Comet hops are a classic American hop variety that has been around for several decades, known for their unique aroma and flavor characteristics.

Here's an overview of Comet hops:

1. Origin: Comet hops were originally developed in the United States in the 1960s. They were created through a crossbreeding program that involved several hop varieties, resulting in the emergence of Comet as a distinct hop variety.

2. Aroma and Flavor: Comet hops are known for their strong and distinctive aroma, which is often described as wild American or "dank." They can impart intense aromas and flavors of citrus (especially grapefruit), resin, and earthy/spicy undertones. The combination of these characteristics makes Comet hops stand out, offering a unique flavor profile that can add depth and complexity to beers.

3. Alpha Acid Content: Comet hops typically have a moderate to high alpha acid content, usually ranging from about 9% to 12%. This means they can contribute significant bitterness when utilized for bittering additions in the brewing process.

4. Usage: Comet hops can be used at various stages of brewing:

   • Bittering: Due to their alpha acid content, Comet hops are suitable for adding bitterness to beer when added early in the boil.
   • Flavor and Aroma: Comet hops can also contribute to the beer's flavor and aroma profile when added later in the boil or during dry hopping. They can provide a unique citrusy and earthy character to beers.

5. Cultivation: Comet hops were historically grown in various hop-growing regions in the United States. However, their popularity has fluctuated over the years, and their cultivation has become less widespread compared to some other hop varieties. Still, they remain available and are cultivated by some hop growers.

6. Popularity: While Comet hops may not be as widely used as some other hop varieties, they have a dedicated following among brewers who appreciate their unique and intense aroma profile. They are often sought after by brewers looking to experiment with different hop flavors and create beers with a distinct character.
