How long can you keep a bottle of fr angelica that has been opened?

Once opened, a bottle of Frangelico should be consumed within 8 to 12 months for the best flavor and aroma. Like other liqueurs, it has a long shelf life due to its high sugar content, but it can still degrade over time. Exposure to air and temperature fluctuations can affect its taste and quality. Proper storage in a cool, dark place can help preserve its freshness and flavors for a longer period.
