I got 13 oz wet from my first year Cascades - I dried them down to around 3.5 oz and used them all (along with a few dozen cones of Magnum and Santiam first year plants) in a pale ale, and was disappointed with the final flavor and aroma. Some of the cones had started turning brown and most had a decent aroma when I tore them open, but the flavor didn't come through in the beer. I ended up boiling a hop tea to add a little IBUs to the beer post fermentation, and then dry hopped with an ounce of Cascade and Centennial pellets to add some flavor to the brew.
I guess what I'm saying is to have some commercial hops on hand in case you don't get the flavor you are expecting from your home grown hops. I'm attributing the lack of flavor to being first year hops, as it seems to be a common problem to growers. It tasted more 'hoppy' in the kettle, but after fermentation (WLP007) it was kind of bland. It could be user error on my part too, but I don't really know for sure. Regardless, it was a fun experiment and I'm hoping for better results next year. Maybe I've just burnt out my taste buds from too many high IBU IPAs and I can't taste pale ales anymore...
