Boutique coffee the ingredients of boutique coffee beans
Sugar: without sugar, you will not only feel the bitterness of caffeine and the sour taste of tannin, but also feel sweet, which is caused by the sugar contained in the coffee itself. After baking, most of the sugar will be converted to caramel, bringing a unique brown to the coffee.
Minerals: there are lime, iron, sulfur, sodium carbonate, phosphorus, chlorine, silicon and so on, because the proportion of very little affect the flavor of coffee is not big, combined to bring only a little astringent taste.
Crude fiber: raw bean fiber will be carbonized after baking, this carbon and sugar caramelization combine with each other to form the tone of coffee, but the fiber turned into powder will have a considerable impact on the flavor of coffee. Therefore, we do not encourage the purchase of powdered coffee beans, because we are unable to taste the flavor of the coffee.
The bitterness of coffee: the color, aroma, and taste of coffee are caused by complex chemical changes that take place during roasting. Therefore, raw beans must go through appropriate chemical procedures to achieve the most balanced state of its essential ingredients in order to be regarded as the best baked beans. The aroma of coffee changes with the heat, so the baking time should be shortened as much as possible, and the heat should be controlled at the lowest temperature that can produce effective chemical composition of coffee beans, that is, the time and heat of the shortest process, so that coffee beans can produce the most suitable composition ratio.
Aroma: aroma is the life of coffee quality, and it can best represent the coffee production process and baking technology, as well as the climate, elevation, variety, refined treatment, harvest, storage, roasting technology of the consuming country, etc. are the conditions that determine the aroma of coffee beans. The results of gas chromatographic analysis showed that the aroma of coffee was composed of acid, alcohol, acetaldehyde, ketone, ester, sulfur compound, phenol, nitrogen compound and nearly hundreds of volatile components. Generally speaking, fat, albumen and sugars are important sources of aroma, while lipids blend with the sour and bitter of coffee to form a smooth flavor. Therefore, the disappearance of fragrance means that the quality is getting worse, and the relationship between aroma and quality is very close.
