Discovering the Science Behind Fizzy Angostura Bitters & Tonic Water

In summary, the addition of Angostura Bitters to tonic water causes a faster and more vigorous fizzing reaction due to the spices and other insoluble ingredients acting as nucleation sites for CO2 bubble formation. This is similar to the effect of adding salt to boiling water, where the salt dissolves and creates a concentrated area of fizzing. This phenomenon is reminiscent of the famous coca cola light and menthos experiment.

If I add Angostura Bitters to a glass and then add tonic water it fizzes up far faster than tonic alone, at some stages it produces a foam with large (1/4 to 1/2 inch dia), can anyone explain what's happening?

Just a guess because Wikipedia says that angostura bitters are made from a secret recipe. The insoluble spices and such inside provide a sites of nucleation for CO2 bubble formation which causes the fizzing. You can see this effect when putting salt into boiling water, like before throwing in some pasta to cook. Salt is soluble but the first moment after dropping in the salt you will notice fizzing and bubbling being concentrated in the area where the salt went, this effect quickly terminates due to the salt dissolving in the water.

Again, just a guess.

Makes me think about coca cola light and menthos.
 

1. What is the science behind the fizz in Angostura bitters and tonic water?

The fizz in Angostura bitters and tonic water is due to the presence of carbon dioxide gas. This gas is added during the production process and is what creates the bubbles and fizziness in the drinks.

2. How does Angostura bitters and tonic water work together?

Angostura bitters and tonic water work together to create a refreshing and flavorful drink. The bitterness of the bitters is balanced by the sweetness of the tonic water, while the carbonation adds a bubbly texture to the drink.

3. What are the health benefits of Angostura bitters and tonic water?

Angostura bitters and tonic water have been used for medicinal purposes for centuries. Bitters are believed to aid in digestion, while tonic water contains quinine, which is known for its anti-malarial properties. However, it is important to consume these drinks in moderation as they do contain alcohol and sugar.

4. What is the history behind Angostura bitters and tonic water?

Angostura bitters were first created in 1824 by a doctor in Venezuela as a digestive aid. Tonic water was originally used as a way to prevent malaria due to the quinine content. Today, both drinks are popular as mixers in cocktails and non-alcoholic mocktails.

5. How can I incorporate Angostura bitters and tonic water into my recipes?

Angostura bitters and tonic water can be used in a variety of recipes, from classic cocktails like gin and tonic to non-alcoholic options like mocktails and spritzers. You can also use bitters in cooking and baking to add a unique flavor to your dishes.
