Still struggling with what kind of cooking utensils to buy? See a dazzling array of filter cups, cooking pots, bean grinders. I don't know how to choose? Never mind! An article in Qianjie takes you to choose coffee brewing utensils suitable for beginners!

-selection of coffee grinder-

Bean grinder is very important! Bean grinder is very important! Bean grinder is very important! The price of the bean grinder on the market is also "colorful", from dozens of manual bean grinders to tens of thousands of electric bean grinders. Many buddies who have just started brewing coffee will think that the bean grinder is very expensive, so they casually buy a cheap one, or a spiral blade grinder that is not a coffee grinder.

It is certain that the price determines the quality of the bean grinder. If it is only daily cooking rather than store products, Qianjie suggests that the budget of the hand grinder should be set at about 50-2000 yuan, while the budget for the electric bean grinder should be set at about 1500-5000 yuan.

The coffee grinder is expensive. Where is it? Grind the cutter head!

Knife head as the most important part of the bean grinder, different knife heads directly affect the diameter distribution of coffee powder, that is, it determines whether the coffee powder is uniform after grinding, and the degree of grinding has a great influence on the taste of coffee. At present, the common types of cutter head can be divided into conical knife, flat knife and ghost teeth. Among them, the vertebral knife and ghost teeth are only used for the grinding of hand coffee.

Cone cutter head: coffee beans are ground into particles by grinding, so its shape is mainly block. Generally used for hand grinding, because it is in the form of "grinding", coffee beans will appear a large number of dust-like fine powder when they are crushed and burst. The normal coffee particles are also irregular blocks, but tend to be uniform as a whole. The cone knife close to the granule leads to a longer water absorption path and longer exposure to water, so the initial release of less soluble matter concentration will not be too high, but it is not easy to produce miscellaneous taste and astringent taste when xylem absorbs less water for a long time.

Ghost tooth cutter head: coffee beans are ground into particles by grinding, so its shape is mainly close to the sphere. But also because a coffee bean can be ground into several small particle spheres, then the grinding sphere will produce more leftovers (fine powder). But the overall difference between large particles is the smallest.

-purchase coffee grinding correction screen-

The degree of grinding directly affects the taste of the whole cup of hand-brewed coffee, so it is very important to find the right degree of grinding. Qianjie noticed that the primary reason why many enthusiasts do not do well at home is that the degree of grinding is not good-- the grinding is too fine, the taste is easy and bitter and astringent, and the grinding is too rough to produce the flavor.

It is recommended that the grindability of hand-brewed coffee in Qianjie is medium grinding thickness to medium thickness. At present, coffee bean grinders on the market have different grinding calibration standards, and there is no one, so Qianjie suggests buying a 0.85mm No. 20 standard sieve for screening.

The pass rate of grinding thickness of shallow roasted coffee beans is about 75% and 80%, and that of deep roasted coffee beans is about 65% and 70%, respectively.

-the choice of hand-punching pot-

In addition to the filter cup, the style of the hand flushing pot is also many, and many novice friends rush to flush the color of the pot when they don't know which one to buy. (Hey, wrong focus!) We should pay attention to the capacity of spouts and pots! The novice in Qianjie is advised to choose a gooseneck pot with a thin mouth. What does it look like? Look like this.

The capacity of the hand pot determines the center of gravity when cooking, and the center of gravity also feels the stability of the flow of water. The hand pot with too small capacity will lack the center of gravity and float very much when filling water; although the center of gravity of the hand pot with large capacity can stabilize the flow better, it is not suitable for small friends. Therefore, Qianjie suggests that it is more suitable to choose a hand punch with a capacity of 500-600ml.

Do you choose a temperature-controlled hand flushing pot or an ordinary hand flushing pot?

You can choose either one. You can buy a thermostat flushing pot with a sufficient budget. If the budget is relatively small, you can choose an ordinary hand pot, and then buy a digital thermometer.

-the choice of cooking filter cup-

There are so many types of coffee filter cups on the market that people are dazzling, and different styles of filter cups have different brewing effects. Before struggling to buy which filter cup style, first get a V60 filter cup, there is no single product coffee beans can not be washed by the V60 filter cup!

The name of the V60 filter cup comes from the cone-shaped design with a 60-degree angle, which guides the water to the center and prolongs the contact time between water and coffee. The bottom large aperture filter design allows you to control the flavor extraction time of coffee by changing the size of the water injection. The spiral ribs (exhaust trough) allow air to be discharged upward from all sides, maximizing the exhaust process of coffee powder.

-selection of filter paper-

The shape and size of the filter paper determine the fit degree between the filter paper and the filter cup. When the filter paper with mismatched shape can not fit perfectly with the filter cup, it is easy to cause the gap between the filter paper and the filter cup, which changes the diversion effect of the filter cup and leads to the negative effect of unequal coffee extraction. So when buying filter paper, you should look at the model of the filter cup, and then buy the same type of filter paper.

Choose log filter paper or bleached filter paper?

Log filter paper refers to unbleached filter paper, which is light brown and smells like paper. Bleached filter paper refers to the bleached filter paper, which is white and has no obvious paper smell. On the question of how to choose log filter paper and bleached filter paper, Qianjie is more inclined to bleach filter paper. Because the smell of the bleached filter paper is not obvious, it will not affect the taste of the coffee.

You may be worried about the toxicity of bleached paper. In fact, the famous coffee filter paper brands now use advanced enzyme bleaching. Unlike traditional chemical bleaching, enzyme bleaching uses bioactive enzymes for bleaching. It is widely used in the field of medicine. Therefore, in the purchase of coffee filter paper must choose a large brand, the price is reasonable, some too cheap filter paper regardless of material, size and bleaching technology can not be guaranteed.

-selection of electronic scales-

Qianjie suggests buying a fast-display electronic scale with timing function, or directly searching the hand-made coffee electronic scale to buy.

-the choice of sharing pots-

Qianjie suggests that when choosing a sharing pot, it is recommended to see whether the pot itself is heat-resistant, instead of buying a pot with poor quality when it looks good. When brewing coffee, it is easy to crack, so you can't buy a sharing pot for petty gain.
