Which characteristic is not a typical feature of Spanish Coffee?

Spanish Coffee is known for its combination of flavors and presentation, which includes a few key characteristics. The drink is typically served hot, providing a warming sensation that enhances the enjoyment of its rich ingredients—this focuses on the coffee's temperature as a vital characteristic.

The layered appearance is also a notable feature of Spanish Coffee, often achieved through carefully pouring ingredients like coffee, liqueurs, and whipped cream in such a way that they maintain distinct layers, creating a visually appealing drink that exemplifies bartending skill.

Furthermore, the texture of Spanish Coffee tends to be smooth, largely due to the incorporation of cream and the quality of the coffee used. This smoothness contributes to the overall rich and enjoyable experience of drinking it.

While various flavors can exist within the drink, the perception of a bitter flavor is not a defining characteristic of Spanish Coffee as it is typically balanced by the sweetness of liqueurs like rum or brandy and the creaminess of the whipped cream. Therefore, in this context, the reference to a bitter flavor does not align with the usual profile of Spanish Coffee, making it the feature that is not typical.
