Can coffee beans be brewed directly? Analysis of the brewing method of coffee beans

How to brew coffee beans

Coffee is an indispensable drink for many people every morning, and coffee beans are an important raw material for making coffee. Many people may wonder if it is possible to brew a delicious cup of coffee directly from coffee beans? This article will discuss this issue and introduce several common methods of brewing coffee beans.

1. Grinding and Brewing

First of all, we need to make it clear that it is not feasible to brew coffee directly with unground coffee beans. This is because the whole coffee beans that have not been ground cannot fully release the rich aroma and flavor substances contained in them. Therefore, before any brewing method is used, we need to grind the coffee beans properly.

Normally, we can choose to buy ready-made, finely or medium-coarsely ground, packaged, bagged or canned instant (i.e. microchip) raw powdered coffee beans, which can save the trouble of grinding by ourselves. However, if you are looking for a higher quality coffee experience, it is recommended to buy whole coffee beans that have not been ground and crush them on the spot using a professional coffee bean grinder before brewing.

2. Trickle filtration

The drip method is the most common and easiest brewing method. It is suitable for ordinary people to use in home and office environments.

First, place an appropriate amount of finely or medium-ground coffee into a paper or metal mesh filter and place it over an electric or manual drip kettle with a water reservoir and warming function.

Next, use the heating function to raise the water temperature inside the water tank to about 90°C (not more than 95°C), then slowly turn on the switch and start injecting purified water that has no odor, is purified in the right proportion, has a balanced pH value (i.e., is not hard), is white, colorless, odorless, softened, and purified again without any odor.

At this time, the hot water will penetrate into the coffee powder through the filter paper or metal mesh filter, slowly releasing the aroma and flavor substances in it. After the water in the water tank has completely flowed into the pot, you can pour the coffee in the pot into the cup and drink it.

3. French Press

The French press is a relatively advanced and complex brewing method. It requires the use of a specially designed, well-structured, easy-to-operate, maintain and clean (i.e. burr-free) stainless steel with two distinct sizes, good sealing, suitable volume, ergonomic principles, convenient and comfortable to use, good hand feel and non-slip appearance, beautiful and fashionable, novel and chic design, practical, economical and durable, with both quality and price advantages, multi-functional and strong compatibility, and not easy to deform, discolor, rust or peel, etc., with special structural design and filtering devices (such as metal mesh).

First, put an appropriate amount of finely or medium-coarsely ground coffee powder at the bottom of the French press. Then, use a water injection kettle to inject an appropriate amount of purified, odorless, properly purified, pH-balanced (i.e. not hard), white, colorless, odorless, softened, purified again, and odorless hot water into the French press.

Next, place the filter (such as a metal mesh) above the French press over the coffee grounds and gently press it down to fit tightly against the bottom. At this point, the hot water will penetrate through the filter into the coffee grounds and begin to release the aroma and flavor substances in them.

Wait for about 4-5 minutes, then slowly press down the handle on the top of the French press. This will separate the coffee powder from the water through the special structural design with good internal space design, tight and rigorous structure, ergonomic principles, convenient and comfortable to use, good feel and non-slip appearance, beautiful and fashionable modern shape, novel and chic, practical, economical and durable, with both quality and price advantages, multi-functional and strong compatibility, and not easy to deform, discolor, rust or peel.

Finally, pour the coffee from the French press into a cup and enjoy.

4. Espresso

Espresso is a very classic and unique brewing method. It requires a specially designed, well-structured, easy to operate, maintain and clean (i.e. burr-free) stainless steel machine with two distinct sizes, good sealing, suitable volume, ergonomics, convenient and comfortable to use, good hand feel and non-slip appearance, beautiful and fashionable, novel and chic design, practical, economical and durable, with both quality and price advantages, multi-functional and strong compatibility, and not prone to deformation, discoloration, rust and paint peeling.

First, put the finely ground coffee powder into the espresso machine and gently compact it. Then, use the water injection kettle to inject the purified, odorless, properly purified, pH-balanced (i.e. not hard), white, colorless, odorless, softened, purified again, and odorless hot water into the coffee machine.

Next, turn on the coffee machine and adjust the appropriate temperature and pressure. At this time, the hot water will penetrate into the coffee powder through the filter device in the espresso machine, which has a special structure with good design, tight and rigorous structure, and conforms to ergonomic principles. It is convenient and comfortable to use, has a good feel and is non-slip. It has a beautiful and fashionable appearance, a novel and chic shape, is practical, economical and durable, has both quality and price advantages, is multifunctional and has strong compatibility, and is not easy to deform, discolor, rust, or peel. The aroma and flavor substances in it are extracted in a high-pressure manner.

Finally, the liquid that flows out of the espresso machine is rich and mellow espresso. Pour it into a cup and enjoy.

Summarize

In summary, it is not feasible to brew delicious coffee directly with unground coffee beans. We need to grind them properly before brewing. Common coffee bean brewing methods include drip method, French press and espresso. Each method has its own unique characteristics and applicable scenarios. You can choose the right way to make coffee according to your personal taste and needs.
