To achieve a complex product and to supplement the antioxidant properties of the wine, the hawthorn fruits were added. They completed the product by maceration, so that the tonic wine got major active substances which have great medicinal value being effective in treating cardiovascular diseases. The content of polyphenols of tonic wine is about six times higher than in simple wine, the hawthorn representing a product rich in polyphenols (510.2 mg GAE/100g). Antioxidant capacity increased when hawthorn fruits were added, as they have an important contribution in terms of new product antioxidant properties. Hawthorn, honey and rosemary added extra minerals in the total dry extract. The relative density increased due to the substances present in hawthorn. The concentration of alcohol slightly increased due to the fermentation which triggers during maceration. The acidity of the new tonic wine developed here was higher, as compared to the simple wine. Higher acidity also contributed to the palatability, the new tonic wine showing a pleasant refreshing taste.
