Want a really great glass of resveratrol-containing wine soon? The preservation of grapes using a new ozone technique could help prevent allergies that some wine aficionados have as well as boost healthy compounds at the same time.

In addition, this same ozone technique could be used in the wine-making process to produce healthier wines without the added sulphites, which preserve the taste in what I consider an unnatural way really -- but it's about the only way to preserve wine in that industry right now.

That is, for normally-priced wines. Some winemakers are aware that the sulphites added to their wines to allow them to age longer -- but can make their wines unpalatable to some drinkers.
