V60 is also a kind of filter cup with many ways to play.

Can be deep pit, can be flat, can be round ball, can be slightly concave. Wait, wait.

What they said is correct, it just represents different schools, and hand-washing the surface of the pit can actually see a lot of problems, not completely impossible to judge.

And friends, you give the picture, the extraction seems to be uniform, but there are two bad possibilities.

1. Lack of flavor

The hand turns around without sinking, which means that your brewing does not choose too much water under the edge, but the current is relatively small, plus the powder is not fine (it may be bad to grind, thick on top).

It is judged that the whole process of the small flow may lead to the lack of flavor of the extraction.

two。 Bitter

The upper particles are too large and the fine powder precipitates, resulting in bitterness.

Rough judgment, welcome to discuss.

It is suggested that the back part of the water flow should be enlarged on the premise of keeping the water injection evenly.

If there is too much fine powder, change the mill.

Each school will have different potholes. It is good to study a school individually or to understand each school extensively.

Basic skills are all necessary.

The question is how to reach it, the small current does not rush the edge and turns evenly. The flow does not break the powder wall, three-stage water injection or two-stage water injection. Keep the surrounding pink wall intact and float with the page.

After a careful look at the powder, the flow in the latter section should have been enlarged, and the powder layer floated high enough.
