What roasted coffee beans are suitable for Ice-Drip Coffee? What proportion is the most suitable grinding time and concentration for cold extracted ice drop coffee?

Compared with the past, the popularity of coffee in China has greatly increased. In addition to tasting drinks, many friends have begun to purchase coffee equipment and make coffee at home. But there are always some products that are still niche products on the homemade menu when coffee is already very popular. For example, ice drop coffee, not many friends will make it at home.

Ice-drop coffee is one of the cold extract coffees. The so-called ice drop means that this coffee needs to be made with ice water dripping. One of the reasons why homemade ice drops are relatively small is that the audience of ice drops is small. Another reason is that ice drop coffee is time-consuming and labor-intensive, and a dedicated ice drop coffee pot is required. Although the price of the ice drop pot is not expensive, many friends, including Qianjie, do not make ice drops frequently. The reason is as mentioned above. It is troublesome to make. If you don't have a friend who particularly likes ice drop coffee, then there is a high probability that you will not be able to escape the fate of eating dust in the cabinet or corner after you buy it. Therefore, people rarely buy ice drip pots and make their own ice drip coffee at home. When they want to drink cold extract, they usually soak it directly.

However, iced coffee still has some advantages that cold brewed coffee does not have! For example, it will taste cleaner when drinking, and the aroma of coffee and the flavor of fermentation will be stronger. Therefore, ice-drop coffee is also a favorite for some friends. "Is there any way to make ice-dripping coffee at home without an ice-dripping pot and without having to carry out too cumbersome operations? "Friends often ask Xiangjie this way when buying beans. Of course there is! And there are quite a few. In recent years, Qianjie has often shared some "shady" ice drop making methods. These methods are without exception, very simple, and do not require the use of a professional ice drop pot, as long as you have a filter cup. It just happened that the weather has recently returned to warmer temperatures, and it has reached a temperature where you can drink cold drinks unscrupulously (referring to Guangdong), so today Qianjie came to share some "evil repair" methods that can make your own ice drop coffee at home ~

Be reasonable... To be reasonable, although the ice drip pots on the market all seem to have very complex compositions, in fact, their core device is the flow restriction valve, which can control the filtration of ice water drop by drop.

The flow restriction valve is used to control the dripping speed of ice water, so that ice water with low extraction efficiency has enough extraction time to dissolve more flavor substances in the coffee. The other ingredients of the ice drip pot are either used to hold coffee powder or to hold ice water and coffee liquor. These functions can be achieved by a filter cup, sharing pot or other container. So in theory, as long as we can control the dripping speed of ice water and then let the ice water drip on the coffee powder, we can make ice dripping coffee.

To do this is actually very simple. Instead of using ice water, we use ice cubes and let the ice cubes melt naturally at room temperature! Without adding water, the ice cubes will melt slower than everyone thinks. We just need to place the ice cubes on top of the coffee powder and let the melted ice water extract the coffee powder, and we can complete the ice drops. The extraction process of coffee.

There are many evil methods to fix ice drop coffee on the Internet, but without exception, they all use this logic to make it. The only difference is that the carrier of the ice cubes is different, so you can decide the specific equipment and method based on the tools available in your home. So before introducing specific practices, Qianjie will first share the coffee beans used and specific parameters. These two factors determine whether a cup of coffee tastes good or not, which is still very important.

What kind of coffee beans are suitable for Ice-Drip Coffee? In the same way as other extraction methods, what coffee beans are suitable for ice drop coffee mainly depends on your preference. If you want to make a cup of ice-drop coffee with sweet and sour taste, full of fruit flavor and fruit wine aroma, then the choice of coffee beans can be sun-exposed, honey treated, anaerobic treated and other heavily fermented coffee beans that are lightly baked! For example, the Qianjie Essi Huakui, the Boundary Manor Xizhao, Kenya Small Tomatoes, etc. in the Qianjie Doudou List are all quite good choices;

If you want to make ice drop coffee with a slight floral flavor and a softer taste, you can choose to wash it or other medium and light roasted coffee with floral flavor. For example, the Front Street bean list includes Front Street Panama Poquet Rose Summer, Yegashefi Goddin, Costa Rica Mozart, etc.; if you want to make a cup of ice-drop coffee with mellow and weak acid flavors such as chocolate, nuts, cream, etc., then the choice of coffee beans can be medium and deep roasted coffee beans. For example, the Front Street Sumatra Golden Mantonin, Brazil Queen's Estate, or Jamaica Blue Mountain Coffee in the Front Street Bean List.

What extraction parameters should be used for ice drop coffee? After selecting the coffee beans, we need to determine the extraction parameters we use. However, the extraction parameters of ice drop coffee are actually not that complicated, because the grinding degree can directly follow the grinding degree of hand-brewed coffee, and then the water temperature does not need to be controlled by us. The only things that need to be paid attention to are the ratio of powder to liquid and the time. We can make two choices about powder-to-liquid ratio and time. If you want to add ice cubes to maintain the low temperature of the coffee while drinking ice-dripping coffee, then the concentration of the coffee should be stronger. If we want to make high-concentration coffee, we need to use less water and take a long extraction time; but if you want to drink it directly after making ice-dripping coffee, then the coffee concentration will not be so high, and you can have more water., the time can be shorter.

Take Qianjie as an example. Qianjie generally makes ice-drop coffee with high concentration. Because you want to add ice when drinking it, the ratio of powder to liquid is 1:10, and the extraction time of 50g coffee powder is about 4 hours.

The "evil repair" version of Ice-drop coffee is very simple. We need to prepare one/two filter cups, ground coffee powder, filter paper, ice cubes, sharing pot/any container, and sealed container. (If you only have one filter cup, you can also choose to spread a layer of filter paper on the coffee ground and put ice directly on it. If you don't have a mold for freezing ice cubes, you can also directly take a bottle of mineral water to freeze it and hang it on coffee powder to drip filter... It was very popular last year.) So Qianjie here uses Qianjie Boundary Estate·Xizhao, the Qianjie bean list for a demonstration. The ice drop coffee made with it is sweet, sour, and has a strong aroma. It has grapes, apricots, and passion fruit flavor. It's really delicious.

Since the filter cup cannot hold too much coffee powder, if you choose to lay ice directly on the coffee powder, the amount of powder used needs to be reduced appropriately to about 25g. If you use two filter cups, the amount of powder can be around 30g. (01 V60 is used here, and the amount of powder in other filter cups needs to be adjusted appropriately)

The method is very simple. First, we put filter paper into the filter cup and moisten it, then add coffee powder and moisten it again. The purpose of wetting coffee powder is to "connect" the powder to the powder (capillary action), so that subsequent ice water can be extracted more evenly.

After getting wet, we spread 2 pieces of filter paper, preferably enough to cover all the coffee powder. (Also wet)

Then, we put the right amount of ice on the top./If you use two filter cups, you can put ice in the second filter cup and remember to put filter paper on it.

After that, we just need to wait for the ice to completely melt and extract the liquid weight of the target, then we can remove all filter cups and end the extraction. But at this time, the production of ice-drop coffee has not yet been completed, so we need to transfer the coffee into a sealed bottle and place it in the refrigerator for cold fermentation. By refrigerated fermentation, coffee can develop a stronger aroma. Generally, Qianjie recommends fermentation for 8 hours. When the fermentation is over, we can take out the coffee and start to enjoy the delicious ice drop coffee ~
