Hand brewed coffee, the control of “water flow” is quite crucial! If the water flow fluctuates between large and small, it can cause insufficient or excessive water intake in the coffee powder, making the coffee full of sour and astringent flavors, and also easy to produce mixed flavors. To ensure stable water flow into the filter cup, the quality of the hand drawn teapot has a significant impact.
01 Forging Material
Because temperature can affect the dissolution rate of soluble substances in coffee powder, we generally do not want a significant difference in water temperature in the hand brewing pot during the brewing process. So a good hand brewed pot should have a certain insulation effect, at least during the 2-4 minutes of brewing coffee, try to control the temperature difference of the water at around 2 degrees Celsius.
02 Pot Capacity
Before the water injection operation, most hand flushed pots need to be filled with more than 80% water. Therefore, when choosing a hand flushed pot, it is best not to exceed 1 liter in capacity, otherwise the pot body will be too heavy, and it will be tiring to hold and affect the control of water flow. It is recommended to use a hand drawn teapot with a capacity of 0.6-1.0L.
03 Wide pot bottom
During the boiling process, the water in the coffee pot will gradually decrease. If you want to control the water pressure steadily and thus stabilize the water flow, the hand pot needs a wide bottom that can provide the corresponding area. Stable water pressure can help coffee powder roll evenly in the filter cup.
04 Design of water outlet pipe
Hand brewed coffee uses the impact force of the water column to achieve the extraction effect, so the hand brewed pot must be able to provide a stable and uninterrupted water column. Therefore, the thickness of the water outlet pipe is very important, and too thick can lead to difficult control of the pouring water flow; If it is too thin, it is impossible to provide a larger water flow at the appropriate time. Of course, for beginners and enthusiasts, choosing a hand watering pot that can keep the water flow constant can also reduce cooking errors appropriately. However, as your cooking skills improve, you may need a hand watering pot that can adjust the size of the water flow more.
05. Design of spout
If the design of the water pipe affects the thickness of the water flow, then the design of the spout affects the shape of the water flow. In order to reduce the chance of repeated water intake of coffee powder in the filter cup, the water column generated by the hand drawn kettle must have a certain degree of penetration. This requires the design of the spout with a wide water outlet and a sharp shape at the end of the tail section to form a water column that is thick at the top and thin at the bottom, with penetrating power. At the same time, in order for the water column to provide stable penetration, the design of the spout should also ensure a 90 degree angle with the water column during water injection. There are two types of spout that are relatively easy to form this type of water column: narrow mouthed spout spout and flat mouthed spout spout. Crane billed and duck billed pots are also possible, but they require advanced control skills. So it is recommended that beginners start with the fine mouthed teapot.
Experiments have shown that the general stainless steel coffee pot spout uses drip water to supply water, forming a droplet like shape with a relatively concentrated weight at the bottom. When it comes into contact with the powder layer, it has a certain impact force and cannot spread evenly. On the contrary, it increases the probability of uneven water flow in the coffee powder layer. However, the duckbill pot can form water droplets when it comes out of the water. Compared to water droplets, water droplets are a uniform spherical shape that can evenly spread outward when in contact with the powder layer.
summary
Based on the above points, everyone can choose a suitable hand pot according to their own needs and budget, and make a delicious cup of coffee for themselves, family, friends, or guests!
