Here are the materials from last night's dry hop event.

List of hop varieties with parentage, age, descriptors, and commercial examples The spider plots, along with much more information on the process, were from the The Hop Chronicles project from the good folks at Brulosophy. Most of what I know about hops I learned from Stan Hieronymous's book, For the Love of Hops. Specific varietal information can be found at Yakima Chief-Hopunion and John Haas. The hops we tried last night were sourced from either Yakima Valley Hops or Hop Heaven. I've ordered from Ted (Hop Heaven) on several occasions and been very happy. This was my first order from YVH, and I can say I'm also pleased with their product.
Happy hopping!
