This can appeal to health - conscious consumers who are looking for ways to increase their antioxidant intake.

In traditional herbal teas, Rosemary extract can be added to enhance the herbal flavor profile. It can be combined with chamomile, peppermint, or other herbs to create unique blends.

Tisanes, which are non - caffeinated herbal infusions, can also benefit from Rosemary extract. It can add a refreshing and slightly bitter note to these drinks, making them more interesting and complex in flavor.

In fruit juices, Rosemary extract can be used in small amounts to add a different dimension to the flavor. For example, in apple juice, a touch of Rosemary extract can create a more sophisticated taste, with the herbal note contrasting with the sweet apple flavor.
