Toschi Nocello
Made using unripe green walnuts and involves only five ingredients. These are steeped in alcohol for nine months and exposed to the sun. It then ages for at least 2 years in oak barrels, which gives the liqueur its intense flavour and the bright brown colour. The recipe still follows the original directions developed by the Toschi family. It was traditionally made on the night of Saint John, also known as the summer solstice.
