What is Irish Cream?

Irish cream is an emulsion liqueur: Irish whiskey (and sometimes other spirits), pasteurized cream, sugar, and flavorings such as cocoa and vanilla, homogenized so the dairy remains stable in alcohol. Baileys Irish Cream, launched in 1974 at 17% ABV, is the reference bottle and the origin of the commercial category. It is not equivalent to pouring whiskey and cream separately.

It will curdle in contact with high acidity. It is a dessert and coffee modifier, not a substitute for dry whiskey in a sour or Old Fashioned.

Sweet cream, cocoa, vanilla, and a little whiskey heat. It is a dessert modifier. In coffee it recedes pleasantly; in a citrus sour it can curdle.

It does not taste like Irish whiskey served with cream. The sugar, cocoa, and emulsifiers are part of the liquid.

Baileys was developed for Gilbeys of Ireland (R&A Bailey) and introduced in 1974. The technical problem it solved was keeping cream stable in a bottled alcoholic drink. Competing Irish creams followed.

Cocktail use is almost entirely late twentieth century: poured in coffee, in frozen drinks, and in creamy builds such as a White Russian variation that replaces plain cream with Irish cream.

Refrigerate after opening and use within the producer’s window, often several months. Build or shake with coffee, chocolate, and other low-acid partners. In a White Russian, Irish cream can replace the cream and some of the sweetness, which makes a richer, more confectionary drink than vodka, coffee liqueur, and plain cream.

If a recipe lists cream and whiskey as separate ingredients, substituting Irish cream changes both dairy fat and sugar. Do not treat it as a whiskey.
