Web1. Yet, these approaches have several disadvantages. To begin with, the brewer will check the wort gravity, which is the measure of solids dissolved in the wort. As the yeast breaks down the sugar, it emits CO2 and when it can no longer dissolve in the beer, the excess CO2 is released into the air, causing the beer to bubble.
