Made from the skins of oranges grown in the West Indies. Until recently, this old cocktail ingredient had gone virtually unnoticed. A new interest in classic cocktails has brought it out of retirement. There are many recipes that call for orange bitters, but most notable is the “classic” Martini. Try a dash in your next Martini and you will never want one without orange bitters again. Used in the classic Martini and Pegu Club. Just a dash gives a great twist. Fee Brothers have been one of only two mainstays in the cocktail bitters world for over 100 continuous years. Opened in 1863, Fee Brothers of Rochester, New York, is in its fourth generation of manufacturing top quality bitters.
