Lesson details

How you store your coffee beans can drastically affect the taste of your coffee. Most coffee beans come in a bag with a one-way valve, it may look useless, but this bag plays a pretty big role in making sure your coffee beans stay fresh.

After being roasted, coffee beans store CO2 gas which is released over time. The valve on the coffee bag allows the CO2 gas to escape slowly without letting oxygen, which can make coffee taste dry and oily, in.

In this lesson, learn about the ways of storing coffee beans and why storing coffee beans correctly is important.

This course is perfect for budding baristas or someone wanting to improve their skills and knowledge behind an espresso machine.
