With last night’s heavy frost in my area, I decided to harvest the Frontenac and Prairie Star grapes this morning. The temps were in the upper 20s (F). All told, I picked 22 lbs of Frontenac and 8 lbs of Prairie Star grapes (one vine). Earlier I had picked 14 lbs of Valiant grapes. I spent some time before work sorting, crushing and sulfiting. The Frontenac went into my larger primary and the Prairie Star into a smaller backup primary. I covered the primaries and will let them sit until this evening.
