Coffee utensils _ coffee filter cup _ coffee hand pot _ bean grinder

It is not difficult to find coffee utensils made of various materials on the market.

How does the difference affect the flavor of coffee?

Hand punch pot

There are hand punching pots of various sizes and materials on the market that can be selected according to demand.

It is the size of the spout that will affect the cooking flavor. In general, it is easier to control the amount of water out of the pot, so it is suitable for beginners to use.

Filter cup

The size and material of the filter cup are also different, and the size of the filter diameter at the bottom of the filter cup will affect the flow rate of coffee extraction, thus affecting the flavor of coffee.

The fan-shaped filter cup has the advantages of small filter diameter, slow flow rate and mellow taste; the cone-shaped filter cup has large filter diameter, fast flow rate and light taste; the wavy filter cup has a flat bottom with special wave filter paper, which makes the coffee taste the most uniform.

What is more special is the metal filter cup, which can be used without matching filter paper, so it can retain more coffee oil and taste, but some finer coffee powder may not be filtered out.

Filter paper

Some coffee lovers will try different shapes of filter paper with different filter cups to extract the flavor of different coffee. The main function of filter paper is to absorb some of the smell, fine powder and oil of coffee. Unbleached filter paper may have some paper smell.

Bean grinder

The freshest coffee is the freshest, and the grinding degree and evenness of the coffee powder are the key to affect the flavor of the hand-brewed coffee, so the quality of the bean grinder will directly affect the quality of a cup of coffee.

The most suitable powder particles for hand-brewed coffee are about the size of brown sugar. The more uniform the particles are, the more uniform the flavor of the coffee will be.

There are commercial or household electric bean grinders on the market, as well as manual bean grinders. The manual bean grinder is cheaper, small and easy to carry, but the physical exertion and grinding degree are limited.

The grinding basin in the bean grinder can be roughly divided into flat knife, cone knife, ghost tooth; flat knife belongs to use-cutting, so that the contact area is large, the advantage is fast extraction, but a double-sided blade is also easy to over-extraction; cone knife is-rolling way, resulting in thicker particles, it takes a long time to extract, but will not over-extract; and ghost teeth balance the advantages of both sides.

Of course, different brewing techniques will affect the extraction of coffee, so keep trying to find out your favorite flavor.

I hope you can learn the basic theory of hand-brewed coffee, and the function and influence of different elements such as roasting degree, grinding degree, water temperature and utensils of coffee beans, so as to find out the most suitable way to brew your own coffee.
