What makes grape juice so powerful?

In 1869, Dr. Thomas Bramwell Welch pasteurized Concord grape juice in Vineland, New Jersey, to create a non-alcoholic alternative to communion wine. The deep purple hue of this beverage comes from anthocyanins, a class of water-soluble flavonoids located primarily in the grape's skin. These pigments are highly sensitive to pH levels; in acidic environments they appear red, while in alkaline conditions they shift toward blue or even green. This chemical property means purple grape juice can act as a natural pH indicator. Concord grapes, the primary variety used for this juice, possess a slip-skin characteristic, where the skin separates easily from the gelatinous pulp. Because the pigments reside almost entirely in that dark outer layer, commercial extraction requires briefly heating the crushed grapes to leach the color out before pressing. This thermal extraction ensures the juice retains its signature vibrant purple shade and a high concentration of polyphenols, which contribute to its tart, astringent flavor profile and antioxidant capacity.

Born from pasteurization

Dr. Thomas Welch originally invented it as a non-alcoholic substitute for sacramental wine.

💡 When & how to use it

Because purple grape juice is naturally high in simple sugars and acidity, it works well as a marinade base for meats like pork or chicken, where its tartness helps tenderize muscle fibers while its sugars caramelize during cooking. To manage blood sugar spikes, pair a small glass with a protein-rich food like Greek yogurt or nuts, which slows the absorption of the juice's carbohydrates. Store unopened bottles in a cool, dark pantry, but refrigerate immediately after opening to preserve its delicate polyphenol content.
