How It Works

Priming sugar provides food for residual yeast to produce CO2 in the sealed bottle. The amount depends on beer temperature (cold beer holds more dissolved CO2, so less priming sugar is needed), target carbonation level, and sugar type. Standard CO2 volumes: British ales 1.5-2.0, American ales 2.2-2.7, Belgian ales 2.5-4.0, German lagers 2.4-2.8, wheat beers 3.0-4.5. Corn sugar (dextrose) is the standard choice. Table sugar works equally well but ferments slightly more efficiently. DME adds a small amount of body and flavor but requires about 20% more by weight.
