Does Kina l’Avion d’Or replace Lillet? Not exactly; more like compliments Lillet. While you can have a glass of Lillet all by itself, L’Avion is much too sweet for such a maneuver. The bitterness is also, correspondingly, more pronounced in the l’Avion d’Or, though it is still only moderately bitter. What is different is the scope. It would be more correct to say that it has an array of bitter flavors. When mixing, those flavors and l’Avion’s over-all robustness really stand out when you substitute this in a cocktail in place of Lillet. I think you might even find you want to adjust your proportions accordingly to take that into account. The fact that this is so clearly its own creature is to be commended, and provides plenty of room for the imagination to invent new drinks as well as showing established recipes in a different light.
