Irish cream is an iconic Irish drink that has long been a favorite of many. It can be enjoyed straight or as part of a variety of cocktails and desserts. Whether purchased in stores or made at home, it is important to know how long homemade Irish cream lasts so you can enjoy it at its best without worrying about spoilage. Homemade Irish cream will last up to two weeks if kept refrigerated and covered tightly. However, the flavor quality may diminish after a week, so it’s important to use homemade Irish cream within this time period. When storing homemade Irish cream, make sure to keep it away from direct sunlight and other sources of heat as this will cause the mixture to break down faster. Additionally, never store any alcoholic beverage at room temperature for more than two hours; always keep it refrigerated when not in use.
