Importance of Grinding Coffee Beans
The freshness of Freshly Ground Coffee is paramount for an exceptional coffee experience. Grinding coffee beans increases their surface area by up to 10,000 times, exposing the beans to Oxidation and leading to a rapid loss of essential oils and aromas within just 15 minutes of grinding. This rapid Oxidation causes the flavor to deteriorate significantly, with the taste of ground coffee declining noticeably after as little as three days.
In addition to Oxidation, Moisture and CO2 Depletion also play a critical role in coffee freshness. Moisture in the air can degrade ground coffee, leading to dilution and potential mold growth. Furthermore, the CO2 that develops during roasting helps protect delicate flavor compounds, but this gas is quickly released when the beans are ground, leaving the coffee vulnerable to further Aroma Loss.
