How is Coffee Royale prepared in terms of mixing ingredients?

Coffee Royale is prepared by stirring the ingredients together. This technique is typically used for drinks that feature a combination of liquids which do not require aeration or the addition of ice, preserving the integrity of each ingredient's flavor. In the case of Coffee Royale, which usually consists of brewed coffee, a spirit like Irish whiskey, and sometimes cream or sugar, stirring ensures that the flavors meld together smoothly without introducing air or overly diluting the mixture, which could happen if it were shaken or blended.

Stirring is also favored in cocktails where the balance of flavors is a key element, allowing the bartender to maintain control over the final taste and texture of the drink. The careful incorporation of the ingredients results in a harmonious flavor profile that is characteristic of this particular beverage.
