So what is the proper etiquette…?
Do you tell a bartender in Manhattan, that the Manhattan he just made with pride and flare should NEVER be shaken? Or do you simply sip it and smile and enjoy? … knowing you are the wiser.
I always assumed that Bartender 101( taken at some liquid trade school) would have taught that one of the most famous cocktails shouldn’t ever see the inside of a shaker. A drink like the Manhattan needs to be stirred so you are able to achieve the appropriate coldness without interrupting the clarity of the ingredients in your customer’s class.
Side Note for other drinks: Shaking is needed when you’re using ingredients that don’t combine well without a vigorous shake.
