How long will Cointreau last once opened?
Opened Triple Sec can last for as long as three to four years if you store it in the right condition. When it comes to liqueurs, what matters is quality. Once the bottle is open, the contents are exposed to the air and heat, which results in evaporation.
What alcohol should be refrigerated?
The rule I use is: If it's under 15% alcohol or if the base is wine, it goes in the fridge once it's open. Spirits like whiskey, rum, gin, vodka, etc. don't need to be refrigerated because the high alcohol content preserves their integrity.
