 Historian Luis Alberto Sánchez writes that , after Morris closed his bar , some of his bartenders left to work in other locales . Bruiget began working as a bartender for the nearby Grand Hotel Maury , where he continued to serve his pisco sour recipe . His success with the drink led local <unk> oral tradition to associate the Hotel Maury as the original home of the pisco sour . As other former apprentices of Morris found other work , they also spread the pisco sour recipe . During the 1930s the drink made its way into California , reaching bars as far north as the city of San Francisco . By at least the late 1960s the cocktail also found its way to New York .
