From the Dutch's website: 
Handcrafted in small batches using botanicals popular in the 18th century, the main ingredients are wild American Spicebush and Kinnikinnick leaf. We draw flavors from around the globe to complete our recipe such as Hungarian angelica seed, Pakistani red rose petals, Gabon sandalwood, French lavender, American bitter orange peel, and Egyptian chamomile. Lastly, we add dashes of juniper, Mexican allspice, and real Ceylon cinnamon to round out the character of the spicebush. Dutch’s Colonial Cocktail Bitters have a pleasant bitterness up front, a complex spicy flavor base and floral top notes.

We proudly sell the entire Dutch's line of cocktail bitters.
