Question: I've recently heard about dealcoholized wine and I'd like to try some because I don't want to drink alcohol. I know that red wine can be good for you, but how much of that is due to the alcohol and how much is due to the other stuff in the wine? How is the alcohol removed and is it still good for you?

Answer: Dealcoholized wine is regular wine that's had almost all the alcohol removed. There may be a tiny amount left, but it's less than half of one percent by volume. That's small enough to officially be called alcohol-free. So even though it doesn't have all the alcohol of regular wine (around 13-14 percent), it should have about the same amount of polyphenols that are the natural plant chemicals found in the skins of grapes (as well as other fruits, vegetables, nuts and seeds).

These chemicals act as antioxidants that may protect your cells from free radical damage. Red wines have more of these polyphenols than whites because the grape skins are removed before making white wines.

A number of epidemiological studies have found a correlation between drinking small to moderate amounts of red wine with fewer deaths due to cardiovascular disease. The alcohol may play some part in the protection, but scientists believe the antioxidant properties of these polyphenols are the main reason for the potential health benefits. They include:

  • Myricetin
  • Kaempferol
  • Quercetin
  • Catechin
  • Epicatechin
  • Proanthocyanidins
  • Anthocyanins
  • Gallic acid
  • Caftaric acid
  • Caffeic acid
  • P-coumaric acid
  • Resveratrol

There aren't any studies that indicate drinking dealcoholized wine will reduce your risk of any specific diseases, but there is some research on how it compares with regular red wine for blood concentrations of some of the polyphenols and how they affect some of the biochemical markers that are associated with cardiovascular disease. These studies indicate regular wine has a bigger effect, but dealcoholized wine does improve some of these markers as well.

Of course, there's more to consider than the antioxidant potential. Dealcoholized wine has fewer calories than red wine (about 1/4 to 1/3 the calories, according to the wine makers), and you won't run the risk of consuming too much alcohol.

Dealcoholized wine starts out as real fermented wine, but before it's bottled, it's either filtered or put through a spinning process that removes both the water and the alcohol. Next, the volume is replaced with water or a combination of water and unfermented grape juice.

How does dealcoholized wine taste? I would guess that most oenophiles would struggle with the difference because alcohol contributes significantly to the body, bouquet, and flavor of wines, both red and white. The white dealcoholized wines are a little closer to their fully alcoholized cousins, but if you love a big full-bodied Cabernet, it may take some time to adapt to the weaker flavor of the dealcoholized version. But, on the other hand, it doesn't taste like grape juice either. A dealcoholized red wine still has a hint of the tannins and it isn't as sweet as plain juice.

Please note that even though dealcoholized wine is essentially alcohol-free, you should still speak to your health care provider before consuming it if you are pregnant or have been told you need to avoid alcohol.
