Start by selecting a tall highball glass in which you will be serving the Piscola. Make sure the glass is clean, without the remnants of any past drinks that might taint the Piscola cocktail you are about to make.
Load the glass about a quarter of the way with ice cubes, and then proceed to pour 1.5 oz of Pisco brandy and 3.0 oz of fresh lemon juice into the highball glass. Use a stirring rod to swirl the mixture about, until all the ingredients are thoroughly blended.
Once this is done, proceed to top the Pisco-lemon mixture with 3.0 oz of Coca-Cola. Pour this in carefully – you don’t want it to foam up and overflow, as this would mess up the quantities of the ingredients you put in the glass.
Give it all a very brief stir, to mix the ingredients, and as a final finishing touch, garnish the drink with a fresh lime wedge. Your Piscola cocktail is now ready – serve chilled.
