Can't believe it's been that long since I posted this. Anyway, to update, Frontenac and Marquette vines are both doing pretty well. I had a few pounds of Marquette's that I let sit on the vine until everything else ripened. The sugar content got to be close to 30° Brix. Yeah, it was pancake syrup. We had an interesting spring though. It warmed up enough that almost everything thought it was time to bud out. But then we got two hard freezes. Very few fruit trees are producing anything. Frontenac's, Valiant's and Marquette's had all popped to the point of a few small leaves and flower buds when the freezes hit. Of all my vines, the Marquette's suffered the worst. Valiant's worked through it without much damage at all and Frontenac's experienced some damage, but still worked through it. The poor Marquette's looked pretty sad, except for one vine that seemed to take it in stride, which was strange. The attached photo is from the morning of the hard freeze. I tried spraying some water on the buds, but that didn't work very well. Anyway, all are producing grapes now fairly well, but the ripening will be very uneven this year. I suspect birds will be relentless since that will be about all there is in the way of fruit to pick on. I rec'd an email from the Colorado State Biologist stating that bears could be a problem as well since pretty much all of their forage froze out in the high country. Oh boy!!! Could continue to be a challenging year.
