Cointereau is either considered a premium triple sec or a liqueur depending on who you ask. It sells for considerably more than your standard triple sec but is also almost twice as strong as most. Uses a blend of bitter and sweet orange peels extracted and distilled with neutral ethyl alcohol (from sugar beets).
The flavor is good and can be used to make many different beverages. It is also a great gluten free option for individuals with allergies.
Cointreau makes the BEST bourbon side car cocktails. This plus maple syrup, bourbon and lemon juice is a seriously chug-able combination. Its high-quality production means that it can be drunk neat, over ice, or in cocktails.
