RumChata is a creamy, spice-infused liqueur made from Caribbean rum and a blend of dairy cream, cinnamon, and other spices. It does not curdle because it contains no dairy products that can separate or sour when combined with acidic ingredients. However, due to its high alcohol content (around 35%), if RumChata comes into contact with strongly acidic substances such as citrus juice or vinegar, this could potentially react in the same way that adding lemon juice to milk would—and cause it to curdle. So while it theoretically may be possible for RumChata to curdle if exposed to certain types of acidity; however most recipes will tell you not to use any type of acidic ingredients when preparing drinks with it.
