How Long Is Limoncello Good After It's Opened? - Tasting Table
Briefly

Limoncello, a sweet, citrusy liqueur from Sorrento lemons, is traditionally sipped as a digestif. Stored in the fridge, it lasts up to a year.
Storing limoncello in the freezer can help maintain its taste, but only for higher proof liqueurs; anything lower may freeze, affecting quality.
While homemade limoncello has a similar shelf life to commercial options, the lack of sterilization could lead to spoilage if not prepared properly.
After opening, it’s best to consume limoncello within six months for optimal flavor, as its vibrant lemon taste can fade over time.
