When the temperature and grinding degree are the same, but do you still think that the coffee brewed is not ideal? It may have something to do with the proportion of powder you choose.

| how important is the ratio of powder to water to a cup of coffee?

In the production of hand-brewed coffee, the amount of water has a great impact on the flavor of coffee, different powder-to-water ratio will affect the flavor, taste and so on. The water supply is less, too rich, and the flavor is not clear enough; the water supply is too light and even tastes like a cup of coffee-flavored water.

As we all know, the ideal extraction rate of gold cup extraction is in the range of 18%, 22%, and the concentration range is in the range of 1.15%, 1.45%. But we usually do not have those things at home that can test the concentration, so how do we know what powder ratio is suitable for a bean?

The shallow, medium and deep baking degree editor chose [Panamanian Flower Butterfly], [Yemeni Moka] and [Jamaica Blue Mountain] to do the experiment, while the powder-water ratio tried the powder-water ratio of 1:13, 1:15 and 1:17 respectively.

[Panamanian Flower Butterfly]: BG grind 5m (Chinese standard No. 20 sieve pass rate 60%), water temperature 90 ℃, powder / water ratio: 1:13, 1:15, 1:17, cooking time (time for steaming starts): 39,55 ", 2: 10", 2: 27 ".

[Yemeni mocha]: BG grind degree 5R (Chinese standard No. 20 sieve pass rate 56%), water temperature 89 ℃, powder / water ratio: 1:13, 1:15, 1:17, cooking time (time for steaming starts): 1mm 39 min 50 ", 2x 05", 2x 14 ".

[Jamaica Blue Mountain]: BG grind degree 6m (Chinese standard No. 20 sieve pass rate 50%), water temperature 85 ℃, powder-to-water ratio: 1:13, 1:15, 1:17, cooking time (starting time for steaming): 39,35 ", 1mm 46", 1x 57 ".

The editor tried these three powder-to-water ratios respectively, and I think the powder-to-water ratio of shallow-baked beans can be elongated appropriately, while medium-baked and deep-baked beans are more suitable for a smaller powder-to-water ratio.

After roasting, the structure of coffee beans will become loose and brittle, and the flavor substances inside will be extracted more easily, so some bad flavors will appear after lengthening the powder-to-water ratio. and most of the deep-baked beans focus on dark chocolate, caramel flavor and mellow taste, if lengthened the powder-to-water ratio, the whole will lose the characteristics of deep-baked beans.

In shallow baking, the baking time is shorter than that of moderate and deep baking, so the damage to the structure of coffee beans is not as severe as moderate and deep baked beans, and the flavor molecules are locked more tightly. In particular, beans at high altitude are hard and will be more resistant to extraction, so even if the powder is longer than later, it is not easy to produce some bad taste.

However, the powder-to-water ratio is not fixed, but varies according to the cooking utensils. For example, when we concentrate, the powder-to-water ratio is mostly 1 / 15 or 1 / 2; ice drop coffee is 1:10, and so on. If you want to get a good cup of coffee, choose the parameters you want based on your understanding of the bean, and then extract a cup of coffee that you are satisfied with.
