It is not beer any more than ginger beer is beer. They use the term beer in this case to let people know It is not your typical kombucha. It is a high alcohol kombucha. But I understand why its is not allowed
If you read the kombucha do's and dont's though it technically is ok. As long as the alcohol is a byproduct and no sugar is added it is ok. The unity kombucha is made just like other kombucha only using organic tea and fruit juices.
