The first year for my Brewers Gold, and cascades, I got about 1/4 pound of hops from each. Cones did not fill in along the bine that first year.
The second year, we had a balanced rainfall summer, so cones were dense along entire bine and had a great harvest from both.
The third year year, we had a really wet summer - brewers gold did very well, but cascades not that productive.
This year, we are having a very dry summer, and I really have not been out watering the bines as I should have, other then my new Hallertau's, and grape vine I'm trying to establish. Brewers Gold are looking very good again, cascades pretty thin, and hallertau doing what I would expect first year - thin but should have enough for 1 batch.
I'm in NE PA and in a drought area this summer. It has been a very hot one as well.
