Beer is a perishable food product. There are many ways that beer can become contaminated before it arrives at your business, or it can just get too old. It is important to be able to identify “off” flavors so you know when to get the customer a replacement.
Taste and flavor
By becoming more aware of your senses and then developing a vocabulary to articulate those senses, you can develop a deeper understanding of beer. When you are better able to tease out different aromas and flavors, and when you are able to articulate those senses into words, you can better understand why different characteristics are present in a beer, you can understand what a customer wants, and you can know when a beer has gone bad.
