In a Continental Sour, which ingredient is floated on top?

• A. Bourbon
• B. Fresh lemon juice
• C. Ruby port (float)
• D. Orange zest

Answer: (C)

Layering a drink to create a distinct top note is a common technique, and in the Continental Sour the top layer is ruby port. Pouring the port gently over the back of a bar spoon lets it sit on the surface as a float, adding a sweet, fruity aroma and color without fully blending into the sour base.

The base of the Continental Sour is built from the spirit (bourbon) with the sour components (like lemon juice and sugar), so bourbon sits in the body of the drink, not on top. Fresh lemon juice is part of the sour mix, integrated throughout, not a separate floating layer. Orange zest is typically used as a garnish or to express aroma, not as a liquid top layer.
