You should NEVER shake this cocktail…



Dave Arnold, the author of Liquid Intelligence (https://amzn.to/3QhTxOQ), has a Fundamental Law of Traditional Cocktails which states: “There is no chilling without dilution, and there is no dilution without chilling.”

Chilling and dilution are directly related. In fact, if you make two Manhattans with different sized ice, that are stirred for different lengths of time and stirred at different speeds, they will be identical once served if stirring was stopped once they hit the same temperature (meaning that they also have the same amount of dilution).

Ice melts at its surface area. Therefore, increasing the surface area will increase the rate at which ice can melt. Increasing the rate at which it melts also increases the rate at which it chills.

Stirring or shaking a cocktail increases contact with both the liquid and ice, therefore chilling (and diluting) faster. The faster the drink moves, the faster the drink can chill.

A shaken cocktail will reach equilibrium once shaken for 15 seconds – meaning that it will have minimal further effect on both chilling and the dilution of a drink.

In regards to chilling and dilution, stirring is inefficient and it will take around two minutes to reach the same or a similar temperature (and dilution) as shaking.

No one stirs a cocktail for two minutes. So, by shaking a cocktail for 10-15 seconds it will over dilute your drink.

My point is. Don’t shake a Manhattan 😉

  1. My first thought was why would anyone push back on saying you should stir it over shaking? The only reason I can think of is if you didn't have a half decent way to make a stirred cocktail, but even then, get some stuff together to be able to make stirred cocktails, problem solved.

  2. I received Liquid Intelligence for Christmas several years ago, and it's the reason I went from occasionally making a margarita to considering bartending one of my biggest hobbies

  3. Dave Arnold is technically wrong because you can absolutely chill a cocktail without diluting it, it’s just not necessarily the most time effective thing. You can refrigerate them or add whiskey stones, neither adds dilution. Technically… I’m a lot of fun at parties…

  4. Cocktails with citrus and sugar should be shaken. Other cocktails should be stirred. Shaking also gives cocktails a lighter texture, while stirring gives a richer mouthfeel.

  5. I've had my Manhattan, stirred with & without ice, shaken, on the rocks & on a block of ice. So everyway you can think of. If I make them at home I don't shake them. I used to though.

  6. You forgot option 3: served on the rocks in a rocks glass with only a swirl to incorporate at the beginning. Startsbout strong like the stirred version and dilutes to shaken strength by the end. Best of both worlds and lazier than either option here 🤣
