Mauby is a Caribbean drink made by steeping mauby-tree bark with spices and sweetening the resulting infusion.
The beverage is prepared from the bark of trees in the Colubrina genus, especially Colubrina elliptica. Recipes commonly add spices such as cinnamon and clove, then sugar or another sweetener. Fermented and non-fermented versions exist, and the drink can have a distinctly bitter aftertaste.
Mauby is popular in several Caribbean countries, including Barbados, Trinidad and Tobago, and Saint Lucia. Its bitterness is one reason it is sometimes an acquired taste, while commercial versions may be sweeter than traditional homemade preparations.
Mauby is not the same as sorrel, which is made from hibiscus calyces, or sea moss, a Caribbean beverage based on seaweed and milk or sweeteners. Those drinks may appear together on Caribbean menus but use different principal ingredients.
