Qianjie-Hand brewed coffee thickness, single bean variety introduction

Grinding thickness is one of the factors affecting hand punching.

Grindability refers to the size of coffee particles, which simply means that the size of coffee particles affects the contact time between coffee and water.

Grinding thickness → contact surface number, dissolution rate Fine grinding, so that hot water can extract more substances at the same time, there is also the possibility that if the grinding is too fine, too much substance may be extracted, easy to over-extract. If coarse grinding is selected, hot water can extract less substances at the same time. On the contrary, grinding too coarse may extract too little substances and easily extract insufficient substances.

Bean grinder is mainly divided into blade grinder and gear grinder, hand-brewed coffee grinder selection gear grinder, when grinding coffee beans, because the blade is often uneven cutting, will produce very fine powder, but gear grinder, can ensure the stability of coffee grinding degree, uniform, therefore, gear grinder is better than blade grinder.

The finer the grinding degree, the stronger the bitterness, and the coarser the grinding degree, the lighter the bitterness. If the particle size is different, the extraction degree of each particle will be different, and the taste of coffee will also be affected. Therefore, the grinding degree of coffee can be the size of granulated sugar particles. This is the grinding degree with a wide range of application.

Coffee grind fineness can control bitter taste, but different coffee brewing methods need to choose different grind. Generally, the suitable extraction method for the coarse grinding degree is cold extraction, the suitable extraction method for the coarse grinding degree is pressure, the suitable extraction method for the coarse grinding degree is drip filtration, the suitable extraction method for the medium grinding degree is hand flushing or conical filter bowl drip filtration, the suitable extraction method for the fine grinding degree is Italian concentration, and the suitable extraction method for the fine grinding degree is Turkish coffee.

It is recommended that novices use medium powder to carry out hand flushing first. After all, grinding medium powder is not easy to produce extremely fine powder, and it is not easy to soak coffee powder on the filter cup due to unstable control of water flow at the beginning, thus making coffee extraction excessive. In addition, because personal tastes are different, you can try more between medium powder and fine powder to find the thickness that suits you. The grinding degree of hand-brewed coffee is medium fine, and the grinding is based on the thickness of fine sugar.

There are many varieties of hand-brewed coffee, according to their own flavor area to choose, simply choose Arabica coffee beans basically can not be wrong. Such as blue mountain, kona, rose summer, yejia sherry, etc. are arabica varieties.
