In recent years, layering has become more and more popular, like in the Black Cherry Cooler
. To layer a drink, individually pour the ingredients in a shot glass in order from heaviest to lightest. To prevent them from mixing together, carefully pour over a barspoon (or teaspoon). Because ingredients differ in density, the layers will stay separate. However, before you begin, you’ll need to know how heavy your ingredients are in relation to one another. As a rule of thumb, the lower the proof of the alcohol, the heavier the ingredient is. For instance, grenadine (non-alcoholic) is heavier than Jim Beam Black®
(86 proof/43% abv) which is heavier than Jim Beam® Bonded
(100 proof/50% abv).
