The Gibson is a mixed drink made with gin or vodka and dry vermouth and often garnished with a pickled onion. In its modern incarnation, it’s considered a cousin of the more-ubiquitous martini, distinguished mostly by garnishing with an onion instead of an olive. The Gibson is a popular drink that has been around for over a century.
