How much is too much - over a winter? I have 5 vines (two year old columbus, cascade, and centennial, and first year nugget and willamette). Is one pot per week per vine too much?

more carbon will help to hold more nitrogen. So add chopped leaves, straw, junk mail, news paper, wood chips ect. But coffee is only about 2-5 percent nitrogen. so 100 pounds of grounds would add 2-5 pounds of nitrogen. Look up the nitrogen needs of your typical hops plant and go from there. The other 98 pounds will add trace minerals, carbon, and act as a mulch. If you don't mind the look there is no need to remove the filter. It is paper which is mostly carbon, and will break down over time.

Another option is to plant a nitrogen fixing ground cover like clover and then they will fix the nitrogen from the air.

It would be much better to compost the spent grounds before adding to gardening applications, to reduce any potential worry of 'too much'. people use coffee as a compost starter because of how nitrogen rich it can be. Perhaps you should just collect your yard waste, coffee grounds, spent grains, etc in a pile to be turned once or twice a week.

composting within the bed you are growing in can be fine and dandy so long as you are careful about it

+1 to using them in composting. I compost yard trimmings, cardboard, food scraps, and mainly - spent beer grains!
The grains are full of goodness still, but I'll warn you: they stink as they break down. I add sawdust to help (don't use dust from walnut wood, as it has arsenic).
