Limoncello is an Italian lemon liqueur mainly produced in Southern Italy, especially in the region around the Sorrentine Peninsula and the coast of Amalfi. In northern Italy, the liqueur is often referred to instead as limoncino.

It is Italy's second most popular liqueur and is traditionally served chilled as an after-dinner digestif. It's also a well-known homemade liqueur with various ingredients added to it, such as but not limited to vodka for a little extra kick!
