Fermenting in a fermentor has three main benefits. First, it produces less oxygen than fermenting in a corny keg or bucket so your beer will be more pure and vibrant. Second, you can add additional flavors to the beer because it’s easier to get to all parts of the batch when it’s fermenting in a large vessel. Third, you can find many different types of tanks that are tailored for brewing beer, which makes them very useful for home brewing. The fermentation process is important for every type of beer because it helps remove any unpleasant flavors or aromas from the drink. Fermentation also removes any remaining sugars from the mixture so that they don’t change the flavor and create alcohol content.
