Growing hops

Last year I planted 4 hops plants. This year, I have planted 4 more. They are growing well, even though we recently had 2 frost nights. Hopefully, I will get a little hops this year so I can make a small batch with home grown hops. Unfortunately, the shop did not know what kind of hops it is. I just have to wait and see the flowers...
Below is a picture of my hops tower.
