That golden layer of crema on top of espresso, which Italians call Crema, is an important visual indicator for judging the quality of a cup of Espresso.

When the crema is missing, thin, pale, coarse and foamy, or clumpy, it often points to specific problems with bean freshness, roast level, equipment performance, or extraction parameters. Starting from Front Street's extraction experience, this article sorts out the causes and evaluation criteria of Crema, helping you identify the root of the problem by observing the form of the crema, so you can make a cup of espresso with a rich, dense crema.

Recently, a Heytea store in Xi'an Joy City was exposed by consumers for poor hygiene conditions in its preparation area, quickly sparking heated discussion online. According to the whistleblower, the store's counter, refrigerators, juicers, and other equipment were covered in milk tea stains, materials were scattered around, and there was even a strong smell of sour rags and rotten fruit. Upon verification, the store was a directly operated location rather than a franchise, which further raised public doubts about Heytea's food safety management. Heytea later issued an apology and announced that the store would be closed for rectification, while also strengthening employee training and optimizing operational standards. This incident has once again pushed the issue of hygiene control in chain tea beverage brands into the spotlight and serves as a reminder for consumers to pay attention to the transparency of beverage preparation environments.
