As above . Another thing to consider is the quality of your hops. Some years, due to adverse growing conditions, the hops from certain areas aren't much chop. Also the big boys get the cream of the crop and we're left with the remains . For example last years Aussie crop didn't impress me at all , this years Aussie cascade and galaxy is exceptional IMHO.
Edit- Forgot it's 2017. 2016 crop Au hops are exceptional .
