Creating distinctive, flavorful, and visually striking garnishes is a hallmark of modern mixology. Guinness foam delivers a creamy texture and roasted, malty aromatics that can elevate Irish-inspired serves, coffee cocktails, and stout-forward signatures.

In contemporary mixology, speed matters. Not just for service, but for research and development, seasonal menu work, and rapid testing behind the bar. One technique that has become a modern standard in many cocktail programs is rapid infusion, a method that uses a cream whipper (whipping siphon) and pressurized gas to pull flavor from herbs, spices, fruits, and botanicals in minutes instead of days.
