Qianjie-Hand brewed coffee extraction ratio Introduction

In a cup of hand-brewed coffee, up to 98.5% is water. To make a good cup of hand-brewed coffee, the first step is to manage the water quality! At last month's World Coffee Brewing Competition, one of Du Jianing's secrets to winning the world championship was to manage the water quality well. She added appropriate calcium and magnesium ions to the water to increase the extraction ability of the water and bring out more coffee flavor.

The ratio of powder to water is a very critical factor in hand-brewed coffee. Different ratio of powder to water (the ratio of powder and water injection) will greatly affect the flavor performance of coffee. We all know that in the process of hand-brewed coffee, aromatic substances and acids are extracted first, followed by sweet and caramelized substances. Finally, bitter and astringent tastes come out, so we can control the ratio of powder to water.

In general, the quality of coffee beans is excellent (such as half a pound of micro-batch beans with a market price of more than 200 yuan), which is suitable for high powder-water ratio (1:16-1:18); general fine beans (half a pound of market price is about 100 yuan), it is recommended to use 1:13-1:15 powder-water ratio; ordinary commercial beans, want to be washed can be imported, not bitter, it is recommended to use 1:10-1:12 powder-water ratio to wash. For beans with poor freshness (such as baking has been over three months), the good flavor of coffee has run almost, try to use the ratio of 1:8-1:10 to flush, the original beans high quality words, sweet feeling or will remain.

Water temperature will affect the extraction efficiency of coffee, high water temperature extraction fast, low water temperature extraction slow, such as ice drop coffee has to take three to five hours to complete; light roast, high quality beans, with 90-95 degrees to show acid and sweet feeling; medium roast fine beans, with 85-90 degrees water temperature to flush, can show the good flavor of fine beans; General quality beans, medium-depth baked beans, it is recommended to use 80-85 degrees water temperature to brew, as long as it can be clean and odor-free, moderate mellow on the pass.

In a word, don't set yourself limits and brew coffee at only one temperature, but rather according to bean quality/roasting and the flavor you want to express.

Knowledge point: The applicability of hand-brewed coffee is very strong. Deep-baked Italian blended beans can also be hand-brewed, but if you really want to drink the charm of hand-brewed coffee, it is recommended to choose high-quality beans with a cup test score of more than 80 points.
