Does “alcohol-free” wine
really contain no alcohol?

1. The practical point first: alcohol-free ≠ zero alcohol

Under GB/T 17204—2021 Terminology and Classification of Alcoholic Beverages, “alcohol-free wine” is defined as a dealcoholized wine with an alcoholic strength below 0.5% vol. Note: below 0.5%, not equal to zero. There is room inside that definition.

The same standard carries a line that is rarely noticed. In defining “alcoholic beverage”, it adds a note stating that alcohol-free wine and alcohol-free beer are included in the category. In other words, as far as the standard is concerned, these products are still alcoholic beverages, not ordinary soft drinks.

2. Dealcoholized, low-alcohol, alcohol-free: what actually differs

The three terms are often used interchangeably, but they describe different things. Under GB/T 17204—2021:

Put simply: “dealcoholized” describes the process — make the wine first, then take the alcohol out; “low-alcohol” and “alcohol-free” describe the result — how much alcohol is left afterwards.

One premise is easily overlooked. However low the finished strength, the starting point must be a genuinely fermented wine, and the base wine must be at least 7% vol. This is not the same route as blending a soft drink out of grape juice.

3. So how is the alcohol removed?

In normal winemaking, yeast consumes the sugar in the grapes and produces alcohol, along with a great many compounds that determine aroma and texture. Dealcoholization takes that finished wine and separates the alcohol out of it while trying to keep the flavour behind. Two approaches are well established:

• Reverse osmosis. Best understood as very fine filtration. Alcohol and water are drawn off together as a largely flavourless liquid; the alcohol is then stripped from it and the remaining water blended back into the wine. This is currently the more widely used route.
• Spinning cone column. A different sequence: the aroma compounds are first extracted and held aside, the alcohol is then removed, and the aromatics are blended back as required. The equipment costs more and generally only pays off at volume.

The names do not need remembering. Two things do: dealcoholization is not “grape juice in a bottle” — there is wine first, and the strength is lowered afterwards; and both methods have to blend back what was taken out, a step that is very hard to complete without loss.

4. Two questions that come up often

“There's no alcohol in it — why is it still expensive?” Because dealcoholization is an extra stage added after normal winemaking. None of the cost of the base wine is saved, and the equipment and process have to be paid for on top. The cost structure was never “less alcohol, so cheaper”.

“Why doesn't it taste like ordinary wine?” Alcohol is itself part of flavour and texture — it carries body, aroma volatility, and the warmth on the palate. Remove it, and however carefully the aromatics are blended back, the wine will not taste like the bottle it came from. That is not a defect; it is intrinsic to the category. Tasting it while expecting an identical wine usually ends in disappointment.

5. Three things to check when buying

• Read the actual strength. Don't stop at the large “alcohol-free” or “0.0%” on the front. Find the declared alcoholic strength. 0.0%, 0.3%, 0.5% and 1.0% are not the same thing — especially if alcohol must be avoided strictly.
• Read the product name. “Dealcoholized wine”, “low-alcohol wine” and “alcohol-free wine” map to different bands. They are not synonyms.
• Don't treat it as grape juice. A genuine dealcoholized wine follows the route “ferment into wine → then lower the alcohol”. It is a different product from grape juice, and it sits in a different price band.

6. What one figure of 0.5% means in our line of work

For a consumer, 0.5% may be an unremarkable decimal point on a bottle. For anyone importing wine, that figure determines which set of requirements the shipment then follows — which items must appear on the Chinese label, and how they are to be stated.

So when a product of this kind comes in for Chinese label review, our first step is never to read whether the packaging says “dealcoholized” or “alcohol-free”; it is to check the measured alcoholic strength in the analysis report for that batch. What ultimately decides how a bottle is labelled and how it moves is the number in the report, not the wording on the marketing sheet.

In closing

Dealcoholized wine is becoming more common, and that is a good thing — anyone wanting to drink less alcohol now has an option other than water. But one sentence is worth keeping in mind: “alcohol-free” means very little alcohol, not none at all.

Next time you pick up a bottle marked “0.0%” or “alcohol-free”, turn it round and look for the actual figure. For most people that costs five extra seconds; for anyone who genuinely has to avoid alcohol, those five seconds are worth it.
