Nocino, also known as Nosen or Nozèn, is a traditional Italian liqueur made from unripe green walnuts. It is commonly produced in the Emilia-Romagna region of Italy, particularly in the towns and communes of Modena, Bologna, and Ravenna. Nocino can be found in various stores and shops in these areas, including local liquor stores and specialty food shops.

One popular recipe for Nocino involves steeping green walnuts in alcohol, typically vodka or grappa, along with various spices and flavorings such as cinnamon, cloves, and lemon zest. The mixture is then left to macerate for several weeks or even months, allowing the flavors to infuse. After the maceration period, the liquid is strained and sweetened with sugar or honey before being bottled.

Nocino has been recognized with the PAT (Traditional Agri-Foodstuffs) recognition, which is a designation given to traditional Italian food and drink products that have a long history and are produced using traditional methods. The specifications for Nocino with PAT recognition include using unripe green walnuts, macerating them in alcohol, and adding specific spices and flavorings. The alcohol content of Nocino must be at least 40% by volume.
