Can wine grapes be used for grape juice?
The juice varies by type of grape, just as with the wines that come from them. And taste is subjective, of course. Most wine grapes are picked at a lower brix level (sugar content) then juice types, but they can be picked when the sugar level satisfies your wants and needs. They still make wonderful juice. We grew Mouvedre grapes for awhile, and the juice is great. Grape juice wants to ferment, and it does so pretty quickly – about like apple juice wants to be cider. The grapes ripen all at one time. If you have more grape juice than you can possibly drink at one time, there needs to a means to store it. Freezing is a quick option, but even a barrel filled with juice can be inconvenient in a freezer. The most efficient (and some would say best) way of enjoying the juice over the next few years is to ferment it into wine.
