Strata®, formally known as X-331, is Indie Hops’ first hop variety to be released out their breeding program. Born in 2009, Strata®is the progeny of an open pollinated Perle located at an Oregon State University experimental field in Corvallis, Oregon. From the get-go, this hop was out to impress. Between its strong disease resistance, vigorous growing habit, and complex layers of aroma, X-331 rose to the top of an impressive group of competitors.

General Trade Perception:

All experimentation points to Strata® being very versatile dual-purpose hop variety. Bittering with Strata® brings a nice balanced bitterness. Flavor and aroma additions bring out the fruity side with tropical fruit and fresh berry brightness. Brewers say that dry hopping deepens the grapefruit and dank/herbal/cannabis elements. At this point, it has been used mostly in IPAs, Pale Ales, and Session IPAs, but could work well in everything from Saisons to Lagers.
