Carbonation in beverages is measured in volumes of C02, which refers to the number of liters of gas dissolved in one liter of liquid.

Sodas fall between 3.0 and 4.0 volumes, while energy drinks & tend to have lower levels. 

The "Super Fizz" Category | 4.5 – 6.0+ Volumes

These have the most aggressive bubbles, often requiring special reinforced glass to prevent the bottles from exploding.

High Carbonation: Standard Sodas & Mixers | 3.5 – 4.0 Volumes 

This is the "sweet spot" for most major global soft drinks.

Medium Carbonation: Sparkling Waters & Energy Drinks | 2.5 – 3.2 Volumes

These have a noticeable "zip" but are less sharp than a standard cola. 

Low Carbonation: Fruit Sodas & Ales | 1.5 – 2.2 Volumes

These drinks are often described as "refreshing" or "soft" rather than "fizzy." 

A guide to fine tuning carbonation in your new beverage - in the lab and in pilot production

Lab-made carbonation isn’t exactly the same as carbonation on a mass production line.

One way to get an accurate taste test is to bring ice-cold “reference” drinks that match the carbonation level you like, keep them in a cooler the entire time, and have the lab team keep both the references and new prototypes ice-cold before, during, and after carbonation and tasting. This lets the team compare side-by-side and adjust carbonation to match as closely as possible.
