Science of Shaking I - recycled posts


As I have posted yesterday the Agar-Agar Clarification post, I thought, that it would be also great, that I reinstate the post about Science behind shaking. Again Dave Arnold - again groundbreaking. Maybe these discoveries were even more groundbreaking as the clarification techniques.

Hence enjoy, what you will find out here...


I could say now: I’ve told you...
Obviously I won’t do [ups - ahem I just did...].
Dave Arnold and the guys at www.cookingissues.com just did an epic voyage, discovering the mechanics behind shaking.
Why don’t you read the short story below - and click the blue link for the whole post?
For those of you without patience: the Short Story
Cocktail shaking  is a violent activity.  If you shake for around 12-15 seconds (though shaking longer won’t hurt), and if  you aren’t too lethargic, neither the type of ice you use nor your shaking style will appreciably affect the temperature or dilution of your drink. Shaking completely chills, dilutes and aerates a drink in around 15 seconds, after which the drink stops changing radically and reaches relative equilibrium. Shaking is basically insensitive to bartender-induced variables.  See my post on the Science of Shaking.
Stirring is different. Think of stirring as inefficient shaking. It can take over 2 minutes of constant stirring to do what shaking can accomplish in 15 seconds. No one stirs a drink for 2 minutes, so the drink never reaches an equilibrium point. All the bartender-induced variables –  size of ice,  speed of stirring, duration of stirring, etc. — make a difference in stirred cocktails, so bartender skill is very important in a stirred cocktail.
Because stirring doesn’t reach equilibrium, stirred drinks are warmer and less diluted than shaken cocktails. Stirred drinks, unlike shaken ones, are not aerated. Stirring does not alter the texture of a drink –it merely chills and dilutes. A properly diluted cocktail stored at -5 degrees Celsius in a freezer is indistinguishable from a properly stirred one.
Don’t believe me?  The proof’s in the long story.

Basically: The technique of shaking is insignificant for the temperature and dilution of the drink; most important is the length of the shake.
However - the texture of the drink depends on the method! 
Further, it is meant, that the drink is still shaken properly and not douche_bag’gy like you can see so often.
Another important note of the story is, that stirring makes actually sense! 
There is the controversy, that you can shake drinks [which supposed to be stirred] and according to cookingissues.com this is wrong - meant to be stirred drinks, are tasting better stirred than shaken 
[I always knew this, but thank you for the confirmation].

How to use citric acid - and why you might not want to use it anyway!

To be honest, I shied away of this topic, because I think, people can misinterpret this - big time.


I don't want to be part of the problem - I want to be part of the solution! But when Chris, over at A Bar Above discussed this subject- I literally could not resist to join into "the discussion".

Here is the video:





I - however take a bit slower approach than Chris.
What is citric acid?
Chemical Compound
Citric acid is a weak organic acid with the formula C6H8O7. It is a natural preservative/conservative and is also used to add an acidic or sour taste to foods and drinks.
Wikipedia Formula: C6H8O7
Molar Mass: 192.124 g/mol
Melting Point: 153C
Density: 1.66 g/cm3
Boiling point: 175C
Soluble in: Water
Why is it controversial?
In my "mixology world" it is controversial, as citric acid is the stuff, which makes the nightmarish sour mix [preferably in powder form] sour. Yeah - citric acid is the main ingredient in one of the most controversial [and in the modern craft bartending wor…

Is Jack Daniel's a Bourbon Whiskey?

So Jack Daniels want to make us believe, that it is not a bourbon - but it meets all standards of a bourbon - only it is better?!

Half of it is true: Jack Daniels meets all qualification points for a bourbon. And yes it is true, that they add one more step - the charcoal mellowing. However this doesn't make it not a bourbon.

Well - point is, that the question is not really adequate. The answers to the rather vague question: "Is Jack Daniels a Bourbon?" is driven by semantics and interpretations.

What you could ask is: Can Jack Daniels rightly be called bourbon?
And the answer is: yes, it can. It meets all points to be even a Straight Bourbon [however please note the differentiation to Kentucky Straight Bourbon - as this is again a regional denomination, which Jack Daniels obviously doesn't meet].
The video is explaining exactly the laws. Before Jack Daniels also stated very proud, that they are sour mash. This was a bit... misleading, as most American Straight Whisk…

Secrets of Darcy - this is the best way to create sugar syrup

I am a "rich syrup guy"... not a "simple syrup guy".
This is, because it is better to be able to control dilution by yourself - not by he setup you have got.

I had also a pretty straight forward method: adding 1 kg sugar into 1/2 liter of cold water and blend until dissolved (be carefully, not to blend too long with a high-performance blender, because it would heat up).

The issue here: it takes some time - because sugar doesn't "like" to dissolve in cold liquid.

A lot of bartenders are adding sugar into hot liquid. This isn't a good idea either: due to hydrolysis the sucrose is converting into fructose and glucose. This makes the sugar thicker and sweeter - but also makes the result less consistent (as you don't meticulously monitor all details (time, temperature, pH, etc.). Further the thickness of the glucose worsen the ability of the syrup to mix in cold liquid (speak a cocktail).
