Hand brewed coffee steaming and water injection methods Hand brewed coffee water temperature and powder water ratio data

Powder is too fine, water will stay longer, soak too long coffee will taste.

The powder is too coarse, the retention time of water in the coffee powder is too short, and the taste is still left in the powder, which is not extracted.

Procedure and speed of water injection

Before pouring coffee into the filter paper, rinse the filter paper with hot water to remove the taste of pulp on the filter paper, so that the coffee aroma and taste will be purer.

Water injection should be fine, slow and uniform. Slow speed, not too fast. It is usually divided into three stages of water injection.

The first water injection, the hot water evenly and gently injected into the coffee powder above, the coffee powder fully soaked, after a slight pause, let the water be absorbed by the coffee. Some people call it "stewing," some say 25- 30 seconds.

The main focus of the first stage of water injection is to make the coffee powder absorb water evenly, so that the coffee is in a state of saturated water absorption, so that it can have a more complete extraction.

If the water injection is too fast, the coffee powder does not absorb the water sufficiently evenly, the coffee powder will float on the water, there is no effective extraction of coffee, and the coffee flavor will be greatly reduced.

The second injection, also slow, raises the water level about a centimeter above the coffee powder level.

A third injection, slowly injecting the water we want to extract. When the coffee is extracted, you can enjoy it.

Divided into three stages of water injection is a common way, in addition, some people like to use the way without water, but also has a flavor.

The amount of coffee varies, and the amount of water flow should also be adjusted.

Coffee powder less, water retention time is shorter, so the water injection speed should be slow, so that coffee has enough extraction time;

Coffee powder, water retention time is longer, water injection speed can be faster, do not let coffee soak too long.

The amount of powder, water temperature, thickness, water injection speed, different collocation will have different taste, this is also the fun and skill of hand brewed coffee.

Skill is practiced, practice makes perfect; no matter what skill, it is a wonderful thing to be able to enjoy freshly brewed coffee freely.
