In summary, the debate about whether or not shaking alcohol, specifically gin in an ice filled martini shaker, has any impact on its chemical makeup and flavor is still ongoing. The main difference between a shaken and stirred martini is the cooling and dilution factor, which can ultimately affect the taste. However, there is no significant chemical reaction between the liquor, ice, and air during the shaking process. The only difference between using ice colder than 0 degrees Celsius and ice at 0 degrees Celsius is the freezing point depression. The main purpose of shaking is to expedite the cooling process through heat transfer, not to cause a chemical reaction.

Is there any validity to the long debated topic of bruising alcohol, specifically gin in an ice filled martini shaker? Can gin or any other alcohol react and change it's chemical make up by this shaking? Can air introduced by the shaking react with the alcohol and affect the flavor by reacting with the aldehydes? Is there really a chemical reaction or is it simply a colloidal suspension of air and tiny ice particles?

As far as I remember, the basic difference between shaken and stir maritini is the chilled and dilution factor. Shaken method cools the martini faster and does not dilute (due to melting ice) the martini as much as a stir martini.

This will ultimitely affect the interaction of taste bud and the molecules. It is the same principle with red and white wine. Temperature will change the taste of wine.

Thank you for the insight but can you address any possible chemical reaction between the liquor, ice, and air with the kinetic energy and agitation of the shaking? I don't believe there is one however the topic is still hotly debated.

On the same topic, does ice that is colder than 0 degrees celsius interact any differently with ethanol than ice at 0 degrees celsius?

I'm pretty sure that a liquid solution of aqueous ethanol, when frozen sufficiently will simply yield ice and liquid ethanol; although this freezing point will be lower than 0 degrees (freezing point depression).

I don't believe that any of your queries pertain to chemical reactions (not any that I've heard of), air, alcohol, and water do not react significantly especially at lower temperatures...although there may be a slight pH dynamic.

Overall, iansmith hit the spot. Shaking expedites the cooling, the details are not so important...you're simply speeding up the energy distribution process. Heat (assuming a closed container) transfer is in the direction of lower temperature medium to the higher. The greater the distinction in temperatures, the faster the heat transfer. A temperature gradient as such that would exist if the martini/ice were left alone, will have a lower rate of heat transfer, enough so that the room temperature itself would have had quite a role in melting the ice.
 

FAQ: Martini Chemistry: Debating Alcohol Bruising & Chemical Reactions

1. What is the chemical makeup of a martini?

A martini is typically made up of three main ingredients: gin or vodka, dry vermouth, and sometimes bitters. These ingredients contain various compounds, including ethyl alcohol, water, and botanicals, that give the martini its unique flavor and aroma.

2. How does alcohol affect the flavor of a martini?

Alcohol is a key component of a martini and plays a significant role in its flavor. Ethyl alcohol, the main type of alcohol found in the martini, has a distinct taste and can enhance the flavors of other ingredients. It also has a numbing effect on the taste buds, which can help balance out the bitterness of vermouth and other strong flavors.

3. Why do some people prefer shaken martinis over stirred?

The debate between shaken and stirred martinis is a matter of personal preference. Shaking a martini can create a lighter and frothier texture, while stirring can create a smoother and more concentrated drink. Some people believe that shaking can also "bruise" the alcohol, altering its flavor, but this is a controversial topic among scientists.

4. Are there any chemical reactions happening in a martini?

Yes, there are several chemical reactions that occur when making a martini. The most significant one is the dilution of the alcohol when it comes into contact with ice during shaking or stirring. This process, known as "hydration," can change the taste and texture of the drink. Additionally, the botanicals in vermouth can interact with the alcohol and other ingredients, resulting in a more complex flavor profile.

5. How does the temperature of a martini affect its chemistry?

The temperature of a martini can impact its chemistry in several ways. When a martini is chilled, the molecules in the drink move slower, which can enhance the flavors and aromas. Additionally, the colder temperature can also reduce the volatility of the alcohol, making it less pungent. However, if a martini is too cold, it can numb the taste buds and make it more challenging to taste the flavors properly.
