Imported from Italy, Pisa takes its name from the area
in which it is produced and from where its main ingredients of almonds, pistachios and hazelnuts are grown.
The packaging is designed to reinforce the liqueur's place of origin, with the slanted bottle taking inspiration from the region's Leaning Tower.
Managing director Alistair Mutch said: "There is definitely room in the nut liqueur market for a new contender. We expect to create a very strong brand
which will prove popular with modern liqueur drinkers and a serious alternative to liqueurs such as amaretto."
The liqueur will retail at £14.49 for a 70cl bottle.
A Pisa Cream Liqueur is expected to be rolled out later this year.
