Guest: "Boss, have a drink of dirty!"Front Street: "..., no, Dirty doesn't make hot dishes..."In daily life in coffee shops, such a conversation can be said to be common. Because Dirty is made from the same ingredients as latte, cappuccino and other milk coffees, many friends will think that Dirty also has two different versions: cold and hot. After all, in order to better meet the needs of guests, as long as conditions permit, coffee will appear in a version opposite to its "original attributes".Just like latte, kabob, Americano, hand-brew and other coffees were only hot at the beginning. As the number of coffee drinkers increased, the demand for iced drinks increased. Products such as iced latte, iced Americano, iced hand-brew and other products with the opposite temperature to the original products came into being. Even Australia Bai, which is often ridiculed, has an ice version in some places. Only Dirty still only has one version."Why is there no hot Dirty? Is it because we can't make it?" Some friends will ask Front Street the same question after learning that there is no hot Dirty.Regardless of the difficulty of making it, hot dirty can still be made, and Front Street has shared it many times. Because the ingredients for making Dirty are nothing more than milk and concentrate, as long as we slightly change their temperatures, a cup of hot Dirty is ready. But the main reason why no coffee shop sells hot dirty food is that hot dirty food is very troublesome to make, and at the same time...(not tasty)......What does regular Dirty look like? First of all, it is a combination of iced milk and warm concentrated milk. The two are independent of each other due to their density, so when we take a big sip, we can taste two different extreme experiences in sequence. First the heat and bitterness of the concentrate, then the coldness and sweetness of the milk.Although the temperature and taste of the two materials will "conflict" in our mouths, they are not obtrusive. Then they will fuse in the mouth and transform into another brand-new experience. It can be said that the levels are very rich. Although Hot Dirty can also produce the same contrast effect, its performance can be said to be very abrupt.icemilk,hotConcentration is the only component of traditional dirty. If we want to make a cup of "hot dirty" with the opposite temperature, we need to beat the milk intohot, concentrated intoiceof. The difficulty of achieving this is not very high. Milk is heated by any heating source and concentrated by usingstainless steel ice ballCool down over ice.Friends who want to try it can also follow the steps below. First, we heat the milk to 65°C, and then pour it into a prepared dirty cup that has not been refrigerated. The amount of milk added in Front Street here is 160ml which is usually used to make traditional dirty.The concentration is the same as usual, using 20g of powder and extracting 40ml of coffee liquid in 30 seconds. But what is different from usual is that Front Street added two stainless steel ice balls on the cup, so that the espresso will cool down when it comes into contact with the ice balls, and what ends up falling on the milk is the espresso with a lower temperature.But it should be noted that since the temperature of the milk in the lower layer changes from cold to hot, the effect of layering will not last long. The reason why traditional dirty milk can maintain its layered state for a long time is because the density of ice milk is high and it can hold the concentration. When the temperature of the milk becomes hot, the concentration will quickly merge with the milk because the density decreases. So after making it, we need to taste it as soon as possible to experience the layering effect.If the coffee beans you use are not very darkly roasted, Front Street believes that everyone can clearly feel the abruptness mentioned by Front Street when tasting it.When the coffee beans are not roasted very darkly, the extracted coffee will be acidic. However, it is difficult for us to capture the sour taste in coffee due to the masking of bitter substances and suppression by the high temperature of coffee.
But because the espresso in "Hot Dirty" is cold, the temperature is not that high, so our taste buds can taste the sourness in the coffee very well. Therefore, when we drink coffee, the first thing we feel is a relatively concentrated and obvious acid. Although the sourness is not very sharp due to the uniform extraction, it does not match the taste of milk, is rather abrupt, and does not form a stunning contrast.In addition to the mismatch in taste, the texture of the whole cup of "hot dirty" will not be as good as traditional iced dirty. This is because of milk! Because milk accounts for 80% of a cup of dirty coffee, it can be said to dominate the taste of the entire cup of coffee.Compared with hot milk, the experience of drinking iced milk is actually more comfortable, which is related to its temperature. Because it is opposite to the temperature in the mouth, ice milk will taste smoother and more refreshing than hot milk through interaction, which gives coffee a more excellent texture. Therefore, compared to Dirty made with ice milk, Dirty made with hot milk will be much inferior. After taking a sip from Front Street, the concentrate and milk were almost integrated.From the above, we can know that the reason why coffee shops do not sell hot dirty is mainly because of these three points: ① It is more troublesome to make; ② The taste and texture of the coffee are not outstanding; ③ The layering effect lasts for a very short time, and the "hot dirty" may have turned into a cup of hot latte before it is served to the customer.
