How to Ultrasonically Fat-Wash Spirits A fat-washed spirit is an alcoholic beverage infused with oil or fat. High-power ultrasound waves produce very fine emulsions and increase thereby the mass transfer between the two phases. By ultrasonic fat washing, the spirit is infused with the flavour profile of the oil and obtains thereby a unique new taste. Ultrasonic Fat-Wash Alcohol has the capability to dissolve both oil-soluble and water-soluble flavors. In fat-washed alcohol, oil or fat is used as the flavor-giving ingredient. In oils, e.g. sesame oil, and fats, e.g. duck fat, the majority of the aroma compounds are fat-soluble. With the fat-wash technique, the spirit is infused with the oil’s aroma components. Ultrasonication creates very small droplets and thereby fine emulsions. Due to the micron-/nano-sized droplets, the mass transfer between the alcohol and oil is significantly improved. A higher mass transfer means that more flavour components are transferred into the alcohol. The spirits adopt the fat’s flavor, but not its greasiness. Ingredients: 120g / 4 oz intensely tasting fat OR 240g / 8 oz (or 6 fl oz.) for less intensive fats / oil 750ml (25 fl oz.) of spirit (e.g. vodka, gin, rum) Ultrasonic Fat-Washing – Step by Step: Pour the liquid fat such as olive oil, coconut oil or bacon fat into a beaker. Add the spirit and sonicate the mixture for a very fine emulsion. Fill the liquid blend into a glass jar and let it sit at room temperature for approx. 5 min for the flavours to infuse. Afterwards, put the jar in the freezer overnight. The next day, the fat would have solidified on top of the spirit. Use a knife to make a hole through the congealed fat and strain the fat-washed spirit through a cheesecloth. Strain for a second time through a coffee filter to remove any left over fat particles. Good combinations for fat-washed alcohols are: rum and coconut oil vodka and truffle oil bourbon and melted smokey bacon fat vodka/gin and olive oil vodka/mezcal and avocado oil gin and sesame oil gin and milk tequila and buttered popcorn scotch and brown butter calvados and duck foie gras fat UP200Ht for mixology Information Request Name Email address (required) Product or area of interest Note our privacy policy.
