Is Lifevine Zero Sugar Sauvignon Blanc Gluten Free?

The Ingredient Breakdown

As a food scientist, I look for hidden gluten in processing aids and flavorings. Fortunately, Lifevine keeps it simple. The ingredients listed are Organic Grapes, Yeast, Yeast Extract, Tartaric Acid, and SO₂ (Sulfites).

Organic Grapes: The fruit itself is naturally gluten-free. The concern for gluten usually arises from the soil or fertilizers, but organic certification standards ensure no gluten-containing fertilizers are used.

Yeast and Yeast Extract: Winemaking yeast is a fungus, not a grain. It is used to convert grape sugars into alcohol. Yeast Extract is a byproduct of this process, often used to enhance mouthfeel or flavor. It is derived strictly from yeast cells and contains no gluten proteins.

Tartaric Acid: This is the primary acid found in grapes. It is often added to stabilize the wine and balance the acidity. It is a plant-derived acid and is completely gluten-free.

SO₂ (Sulfites): Sulfites are a natural byproduct of fermentation and are also added to preserve the wine and prevent oxidation. They are not related to gluten.

Nutritional Value

Lifevine markets itself on being 'Zero Sugar,' which is a significant nutritional distinction. In the world of wine, sugar is often the hidden enemy for those watching their waistline or blood sugar levels.

Because this wine is fermented to total dryness, the residual sugar content is negligible (typically less than 1 gram per serving). This puts it in the same category as other dry wines like Brut Champagne or Pinot Grigio. It fits well into Keto, Atkins, and Low-Carb diets.

Regarding calories, a standard 5oz pour of dry Sauvignon Blanc usually ranges between 120 and 125 calories. Since there is no added sugar or carbohydrates from sweeteners, the caloric load comes entirely from the alcohol content (ethanol). It is fat-free and contains no significant amounts of sodium or cholesterol.
