Fresh Hop ales are a style of beer only found near hop fields, they are unique to places where hops can be found growing. Most hops are picked, kiln dried, turned to pellets, vacuum packed, and frozen all as quickly as possible to preserve their flavor.
Fresh hops are different though. These hop cones go directly from growing plant to beer, skipping the entire processing line completely. Undried with all their original moisture (hence their other name of 'wet hop' beers) these hops impart a unique flavor to a style of beer only briefly available for one short time.
