The Manhattan is one of my favorite cocktails, yet some bars make me sad by shaking this drink instead of stirring it. Overall, a good rule of thumb to follow is that if a drink consists of all alcoholic mixers (as this one does), then stirring is sufficient to mix the drink. As Robert Hess points out in this instructional video, it also makes for a much more visually appealing cocktail. Check out this video to learn how to make an authentic Manhattan.
