I dont know how far its gone at your place.... But here we harvest now. Sweden south.... When some of the flowers have tiny brown dots, its time to harvest. But i think its different to different hops too.....
Try to get in touch with a company that grow hops and ask them.... Maybe the alpha is less if u take them too soon or too late....
But some wait until just before the first frost. Im not sure if u even have frost there, but here some wait until end of september to beginning of october.
But a company here harvested last weekend. Now they are in the dryer. Its a small assosiation that grow old hops, like they did in the old days, and do it precise the same way as they did then. The same old dryer and all.
