Last year was the first year and they were loaded. The vines look healthy but they didn't even bloom. None of what is already on the site seems to fit my problem. Do they only produce every other year? Thanks!

They can have an off year, but it could also be that they were pruned incorrectly, which removes the fruiting wood, or they may have contracted a virus that rendered them sterile. This article may be helpful:
