I have a couple 2nd year plants. I ended up cutting back the first growth about a week and a half ago. Since then it pushed up about another dozen or so bines. I then cut them back all but 5 bines today that I plan to let grow for the season.
I see you are in Denver, which means you are likely to get another frost / snow before the season is up. I recommend cutting them back immediately after the final frost so the new bines will be healthy and strong.
