Should you brew coffee beans immediately after buying them? Why can filter coffee beans be used after resting for three to five days, while espresso beans need to wait a few more days? Behind this are multiple factors involving carbon dioxide release, roast level, and extraction method. This article starts with the basic principles of the resting period, then explains one by one the two main reasons espresso coffee beans need a longer resting time: first, espresso beans are generally roasted darker, so they accumulate more carbon dioxide inside; second, espresso uses pressure extraction, with an extremely fine grind and very short time, so insufficient degassing will noticeably amplify its interference with the extraction result.
