Dense, stable foam that holds through the photo — and the sip. A DUEBEL foam generator for building light, airy lecithin foams to float on a cocktail. A battery air pump drives a fine stainless airstone that whips a stable foam in seconds — far denser and longer-lasting than what a stick blender throws up. Why bartenders choose it Foam that lasts. The airstone produces small, uniform bubbles that hold their structure on the drink — no collapsing before it reaches the guest. Denser than a blender. A tighter, more even foam than you get whipping by hand or with a stick blender. Fast and repeatable. Drop in the stone, switch on, and the foam builds in seconds — consistent serve after serve. Compact. Sits neatly on a garnish station. Getting started Add a food-grade lecithin to your liquid, submerge the stone just below the surface, and let the rising bubbles form the foam — skim and spoon onto the drink. Batteries are not included. Specifications Type: air-pump foam generator with stainless airstone Power: battery (not included) Learn more Read The Art of the Garnish — texture is the finishing move.
