How to choose a flower jar as one of the necessary weapons for baristas

Professional coffee knowledge exchange more coffee bean information please follow the coffee workshop (Wechat official account cafe_style)

Many entry-level baristas pay attention to the operation skills hidden in the coffee flower, familiar with a lot of practice, but sometimes counterproductive, ineffective; from the professional barista pay attention to comprehensive aspects, such as: coffee machine, raw materials, techniques, and so on. Of course, these conditions are essential, preparation will not be easy to fail.

The flower-pulling jar is a necessary "weapon" for coffee flower-pulling. Careful baristas will find that in addition to the capacity, there is a difference in the shape of the cylinder tip on the market, so they are good at reasonable selection and use. Be able to show their flower-pulling skills in every operation. For those baristas who pursue the secret book of pulling flowers, do not focus on a certain point, but should consider it comprehensively so that you can get twice the result with half the effort.

As the saying goes: if you want to do good work, you must first sharpen its tools. Pull flower jar is a necessary "weapon" for coffee flower pull. For beginners, there are many kinds of flower jar available on the market, so how should they be chosen?

The difference between a pointed mouth and a round mouth (RW vs Tiamo):

The sharp mouth is good for fine water flow, but it should be attached to the thinner milk foam. The swinging curve of the round mouth is smooth, but the flow column is thicker.

Under the sharp mouth, the difference between a wide mouth and a narrow mouth: (RW vs Sawada HARIO)

The wide exposure reduces the collision resistance between the foam and the milk tank, and a slight swing under the thin foam can make a large convection pattern, but if the foam is thicker, there are too many bubbles injected per unit time, which is not conducive to the control of flow rate and latteart.

On the other hand, the smaller angle opening is beneficial to manually control the swing, and the small blade combination skill is better.

The difference between long mouth and short mouth: (Motta vs Tiamo)

Too long diversion groove will lead to wobble fatigue, but it is easier to accurately locate the injection point, and tulip graphics are dominant.

The difference between turning nozzles (with diversion grooves) and non-diversion grooves (Gear vs RW)

The diversion channel increases the angle of the flow column close to the liquid at the same velocity, so it is easy to dump. When there is no diversion channel, the liquid is more inclined to be injected, resulting in greater convection.

The advantages and disadvantages of a big belly (small at the top and big at the bottom):

It is easier to encircle the steam force, increase the milk beating fault tolerance rate, and is more conducive to the foaming and fusion of milk foam, but the smaller radial opening is not conducive to the production of complex latteart.

Advantages and disadvantages of different material / weight / surface treatment

Material:

Stainless steel is a good choice with fast heat conduction, stable chemical properties, corrosion resistance and easy cleaning, while copper and aluminum is slightly active in chemical properties and soft in texture, which is not the mainstream of milk tank production.

Weight:

Lighter milk tanks are more likely to sense the amount of milk foam left in the milk tanks, while heavy milk steel is less sensitive.

Surface treatment:

Teflon is a good surface treatment method, the price is friendly to the people, easier to clean, and has a certain hardness.

The paint / plating treatment is more beautiful and the price will be higher, but it is easy to fall off, wear and tear, affecting the appearance.
