For example, substituting a walnut-infused port for vermouth in Manhattan, or using a rosemary-infused orange liqueur is a simple-yet--herbally-fabulous addition to a Margarita. And, both of those modifiers can be re-used with other cocktail creations exploding with flavor and comprised of as few as 3 ingredients in a glass. The benefit works both ways: the guest has a unique imbibing experience with homemade infusions, and if the bar is busy, the bartender is able to deliver something special without falling behind on drink tickets piling up from the waitstaff and other guests glaring impatiently for their cocktail.
