Dr Pepper has such a complex flavor profile, with a base of black cherry, vanilla, and citrus layered with spicy notes of black pepper, anise, ginger, and cardamom. The rich, sweet, and tangy base combines with spicy and almost savory notes from the spices for a literal flavor explosion that covers nearly every major taste category. The best part is that no one flavor regins supreme.
The true recipe calls for bourbon with water and sugar - or simple syrup - plus bitters (traditionally Angostura). Enhanced by a garnish of an orange slice or peel and a cherry, the finishing flavor profile deftly balances bourbon's subtle boozy heat, woodiness, and sweet, spicy notes of caramel, vanilla, baking spices, and tobacco with a complementary combo of sugar's straightforward sweetness and the spice and bitterness of the Angostura bitters.
