What is the difference between freshly ground coffee and pre-ground coffee? How is hanging ear coffee made? How to make it taste good?

Recently, the topic of freshly ground coffee is very hot, so a friend came to the store and asked an interesting question: what is the difference between freshly ground coffee, hand-ground coffee and pre-ground coffee powder?

It's hard to explain in a few words, so. Qianjie is going to have a good chat today. What's the difference between these coffee powders with different prefixes?

What is freshly ground coffee powder? The so-called freshly ground coffee powder is to grind out the coffee powder to be used on the spot when preparing for brewing. This kind of behavior of making coffee powder on the spot is called "fresh grinding". The coffee brewed with these freshly ground powders is freshly ground coffee. No matter what ingredients, we all pay attention to one word: "fresh". Because fresh ingredients can have the most abundant aroma and taste, the same is true for coffee. Before cooking, beans only need to maintain an airtight structure to slow down the loss of gas.

If they are still in a vacuum, then they will be able to maintain the existence of flavor substances for a long time. This is particularly important for consumers who are mainly hand-made, because they have more stringent requirements for the flavor of coffee, but because of less consumption, they can't drink all the beans quickly. so you need to store the beans in full shape and grind them when you want to drink them, so you can keep the beans with excellent flavor for a long time.

What is hand-ground coffee? Hand-ground coffee powder refers to the use of hand-ground coffee powder, the grinding equipment can be either a hand grinder or a hand-pounded stone mortar, as long as it is driven by manpower.

But the reason why the hand mill as a separate category, because in the grinding of coffee beans, there is also the use of electricity-driven grinding, and this kind of electricity for grinding is called electric grinding.

Because of the relationship between the cutter head and the power source, the uniformity of the coffee powder will be very different, so the two have always been the object of comparison. But you know, because of the different ways of use, each has its own advantages, and there is no difference between good and bad ~ if you want to be easy to carry, do not use electricity, then choose a hand grinder; if you want to grind evenly, save time and effort, choose an electric bean grinder.

What is pre-ground coffee powder?

Pre-ground coffee is the opposite of freshly ground coffee powder, which is ground long before brewing. There are many reasons for pre-grinding, either for convenience and convenience, for pre-grinding before travel, or for coffee powder to discharge too much carbon dioxide, so that hot water has better extraction space, and so on. The most representative is hanging-ear coffee, which is used by merchants to reduce the steps of operation for buyers by grinding and bagging in advance. But the only drawback is that when the interval between grinding time and brewing time is too long, the flavor of coffee will not be as full as it is now ground.

Because when the coffee beans are roasted, they will continue to discharge carbon dioxide and flavor substances from the body. The more air you are exposed to, the faster the loss will be. So we need to find a sealed container to store coffee beans, so that we can reduce the contact between fresh air and coffee beans, so the flavor can be preserved for a long time. However, when coffee beans are ground into powder, they will be exposed to more air because of the increase in surface area. As a result, the best taste period, which could have lasted for more than a month, has been shortened, leaving only about half of the original. Because the loss of flavor substances is accelerated, so the appreciation period becomes shorter.

Therefore, if you want to feel the rich and varied flavor in the coffee, the coffee powder had better be freshly ground. After all, the flavor of coffee powder has been greatly lost within two hours of grinding. How to choose depends on the individual choice!
