tchuklobrau is basically correct.
My question is what's your intention? If you are just going to throw rhizomes in the ground, water, fertilize and hand pick as much as you want/need for you and your buddies to brew withh...go for it. It will be a tangled mess that every few years you will probably have to blow torch off of there, but you will have a blast.
If your intention is to raise them commercially to obtain a decent/profitable harvest, forget it.
Yes, there are dwarf varieties but they are all patented and you won't be able to touch them. Even they require about 8 ft (3 M) of height.
Any other variety will grow, reach out side ways, significantly under produce and eventually choke itself to death because it will be shooting rhizomes everywhere trying to find something taller to climb up. On top of that, the tangled mess you grow will be impossible to cut down and run through any kind of mechanical harvester, so plan on hand picking. The best estimate there is 30 to 60 minutes per bine.
At that length of row, you should be able to do 35 to 40 per row, so you are talking 17 to 40 labor-hours per row for harvest time.
