Coffee enthusiasts and industry experts have discovered that freezing coffee beans can significantly extend their shelf life and preserve their flavor, but there are some critical steps to ensure success. The key is to freeze the beans about 10 days after roasting, once they have released most of their CO2 and the balance between CO2 and oxygen is optimal for maintaining the coffee's aroma. To avoid freezer burn and maintain freshness, beans must be vacuum-sealed or have as much air removed from the bag as possible before freezing. This method has been endorsed by numerous coffee professionals, including World Barista Champions and coffee consultants. Companies like La Cabra and Black & White Roasters are even introducing freezer menus featuring coffees that have been stored under optimal freezing conditions. Whether you’re a home brewer or a professional, following these steps can help you enjoy fresh-tasting coffee long after the beans have been roasted.
