What each ingredient does

Fruit juice: Adds liquid volume and fresh fruity flavour, with natural acidity that brightens the drink.
Sugar syrup: Adds sweetness that balances the sourness of the juice and smooths the drink.
Brandy: Provides the base spirit, adding warmth, body and a deep aroma.
Maraschino: Adds a sweet, cherry-like, almond aroma that layers over the fruit and spirit.
