Hops are an aromatic herb which give beer its characteristic bitterness, flavor, and aromatic qualities. Hops also help protect the beer against spoilage, aid clarification and head retention, and serve as a preservative. Our hops are vacuum sealed in mylar pouches and stored in the freezer until shipping. For maximum freshness keep hops in the freezer and out of light until used. Pelletized hops are mechanically processed through a hammermill and extruded into the pellet. They are held together with their own natural oils and contain no binding agents or additives. Pelletized hops settle to the bottom of the kettle and/or fermenter, therefore removal is not required. So they are easy to use. We endeavor to maintain a wide variety of the finest hops. Please indicate a second choice or be flexible in accepting substitutions when necessary. The alpha acid rating is written on each pouch.
