Everyone! So! Zhou! Know!!! Dirty is a very unique milk coffee. Although its making materials can be said to be the same as iced latte, because of its different making methods and drinking methods, it gives it a completely different tasting experience from regular coffee. Not only that, it will also be more suitable for creation than other coffees, so creative features about Dirty have always emerged one after another.

And forget whether it started last year or the year before last, a coffee called "-86 ° C Dirty" has become popular on the Internet. Almost all posts or merchants about-86 ° C Dirty have received a lot of traffic. Even today, the popularity remains high. So this attracted the curiosity of many friends: "What is this-86 ° C Dirty? What is the difference between it and ordinary Dirty? Is it really that good? "

So today Qianjie plans to come and share with you what the origin of this wildly popular-86 ° C Dirty is.

What is-86 ° C Dirty? Before introducing-86 ° C Dirty, as usual, I would like to briefly introduce Dirty first. Dirty coffee, also known as "dirty coffee", is an Italian milk coffee as introduced in front of the street. The raw materials for making regular Dirty are frozen milk and thermal concentration. During production, we will use a specific method to allow the thermal concentration to float on the frozen milk to create layers. The purpose of layering not only gives the coffee a better appearance, but also creates a unique experience.

With just one big gulp when tasting, we can drink hot concentrate and iced milk at the same time. Since concentrate and milk did not blend at the beginning, we can enjoy the double contrast experience of temperature and taste when drinking it. The ice and sweetness of milk, the concentrated heat and bitterness, and the layers can be said to be very rich. It is precisely because milk and concentrate are separated that Dirty coffee has more options than other coffees. The so-called-86 ° C Dirty does not mean that the temperature of Dirty is-86 ° C, nor does it mean that the cup used by Dirty is-86 ° C, but that the cup used by Dirty is stored in a refrigerator at-86 ° C. Some friends may want to say when they see this, isn't that the-86 ° C cup used?

NoNo, this is wrong. The reason why Qianjie has to be distinguished in this way is that although the refrigerator used can make the storage environment reach-86 ° C, under the influence of many factors, the storage environment of the refrigerator may not always reach the target temperature, such as opening and closing when taking out the cup. Even if it can reach-86 ° C, it will start to warm up after the cup leaves the refrigerator, and it cannot reach-86 ° C when making, so a rigorous explanation is that a cup stored in a-86 ° C refrigerator is made of Dirty. But even so, the temperature of the cup has an extraordinary low temperature due to the extremely low temperature freezing. What is the difference between the Dirty made from such a cup and the regular Dirty?

Publish the answer! There will be two advantages. The first is that there will be a more sharp contrast between milk and concentrate. Because the temperature of milk will drop further due to the influence of the cup, the contrast in the temperature of-86 ° C Dirty will be more obvious at first than that of conventional Dirty. After all, conventional Dirty is usually made with refrigeration. Secondly, it will be more interesting. Because the temperature of the cup is very low, the milk that comes into contact with the wall of the cup will quickly frost. After drinking the coffee, you can dig it with a spoon and eat it, making the experience more unique. (But the milk cream doesn't have much flavor. After all, the main ingredient in forming the cream is water)

But ~~~ Yes, there are also shortcomings. The first is that the best tasting time for this cup of-86 ° C Dirty will be shorter than that of a regular Dirty. The reason is also simple. The low temperature of the cup will also affect concentration. So if you don't start tasting it when it's ready, you won't be able to get a very sharp contrast in temperature. Secondly, the taste and taste! As Qianjie often shares, the sensitivity of our taste buds to taste will be affected by temperature. Too high or too low the temperature will reduce our ability to perceive taste, and then too low the temperature will also reduce the density of milk. The taste will become thin. Therefore, when making-86 ° C Dirty, the milk used by the store will be a thickened version, and its concentration and taste will be stronger than that of regular fresh milk. The purpose is to reduce the impact of too low temperature on the taste and taste. Therefore, if you plan to make-86 ° C Dirty at home, it is best to use a stronger milk.

Perhaps at this time, a friend said that there was no refrigerator in his house that could lower the temperature to-86 ° C, so he couldn't do anything. But in fact, the freezer compartment of a regular refrigerator can achieve a similar effect, and the difference in drinking is really not much. We just need to set the temperature in the freezer to a minimum, then put a slightly thicker cup to freeze it overnight, and the next day you can get a cup that is extremely cold and can freeze cream.

Qianjie had done such an experiment before. A cup was frozen in the refrigerator one night in advance and then taken out the next day. The Dirty made with it did have a small amount of cream after drinking it. It's just that the milk you use when making it should be a little stronger, as Qianjie said earlier. There are not many requirements for coffee beans, but if you want to highlight the sweetness of milk or make the contrast more distinctive, then you can choose medium to deep and deeply roasted coffee beans, such as the Qianjie Classic in the Qianjie Bean List.

Because the unique charred aroma of deep-roasted coffee beans is completely opposed to the sweetness of milk, by using deep-roasted coffee beans, we can further widen the gap between milk and concentrated flavors, and at the same time their flavors will also become more prominent because of the other party's foil. In one bite, you will first find the concentrated aroma, alcohol and warmth extracted from the classic Italian blend. It has the flavors of chocolate, caramel, nuts and cream. The taste is mellow and warm. This is followed by the sweetness and coldness of milk, which contrasts sharply with concentration. If you drink quickly, you can see a little cream in the glass.

So the above is all the content shared on Qianjie this time.-86 ° C Dirty is indeed a very unique experience. Interested friends can try it for themselves ~ By the way, answer the last and most concerned question of friends: The cup will not stick to your mouth ~~
