For centuries, beer has been a favourite drink throughout the world. The art of brewing has more recently evolved into the science it is today as a result of the increased knowledge of both the ingredients and the process.Considerations such as appearance, taste and the nutritional value of beer are important topics for consumers and brewing scientists alike.
