Some cocktails benefit from a vigorous shake. Others prefer a swift stir. And still others just want to chillax on some rocks.
Here's the low-down on when to do what.
Why stir? A couple reasons.
1) You want a cocktail that's clear as an alpine stream.
For see-through clarity, stir a martini or manhattan. A stirred martini has a very soft, silky texture. Shaking aerates the cocktail, which changes the texture, makes it a bit frothy. Some people like that, some don’t.
2) You want the least amount of dilution possible.
Shaking will draw a bit more water off the ice than stirring. Put another way, stirring can give you a stiffer drink.
Why shake? Again, two reasons.
1) To get a super-cold cocktail.
Shaking is good for drinks served up (without ice). A shaken martini has icy snap and a good crisp bite. Also, if you're serving a cocktail over ice and want to start with a very cold drink, shake it first, and then strain it over fresh ice. All you need are about 15 or 20 good shakes.
2) To combine ingredients quickly and thoroughly.
Cocktails with egg whites need to be shaken. Drinks with citrus juice are also good candidates. A Gin Fizz always needs to be shaken to incorporate the egg whites into cream and citrus juice -- and it requires a little extra elbow grease to mix it right.

Which is colder, a stirred cocktail or a shaken cocktail?
A shaken cocktail. The strange truth is, you can actually shake a cocktail to below 0 °C (between -5 to -7 °C).
Will shaking longer make it colder?
No. After about 20 vigorous shakes, the temperature plateaus. Any shaking after that is called exercise.
Why doesn't it get colder?
Because science. It’s complicated. This article explains it.
How long do I need to stir a cocktail to make it ice cold?
What takes 10 seconds with a shaker, requires a couple minutes of constant stirring.
Pro-tip for colder stirred drinks: Start out with a chilled stirring pitcher or pint glass. Then your ice won't have to work to cool down the pitcher as well as the liquid.
Does the type of ice matter?
Not really. But use lots of ice so there’s a lot of surface area exposed.
