Can coffee beans be brewed directly after being ground?

Coffee is a must-have drink for many people every morning, and for real coffee lovers, they pay more attention to the quality and taste of coffee. When making a delicious cup of coffee, it is very important to choose the right grinding degree. So, can we brew directly with ground coffee beans? The following will explore from several aspects.

1. Storage period

Once coffee beans are ground into powder form, they immediately release their aroma and oils. These aromas and oils are easily decomposed or oxidized by factors such as air, light and humidity. Therefore, it is best to use freshly ground coffee as soon as possible before brewing.

2. Oxidation process

When we store whole, untreated coffee beans in jars, they are relatively rarely exposed to air. However, once the beans are ground into a powder, their surface area increases dramatically, exposing more of the coffee to air. This causes the oils and aromas in the beans to oxidize quickly, and can create a bitter taste when brewing.

3. Grinding degree

Different brewing methods require different degrees of grinding. For example, finer powder is needed for espresso, while coarser powder is needed for filter coffee. If we directly brew with coffee beans that have been ground but are not suitable for the fineness required by the current brewing method, we may not achieve the ideal taste.

4. Taste quality

Fresh beans are better at maintaining integrity and freshness than beans that have been broken and exposed to the air for a period of time. Therefore, when pursuing the best taste and flavor quality, it is recommended to use freshly broken beans on site or a manual crusher to break them on site.

5. Cold Brew vs. Instant Coffee

Cold brew coffee and instant coffee are two special brewing methods. For both methods, we can use ground coffee directly. Because these methods do not require water to flow through the powder during the production process, there will be no excessive oxidation and bitterness.

in conclusion

In summary, although we can brew coffee directly with ground coffee beans, it is best to use freshly ground or manual grinders to grind them on site as soon as possible. This ensures better retention of aroma and oils, and a cup with better taste and flavor quality.
