Horizon Hops

Dual: Aroma and BitteringAlpha 11.0 - 14.0%United States

Horizon is a true "Renaissance hop" of the Pacific Northwest, blending the sheer power of a high-alpha variety with the refined elegance of a classic aroma cultivar. Bred at Oregon State University by the United States Department of Agriculture in 1970 and eventually released in 1998, it is a half-sister to Nugget, sharing the same mother (USDA 65009) and a lineage that includes Brewer’s Gold and Early Green. Horizon is most famous for containing one of the lowest cohumulone levels of any hop—a trait typically reserved for European noble varieties. This unique chemical makeup allows it to deliver a firm, structural bitterness that remains remarkably clean, smooth, and free of harshness, making it a favorite for brewers who demand technical precision from their "workhorse" hops.

The profile of Horizon is a pleasant and well-balanced arrangement of classic American citrus and traditional herbal spice. It leads with a primary bouquet of sweet lemon zest and floral blossoms, followed closely by a secondary layer of black pepper, hay, and a faint, woody earthiness. Unlike aggressive or "dank" modern hybrids, Horizon is defined by its aromatic clarity and "bright" freshness. On the palate, the bitterness is incredibly transparent, acting as a supportive frame for the malt without ever becoming astringent. It is the definitive choice for brewers seeking a multi-dimensional hop that provides a polished, professional finish to everything from traditional lagers to clean, hop-forward ales.

Substitution Tip

If you can't find Horizon, the best alternatives are Magnum, Northern Brewer, Nugget, or Warrior®.
