Why Buy Keto
Lifevine carries the Clean Label Project Purity Award — independently lab-tested for 200+ contaminants — and every wine is Zero Sugar* per 5 fl oz serving, which is what makes it a fit for keto and low-carb diets. Here's what that means for your glass, and what to check before trusting any wine's "keto-friendly" claim.
What Makes a Wine Keto-Friendly
Keto diets restrict carbohydrates, and residual sugar is the main carb source in wine. A wine is fully fermented when the natural grape sugars convert completely into alcohol during winemaking — nothing is left over, and nothing is added back. That's what "zero sugar" actually verifies: not a diet trend, a fermentation result you can measure.
Lifevine's Keto Profile
Every Lifevine wine is independently tested and verified to the same standard, per 5 fl oz (148 mL) serving:
- Total sugars: 0g
- Added sugars: 0g
- Total carbohydrate: ≤ 2.5g
- Calories: ~120
These aren't estimates or category averages — they're confirmed vintage by vintage through independent lab testing, and printed on every label.
Verified, Not Just Labeled
Most wines aren't required to disclose nutrition facts, ingredients, or lab testing at all — there's no federal requirement for it. That means a "keto-friendly" or "low-carb" claim on a wine label can be entirely self-reported. Lifevine takes the opposite approach: every wine is purchased off the shelf and sent to Ellipse Analytics, an independent, ISO 17025-accredited laboratory, and tested for 200+ contaminants — including sugar content — every batch, every vintage. Wines that place in the Best Third of every wine the Clean Label Project has tested earn the Clean Label Project (CLP) Purity Award.
Frequently Asked Questions
Is Lifevine wine actually keto-friendly?
Yes. Lifevine wines contain 0g of total sugar and no more than 2.5g of total carbohydrate per 5 fl oz serving, verified through independent lab testing — well within typical keto macro guidelines for an occasional glass.
Does zero sugar mean fewer calories?
Generally, yes. Because the sugar is fully fermented rather than left in the bottle, Lifevine wines run lighter in calories than off-dry or sweeter styles — around 120 calories per 5 fl oz serving.
Will a keto-friendly wine still taste full-bodied?
Yes. Zero sugar doesn't mean diluted or watered down. Lifevine wines are fully fermented and full-alcohol, made the same way premium wines are made — the difference is what's left over after fermentation, not what's added during it.
How do I know the keto/low-carb claim is actually verified?
Look for a named independent lab, a named certification body, and a published Certificate of Analysis you can actually read. Every Lifevine wine has one, linked on the Standards page and accessible via the QR code on the bottle's neck tag.
