Shaken or Stirred? There are a few differences between shaking and stirring martinis. A stirred martini will achieve temperature of about 40 degrees F. Thats a pleasant temperature at which to drink martini. The shaken martini however reaches a frosty 29 degrees F, below the freezing point of water. Second, the bartender will not give you extra liquor to make sure the glass is full! The melting ice from being shaken provides extra liquid volume so you can enjoy your martini just a little longer, even though it’s technically watered down. Consequently stirring renders a 60 proof drink whereas shaking provides 45 proof. Same amount of alcohol, but it lasts longer. Third, shaking is healthier, as shown in this scientific study. It demonstrably shows that the antioxidant levels are significantly improved. Wow! Who knew?! Thanks American Bartenders School for the shaken and stirred knowledge!
