Guidelines for brewing golden cups of coffee
What is the best? what is the appropriate ratio of sour to bitter taste? all these need to be adjusted according to individual tastes. If you cook them for others, you should choose beans according to the preferences of coffee drinkers, change the hot water temperature, extract time and grinding degree, and find the best value. The taste of coffee roasted from light to medium is sour and sweet with low molecular weight and medium molecular weight.

According to the research of Dr. Lockhart and Ringo, a senior consultant of SCAA (American Fine Coffee Association), as far as coffee extraction is concerned, the dissolution rates of flavor molecules and hot water often vary according to molecular weight and polarity. Coincidentally, the low molecular weight sour aroma of flowers and fruits, as well as the taste of nuts and toast, as well as the cereal and rice and wheat flavors produced in the early stage of the Mena reaction will be excellent.

Learning essentials of SCAA Coffee Flavor Wheel the origin of coffee flavor wheel
Coffee has only four kinds of water-soluble tastes: sour, sweet, bitter and salty, some sour and sweet, only volatile, which need to be identified by smell; some are non-volatile, only water-soluble, and need to be identified by taste buds; and some sweet and sour ingredients are both volatile and water-soluble, so sour and sweet often show the dual senses of smell and taste. As for bitterness and saltiness, there is no volatility.

Introduction to the difference between the standard dosage of coffee powder in siphon pot
Roughness is a good way to control bitterness, because the finer the grinding, the higher the extraction rate, the easier it is to extract high molecular weight bitter substances such as chlorogenic acid, quinic acid, caffeine and carbides. On the contrary, if the grinding is too rough, the lower the extraction rate is, the more difficult it is to extract the astringent bitter substance with high molecular weight, but the sweet taste with middle molecular weight may remain in the coffee grounds because of insufficient extraction, which is a waste.

Detailed analysis of low molecular weight sugars in coffee beans
Moisture: the water content of coffee beans varies greatly with different processing stages and products. The moisture content of wet coffee beans with film is about 50%, while that of dried raw coffee beans is about 10%-13%. The water content of roasted coffee beans is only less than 5%. The existence of water in coffee beans is the same as other kinds of food and beverages, because it contains a considerable amount of hydration colloid macromolecules.

Do not drink unbaked coffee roasting degree
The heat of shallow roasting is mild, because the sour aroma of flowers and fruits is most preserved by fermentation, so it is easy to smell the sour aroma of coffee. If the baking continues, that is, from the end of the first explosion to the middle baking before the second explosion, or even the medium and deep baking from the first explosion to the second explosion, most of the sour aroma of the fermentation catalysis has been broken up, instead of the taste spectrum of the sugar browning reaction (Sugar Browning) and Mena reaction.

Coffee roasting degree coffee roaster coffee beans death wish coffee
The term "fine coffee" was first put forward by Ms. Knudsen of the United States in Coffee and Tea magazine. At that time, Ms. Knudsen, as a coffee buyer at B.C. Ireland in San Francisco, was very dissatisfied with the neglect of the quality of raw coffee in the industry, and even some big roasters mixed a large amount of Robesda beans in the comprehensive beans, so she put forward the concept of boutique coffee.

The baking degree determines the taste spectrum towards deep roasting, shallow roasting, moderately roasted coffee beans.
Coffee taste spectrum consists of "smell spectrum" and "taste spectrum"; the former directs dry and wet fragrance, while the latter refers to water-soluble taste. The aroma of "odor spectrum" is appreciated by the sense of smell before and after the nose, and the liquefaction taste of "taste spectrum" is captured by the sense of taste. The "smell" and "taste" of coffee often vary with variety, altitude, soil and water, producing area, post-preparation, extraction and roasting degree, but

Coffee Flavor Wheel and flavor spectrum
The coffee taste spectrum was drawn by Tedelingo, a senior consultant of SCAA in 1997, and is composed of normal taste spectrum and abnormal taste spectrum. The so-called normal taste spectrum refers to the normal taste spectrum of coffee, while the abnormal taste spectrum refers to the abnormal taste spectrum of raw beans under abnormal conditions, such as improper processing, transportation and storage, resulting in deterioration of coffee protein, organic acids and fats, or improper roasting.

The purpose of "Coffee Flavor Wheel" is to establish the same term of coffee taste spectrum, to assist cup testers or professionals to further understand the connotation of coffee aroma and taste, and to describe the sensory understanding of coffee in the future, so as to have a common language. In order to facilitate the analysis, the Coffee Flavor Wheel is disassembled into two fan-shaped diagrams. This issue will first introduce the "odor spectrum". Coffee taste spectrum consists of "odor spectrum" and "nourishment".

The correct Grinding method of Coffee Bean
The degree of grinding should be proportional to the extraction time. The roughness of coffee grinding will directly affect the extraction time and extraction rate. The finer the coffee is ground, the denser the powder layer is, the more coffee powder particles are in contact with hot water, the greater the extraction resistance, the easier it is to prolong the extraction time and improve the extraction rate, and it is easy to over-extract. On the contrary, the thicker the coffee is ground, the larger the gap in the powder layer is, and there are fewer.
