Liqueur Petrus is made in the name of Petrus Boonekamp's opera of 1777. It is distilled from rare vegetable substances picked in all the continents. Among the herbs used in the recipe you will find galingale (alpina officinarum), perennial plant originating from China and India. All the herbs used in production are essential in reinforcing the liqueur's digestive qualities.
Petrus should be drunk straight at a room temperature. Adding ice might change the taste and colour of the drink.
Alcohol consumption can be harmful. Drink moderately.
