Shouldered Cluster

Definition - What does Shouldered Cluster mean?

The shape of a grape cluster varies with each variety. The name and classification of each depend on the number of lateral branches and their length on the cluster stem. A shouldered cluster is a bunch of grapes which form a main, upside-down conical cluster with what looks like "shoulders" on the top side(s) of the bunch.
