I harvested the hops today. There have been a few frosts, so the flowers on top and the vines had started to brown and were a bit past prime. I think the hops were at their peak about mid September. I did find that the flowers under the vine were greener. The browner flowers smelled milder.
The hops will sit out until they are dry. In about a week, I will put them in plastic bags and put them in the freezer.
