Roasting deduction of coffee beans

Roasting deduction of coffee beans

The roasting degree of coffee beans determines the style and characteristics of coffee beans, and the roasting degrees of coffee beans in different producing areas are different! According to the taste extracted from the coffee bean producing area and suitable roasting, it can be roughly divided into fruity coffee beans, balanced coffee beans and thick bitter coffee beans. Baking degree shallow and deep [physics]: darker color, fewer folds, less density, larger volume, and stripping.

Coffee beans preserve the basic knowledge of coffee lovers

Coffee beans preserve the basic knowledge of coffee lovers

(1) the three major factors affecting coffee beans: degree / degree / sunlight (2) the best tasting period of coffee: coffee beans are four grams, coffee powder is one gram. (3) the storage life of coffee beans in vacuum packaging is about 24-28 months. Flexible plastic film vacuum bag is a very important subject for 12 months to minimize the physics and chemistry of coffee. By

There are two reasons for the excessive extraction of espresso.

There are two reasons for the excessive extraction of espresso.

All modern coffee extraction is the two core processes of soaking and filtration, which belongs to the category of physics, and there is basically no chemical change in the process. The differences in the thickness of coffee powder, the length of soaking time, the method of separation and filtration, and so on, have created a wealth of coffee brewing utensils and techniques. Although the core process of coffee extraction is the same, according to the pressure used in coffee extraction and the extraction

Train Museum to Cafe? The designer world always surprises you.

Train Museum to Cafe? The designer world always surprises you.

Xie Er, the venomous tongue god in "The Big Bang Theory," loves trains from the bottom of his heart. He has an episode of childish behavior when he goes to the train restaurant. Of course, he is not childish in his normal state. If he knew that three new train restaurants had appeared at the National Railway Museum in Yorkshire, would he have dropped quantum physics and taken off his green hat?

Coffee brewing method: the principle of siphon pot and matters needing attention in operation

Coffee brewing method: the principle of siphon pot and matters needing attention in operation

Principle: when you heat the pot, the temperature of the water in the pot rises. Many people think that the later principle is that the next kettle boils, and the steam suppresses the hot water on the kettle, and the principle is correct, but as a university has also studied physics, the obsessive-compulsive disorder should be explained here: to be exact, the principle is that the lower kettle produces a lot of steam in the process of rising temperature, and the top of the kettle is free.

The Secret of Italian Coffee Machine for making Coffee

The Secret of Italian Coffee Machine for making Coffee

The Italian coffee machine uses pressure to quickly pass the steam through the coffee powder and extract the best ingredients from the coffee, so the time for the steam to stay in the coffee powder directly affects the quality of the brewed coffee. This statement is a bit like a physics textbook. It's not easy to understand.) Scoop the coffee powder into the coffee filter, see that the coffee exceeds the horizontal line of the lid, and cut it with a flat knife or spoon.

The principle of steaming? what is steaming?

About the steaming of coffee. Many baristas or enthusiasts have different opinions on the way, time and amount of steaming, and learn the process of steaming from the physics of steaming in coffee making. When the coffee bean is ground into a coffee powder, the coffee powder we can see with the naked eye is a whole one, but in fact, the microstructure of the coffee powder is similar to that of a honeycomb.

Black coffee with some foam coffee is not easy to spill.

It is not easy for bleary-eyed people to bring a full cup of coffee from the kitchen to the restaurant. With the pace of the person, the liquid surface of the coffee will shake constantly, and a little shaking will overflow from the mouth of the cup. However, the situation of lattes covered with foam is different. These foams not only provide creative space for thermal insulation and coffee flowers, but also have excellent shock absorption.

Coffee extraction principle

Coffee extraction principle Coffee production equipment is various and methods are different, but the core extraction principles are all the same. The core process of coffee extraction principle is: (1) crushing coffee beans to increase the surface area of coffee in contact with water; (2) fully soaking coffee powder in aqueous solution and hydrophilic dissolution of coffee essence; (3) separating coffee solution and coffee grounds. All modern coffee extracts are soaked,

Siphon

Siphon

The plug pot, invented by the British technician Napier, uses the siphon phenomenon in physics to brew coffee, so it is also called a siphon pot or a vacuum pot. The use of the plug pot is very simple: put hot water into the lower pot to heat, after the water boils, put the upper pot containing coffee powder, hot water will enter the upper pot through the pipe and mix with coffee powder to extract the ingredients. Stop when all the hot water has been sucked into the kettle
