Because there were relatively few siphon pots in the store before, there was not much research on brewing parameters. In fact, it was nothing more than water temperature, grinding degree, powder-water ratio and brewing time. Recently, someone suddenly asked how to determine the grinding degree in the face of coffee beans that had not been cooked in siphon pots. The simplest idea, of course, is to adjust the grinding of hand-brewed coffee as a reference value, but the question comes again: siphon pot coffee beans compared to hand-brewed coffee, grinding should be coarse or fine?

Source of contradiction:

Because hand-brewed coffee is a cooling extraction, siphon pot coffee is a warming extraction, so even if the starting temperature is the same, the average extraction temperature of siphon pot coffee will be 2- 3 degrees higher than hand-brewed coffee. To prevent over-extraction, siphon pot coffee should be ground coarser?

Because the extraction time of hand-brewed coffee is usually about 2 minutes, while the extraction time of siphon coffee is about one minute. Moreover, hand-brewed coffee is filtered extraction, siphon pot coffee is steeped extraction, in terms of extraction rate, hand-brewed coffee should be higher than siphon pot. Siphon pot coffee should be ground more finely to prevent over-extraction

Finally decided to do an experiment to see what kind of grinding is more suitable for siphon pot coffee?

Since our daily hand-brewed coffee is recommended to grind BG: 4M, these two parameters are selected to compare, just slightly thicker than the hand-brewed coffee grind by 1 scale and slightly finer by 1 scale.

For other parameters, try to use the same method to ensure the objectivity of the comparison. For example, the ratio of powder to water, water temperature, brewing time and stirring method.

Specific brewing records:

20.8 g beans, 240 g water, 90°C water temperature, powder added later. Add the powder and stir for 5 cycles, steam for 39 seconds, stir for 5 cycles, turn off the fire for 60 seconds, stir for 2 cycles, and then cool quickly to reduce pressure and accelerate siphon reflux.

Flavor Description Comparison:

Experimental group ①: nuts, lemon fruit acid, citrus, peach honey, dark chocolate, bitter taste obvious, oil feeling obvious, taste slightly bitter; after a little cool sour become obvious, aroma is more obvious, the whole is more dense but still slightly bitter.

Experimental group ②: fruit acid, grapefruit, citrus, aroma is obvious, oil feeling is light, taste is light, bitter taste is less, taste sour, overall light, but the flavor sweet feeling is balanced.

Voting results: experimental group 2 slightly better.

Brewing analysis: Excluding the influence of technique and parameter matching, indeed, in the case of fine grinding, the flavor of the siphon pot will be more complete, the mellow degree will be better, the front, middle and rear flavors will be colorful, but there will be a suppressed feeling, and the bitterness will be easier to come out. After all, there will be three times of stirring and not low water temperature brewing; In the case of rough grinding, the flavor will have some defects, the overall is relatively thin and light, the taste is somewhat close to the hand-brewed coffee, but the overall layered feeling is expressed, the taste is relatively easy to accept, the key is the high fault tolerance rate, and will not easily "dog belt"! For unfamiliar siphon pot operation, or do not understand the characteristics of beans, especially suitable.

Comparative conclusion: Although it is only a comparison of two groups of siphon pot coffee, but through simple comparison, we can still draw: in the overall brewing idea is not clear, there is no relevant brewing experience and data for reference, slightly coarse grinding will be more suitable for everyone_because of high fault tolerance rate, even if busy, at least not because of brewing time is too long, and brewing a cup of strong and bitter, burnt strong siphon pot coffee, and this, is not the beginner playing siphon pot most likely to hit the "wall"?
