(1) the reason why coffee beans with fresh and certain quality do not mention fresh coffee beans is to correct a misunderstanding for brown friends that fresh roasting is not directly related to quality. Freshness is a factor and a premise, but freshness is not good. For example, fresh garbage and fresh poop have nothing to do with quality. So if it is poor quality raw beans and poor standards

2014-08-25 Coffee knowledge coffee bean roasting coffee raw beansFirst of all, let's talk about the meaning of baking. Definition of roasting: the so-called coffee roasting (coffee roasting) refers to the heating of raw beans, which promotes a series of physical and chemical reactions inside and outside the coffee beans, and in this process produces a variety of sour, bitter, sweet and other flavors of coffee, forming mellowness and hue, and converting raw beans into dark brown beans. two。 The importance of baking: in the shadow

As long as the drop in the water temperature of the hand pot can be controlled within 4 ℃, many coffee aromatics will show variable vibrations because of their different molecular weight and polarity.

2014-09-29 Coffee knowledge Coffee beans roasting Roasting techniquesThe 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.
2015-03-13 Coffee beans correct grinding methods techniques degree extraction time straighteningIn theory, during the brewing extraction process (the roasting degree of coffee beans is 5565 according to the SCAA standard), the hot water temperature in contact with coffee powder should be kept at 9194 degrees, which is called the best extraction water temperature. Of course, this temperature range is a theoretical value, and experienced producers don't have to be too dogmatic. In practical applications, it may be for a specific brewing appliance, or for a certain type of deep baking.
2016-07-16 Coffee brewing proportion instant coffee powderCoffee roasting refers to the heating of raw beans to convert starch in raw beans into sugar and acidic substances at high temperature. Cellulose and other substances will be carbonized to varying degrees. Moisture and carbon dioxide will volatilize. Protein will be converted into enzymes and fats. The remaining substances will combine together to form an oil film layer on the surface of coffee beans. In the process, coffee acids will be generated.

In addition, they use more household hot air equipment and I-ROAST and NESCO, the price is not much different, between 975-1200 yuan. But the repair rate of NESCO is high, and the baking of I-ROAST is relatively foolish. Relatively speaking, FRESHROAST can support continuous baking (although it can be continuous).
2015-07-06 Huky500 coffee roaster unpacking assemblyThe freshness of coffee beans is one of the factors affecting the grinding degree. Freshly roasted coffee beans because of the high activity of flavor components, do not need too fine grinding degree to emit enough flavor, so the grinding degree can be adjusted properly. At this time, if the degree of grinding is still fine, the flavor components of coffee beans can be more divergent, but it is also easier to extract miscellaneous flavors at this time.

2015-10-13 Coffee beans roasting stages processes needs attention problemsCoffee roasting is the coking of raw coffee beans at high temperature. Roasting completely changes the substances inside the raw beans to produce new compounds, which are recombined to form aroma and mellow flavor. And this effect will only happen at high temperature, if you only use low temperature, it will not cause decomposition, no matter how long the coffee beans are not cooked. Most people think that baking is nothing, just using firefighters.
