Removing Air from Drinks
Removing dissolved gas or trapped air can change how much a drink foams, how it looks and how it fills.
How it works
A vacuum pulls dissolved gas and tiny bubbles out of the liquid. This can happen before heating, filling, or other steps, depending on the recipe.
A test with air removal and another without it can show how the step affects foaming, color or dissolved oxygen. The other settings stay the same.
