Grape sugar is Glucose and Fructose (grape sugar) but Sucrose is produced in the leaves. John Paul explains how sucrose is cleaved into glucose and fructose in the plant and how this helps to explain the result on flavors in the final wine.

John Paul of Cameron Winery produces wines in Oregon from, among others, his “Clos Electrique” vineyard site. We filmed with John Paul at Storyteller Wine Company in Portland and at the winery.
