Liqueur Strawberry Castro. The Strawberry Castro liqueur is produced from 100% natural mature strawberry extracts, in a traditional way. The sweet, juicy, delicious and mature strawberry elevates this exuberant liqueur by endowing it with a rich flavour and texture and a dynamic aroma. The beloved strawberry illustrates delight with sensual strokes in the colour of passion. It is a necessary ingredient for the bar since it is mainly used for providing colour and aroma to cocktails. You can enjoy it straight, on the rocks or in cocktails.
