Eiffel Tower XO is a well-rounded brandy with a smooth finish. It comes in a special Eiffel Tower shaped glass bottle, making it a great gift. Courriere XO, from the manufacturer Distilleries de Matha in France, is an excellent brandy with a taste of sherry due to its maturation in oak barrels where sherry used to rest. Its aroma and taste are filled with fruity tones and a subtle note of caramel sweetness.
