Geoff Gorsuch, our Winemaker, does show and tell on shoot thinning and suckering the vines.
Couple of terms he uses:
1. Cordon: These are, in our case, two permanent arms tied to the lowest trellis wire. The naked vine looks like a “T” formed by the trunk and these bi-lateral arms.
2. Spur: The spurs are very small protrusions in the cordon that contain the growing points (buds) for this year’s shoots. They’re hard to see, because it’s so leafy, but they’re there!
