Make your own iced coffee, and you can drink it at home with time!

Most people who start to try "iced coffee" have accumulated some coffee tasting experience. Different from hot water extraction or high pressure extraction,"ice drop coffee" is extracted through ice water at low temperature, which can obtain a more fragrant and smooth coffee flavor.

Deep-roasted beans are the most suitable for "ice drop coffee" material, their favorite varieties or blend coffee, can be used to try. Brand coffee beans are not necessary, actually tried a variety of different coffee beans, all very good to drink.

The first step is to grind the beans into powder. The amount required is about 8.5 to 9 minutes full of the coffee powder container in the ice drip pot. The demonstration set uses about 6 tablespoons.

The powder is of medium or medium fineness, the same fineness as used for drip or siphon. Take the Hario Hand Grinder (MSCS-2TB) in the photo as an example. The thickness position I use is to turn to the tightest position and then turn it back 6 steps.

By the way, this Hario is equipped with ceramic blades. The original factory emphasizes that this design is less prone to heat, because the heat generated during grinding beans may affect the taste of coffee. Another advantage is that it is easy to wash and relatively easy to clean.

All the equipment is in place, and in the middle is the ice drip coffee pot.

The main structure of the ice drop coffee pot can be divided into four parts, namely, the upper pot for ice cubes or ice water, the container for coffee powder and the filter device, the lower pot for receiving coffee extract, and the fixed bracket. The bottom of the pot will have a rotatable small faucet, so that ice water falls on the coffee powder at a certain rate. The whole process is like a chemical experiment, which is quite novel and interesting!

The upper pot has an attached lid to keep dirt out. Cold winter weather, it is recommended to use half ice and half water. Summer temperature is high melt fast, ice mainly add a small amount of water or put pure ice is more suitable. The actual proportion, please adjust according to the ice melting condition.

Ice water starts dripping, coffee powder gets wet. It takes a long time to change from water to the first drop of coffee, and a sneak step is to pour some ice water directly or leave the tap open for a while, which can reduce some time.

After filling the coffee powder, you can tap the edge of the container a few times to make the powder more concentrated, but do not press it tightly. (Note: If it is too tight, the extract may not flow out easily or even drop out completely)

If necessary, a spoon can be used to press down the powder floating on the surface of the water, so that all coffee powder can be fully soaked.

Because of the thermal expansion and contraction relationship, the flow of small faucets may change after a period of time. When the ice water does not drip out or the flow rate is very slow, it should be adjusted appropriately.

Soaked coffee powder can have a muddy or sticky feel, as shown in the photo below.

Coffee extract began to drip into the pot, this time dark brown, you can visually tell its concentration. As time passes, the coffee extract will become lighter and lighter, but it doesn't matter,"ice drop coffee" is originally slowly mixed from strong to weak drop by drop, the final liquid is the natural average concentration.

In case the extract cannot flow out, it may be too tight or blocked by air. Try moving all the wet coffee powder from the container to a bowl, washing the container and strainer with boiling water, and pouring back the wet coffee powder. I always solve this problem this way.

As mentioned earlier, the small tap at the bottom of the upper pot is the main gate for the flow of ice water, and in fact the ice itself is also the main gate, because the melting state of the ice will affect the amount of ice water and the speed of outflow. If ice cubes are submerged in water, they will melt faster. Conversely, if ice droplets melt faster than ice cubes, it will actually take longer for ice to drip out, so the two can be used together.

There is no special ice drip coffee pot, after understanding its operation principle, the same can be DIY, as long as there is ready-made drip filter equipment, can be simply modified. For example, ice drops can also be made by placing ice cubes directly on a drip filter containing coffee powder and allowing the ice to slowly melt into water (the melting rate is the flow rate).

This group of ice drop coffee pots takes about 3-4 hours to complete a pot (actually about 70%). In fact, it takes many times longer than hot water extraction. It is really "condensing fragrance with time." But it's worth the effort. A bite of your tongue will tell you what's different. After dripping, you can drink it directly, or bottle it in the refrigerator, which will have a better flavor. When drinking, you can mix ice water to adjust the concentration, you can also add fresh milk, completely with their favorite.
