I like to make up a batch of this early in the day so I know it will be well chilled when the afternoon heat rolls in. The whipped cream is optional, but – as always – a delicious touch. If you like making cold coffee drinks, do get in the habit of making coffee ice cubes since they won’t dilute your drink. This tastes great made with Cinnamon Viennese coffee – in which case you can skip the cinnamon garnish. But any type coffee will do nicely. Time includes chilling.
