The difference between "liquor" and "liqueur" primarily lies in their definitions and usage:

Liquor:

• "Liquor" refers to a broad category of alcoholic beverages that are distilled rather than fermented. It includes spirits such as whiskey, vodka, rum, gin, tequila, and brandy.
• Liquor is typically characterized by its higher alcohol content, which is achieved through the distillation process. It is often consumed neat (straight), on the rocks (over ice), or as a base ingredient in cocktails and mixed drinks.
• Examples of liquor include bourbon, scotch, tequila, and vodka.

Liqueur:

• "Liqueur" (sometimes spelled "liquor") refers to a sweetened and flavored alcoholic beverage that is often lower in alcohol content compared to traditional liquors.
• Liqueurs are typically made by infusing or distilling fruits, herbs, spices, flowers, or other flavorings into a base spirit, which is then sweetened with sugar or syrup.
• Liqueurs come in a wide variety of flavors and can be enjoyed on their own as a digestif or aperitif, mixed with other spirits or non-alcoholic beverages in cocktails, or used as flavoring agents in cooking and baking.
• Examples of liqueurs include Grand Marnier, Baileys Irish Cream, Amaretto, and Cointreau.

In summary, "liquor" refers to distilled alcoholic beverages with higher alcohol content, while "liqueur" refers to sweetened and flavored alcoholic beverages with lower alcohol content. Both types of beverages serve different purposes and are used in various contexts, whether for sipping, mixing in cocktails, or adding flavor to culinary creations.
