I don't know about hops, but deer are so bad in my garden (KY) that i have tried almost everything.... My garden is 25' X 60', and my property backs up to a large wooded area.
-Dog hair, human hair etc, didn't work for me
-Hot pepper, Mix with vingar, dish soap, etc works ok until it rains
-Fencing works but must either be a small area they can't jump into, or 6ft - 8ft tall.
-I tried a scarecrow, tying plastic bags to plants, pie pans etc, and it works for a while, but they get used to it.
-Electric fence - This was my permanent solution. While I don't like the idea of shocking the deer, it ended up being much cheaper than tall fencing, and just as effective. I bought an electric fence kit for around 40 US dollars, and bought 1/4 mile of cable for 15 dollars ( i had some old metal fence stakes laying around that i used to hang the cable- the wire was properly insulated from the post with PVC). The first night i had it up, a brave deer ventured into it, and got shocked and apparently jumped into the fence because it broke some of the cable which was laying on the ground the next day. I repaired the cable, and never had another problem. You can even run a row of the cable lower to the ground to keep rabbits, and groundhogs out.
