Nocino is an Italian liqueur that is prepared with a maceration of unripe green walnuts in a combination of alcohol and sugar, with the occasional addition of spices, predominantly cinnamon and cloves. The process results in a dark, almost syrupy drink, with a slightly bitter, strong walnut flavor.
Though it is found throughout the country and the Swiss Ticino canton, the liqueur is traditionally associated with Emilia-Romagna, where it is usually prepared on the Festa di San Giovanni, celebrated on June 24th. Nowadays, nocino is frequently factory produced, though the homemade varieties are still held in high regard.
