The weather is getting hotter recently. For some consumers who are pursuing refreshing and cool, buying a cup of iced coffee may be a good choice. Starting this week, cold extract coffee has returned to major stores across the country, so many people will pick up a cup on the way to work and use it as their life-saving coffee for today.

However, after drinking the cold extract coffee in the cup, some consumers noticed that a layer of coffee powder had settled on the bottom of the packaging cup. Judging from the pictures displayed by customers, some packaging cups have powder spread across the entire bottom of the cup, which looks quite like a layer of unmelted chocolate sauce.

At the same time, some customers also reported that when they tried Lucky's cold extraction, they felt that the powder in the liquid was very strong, and there seemed to be some powder residue in their mouth after drinking it,"like drinking mud soup." Now that I see the sediments at the bottom of other people's cups, I realize that my feelings are not wrong.

Seeing the muddy powder in the packed cup, cold extraction enthusiasts couldn't help but frown. They said that under normal circumstances, although cold extract coffee brewed with coffee powder may leave fine powder after filtration, it is rare to have so much sediment left like Ruixing.

Moreover, judging from feedback from social platforms, many customers have received cold extract that is extremely dusty. From this point of view, some people speculate that there may be deficiencies in Lucky's cold extraction production process.

In response, a group of Lucky workers posted operation videos, saying that they were operating in accordance with the procedures given by the company. As for the large amount of fine powder deposited at the bottom of the cup, the shop assistants reluctantly said that the "culprit" of causing the powder residue mixed in the coffee liquor should be the filter bag.

Some employees said that according to the requirements of the headquarters, coffee powder needs to be poured into filter bags and added water to stir so that the powder is fully soaked in cold water. After 18 minutes, lift the entire filter bag and filter out the coffee liquor. However, due to the average quality of the filter bags equipped with the store, the fine powder can easily flow out with the coffee liquor. If the clerk squeezes the filter bag during filtration in order to increase the filtration speed of coffee liquor, only more fine powder will be mixed into the liquid.

Therefore, in order to ensure the taste of cold extract, some stores have no choice but to add an extra filter bag during production to reduce the fine powder in the coffee liquor. However, this practice undoubtedly reduces the filtration speed of liquids and increases the production time of cold extraction. It is a time-consuming and laborious task for migrant workers.

Hearing the explanations of Ruixing workers, netizens believed that since the crux was the filtering tool, the brand should use a finer filter based on employees 'feedback, or adjust the thickness of the coffee powder to avoid leaving too much fine powder in the cold extracted coffee liquid.

But it is worth mentioning that compared with the kind suggestions of customers, Lucky employees prefer that consumers can call the customer service phone to complain about this product. In their view, as long as they receive negative reviews from most customers, Luckin may remove Leng Cui from its shelves due to poor market feedback. In this way, migrant workers do not have to spend 18 minutes a day making cold extract, nor do they worry about stores receiving complaints about the precipitation of fine powder in drinks.
