling is a masterful American aroma hop that brings the legendary refinement of the Old World into the modern era. Developed by the United States Department of Agriculture breeding program in 1990 and officially released in 1998, Sterling was specifically engineered to be a domestic successor to the classic Czech Saaz, which at the time suffered from unreliable availability.

Researchers created this "complex" variety (some might call it a high-bred mutt) by crossing Saaz (50%) with Cascade (25%), Brewer's Gold, and Early Green. This pedigree allows Sterling to possess the delicate "Noble" characteristics of its ancestors while offering the improved vigor and resin content of American cultivars. It has become a cornerstone for craft brewers who require a clean, sophisticated aromatic profile for traditional lagers, proving that domestic hops can achieve a level of elegance equal to the finest European landrace varieties.

Substitution Tip

If you can't find Sterling, the best alternatives are Liberty, Lubelski, Mount Hood, Saaz, or Santiam.
