Final answer:
The 'B&B' stands for Benedictine and Brandy, which are blended to create a classic cocktail, often served after dinner.
Step-by-step explanation:
When someone orders a B&B, the two B's in the name stand for Benedictine and Brandy. The B&B is a classic cocktail that is a blend of these two spirits.
Benedictine is an herbal liqueur produced in France with a mix of 27 different herbs and spices, while Brandy is a spirit distilled from wine, often enjoyed for its rich, warming qualities.
The drink is typically served in a snifter to allow the aromas to concentrate and provides a digestive quality, making it a popular after-dinner drink.
