What is oxygen? What is the role of oxygen?Oxygen is a chemical element and an active gas essential for life on Earth. It also plays an important role in the beer fermentation process.Oxygen is often regarded as the gas that sustains life, but it serves a different function in the beer fermentation

How does temperature affect beer?High temperature fermentation can cause off-flavors in beer, such as fruity esters and solvent-based higher alcohols. Acetaldehyde (green apple), in particular, is produced more rapidly at high temperatures and is one of the most common defects in homebrew. Fermentat

Fermentation is the process by which yeast converts the glucose in the wort into ethanol and carbon dioxide gas. To start the fermentation process, the cooled wort is transferred to a fermentation tank where yeast has been added. Without fermentation, there is no alcohol, the sugars are not degraded
