Can you imagine cockroach bits and barley worms floating on the surface of a cup of coffee? The "Bug Special" series of drinks recently launched by Beijing's All Things Museum has sparked heated discussion on social platforms. One product, which sprinkles processed dried insects directly onto the surface of the coffee, has prompted netizens to say they dare not try it due to its strong visual impact. The museum said that all insect ingredients are purchased from traditional Chinese medicine pharmacies and meet food safety standards. The core purpose of developing this 45-yuan drink is to break the public's stereotype of cockroaches. Staff revealed that current daily sales are about a dozen cups, with consumers mainly curious young people, while many parents with children find it hard to try because of psychological acceptance issues.

A recent video claiming that coffee is allowed to contain 10% cockroaches has caused concern among many coffee lovers. The video mentions that insects often cannot be completely separated from coffee beans, so they go through the roasting and grinding process along with them. Most food regulatory agencies do allow a certain proportion of insect content in food. Cockroaches themselves are rich in protein and pose no direct harm to the human body, but people with allergies need to pay special attention to pre-ground coffee powder. This article will discuss this topic to help everyone view the issue of insects in coffee rationally, while continuing to focus on professional coffee knowledge and recommendations for high-quality coffee beans.

In the coffee consumer market, Arabica and Robusta are the two major mainstream varieties, while Liberica is relatively rare. Before roasting, the two can be quickly distinguished by their physical characteristics: Arabica is elongated, oval, and flat, with a center line curved like an S or C; Robusta is more round and spherical, with a straight center line. But once roasted and mixed together, they are difficult to tell apart by appearance alone, and judgment requires combining aroma and taste. Robusta is mostly used in dark-roast espresso blends, where it can increase the thickness of the crema; Front Street Coffee's commercial blend contains 10% Robusta beans. Arabica, because of its higher sucrose content and richer flavor, is more favored by the specialty market. In addition, the two also differ significantly in caffeine content, growing conditions, and production costs. [more…]

The content of defective beans directly affects coffee quality and grade classification.

Honey Scented Black Tea is a highly representative fully fermented tea from Taiwan, with major production areas covering New Taipei City, Hualien, Nantou, Chiayi, and other places, and the production season concentrated from May to September. Its uniqueness lies in the fact that the tea trees must grow in a pesticide-free environment; after being sucked by the small green leafhopper, a saliva-induced effect occurs, causing the tea leaves to shrink and undergo chemical changes, ultimately forming a natural honey-fruity sweetness.

I've tried quite a few Mandhelings, but aged Mandheling is a special existence that requires time to craft. It draws on the idea of Indian monsoon coffee: the green beans must be quietly aged in a ventilated, cool warehouse environment for 24 months, during which they are regularly turned to prevent mold and insect damage, consuming a great deal of labor. After this treatment, the beans' acidity is greatly reduced, their body is significantly improved, and their sweetness carries a honey aroma, with a flavor profile completely different from fresh beans. This time, Front Street Coffee used Sumatra Typica as the sample, roasting it medium-dark with 550g batch size in a Yangjia 800N roaster, and completed brewing with a KONO dripper at 88°C water temperature, ultimately presenting a cup that interweaves herbs and caramel. This article will fully break down the story behind this unique Mandheling, from the principles of the aged processing method, changes in the appearance of the green beans, details of the roasting curve, to the brewing parameters.

Recently, a consumer reported finding a whole black insect at the bottom of a cup of "Orchid Latte" purchased at a Chayan Yuese store on Nanjing Station Square, just as they were about to finish the drink.

After reviewing surveillance footage, the store said there were no abnormalities in the production process, while the brand responded that the insect might have entered the cup after the customer left the store. A refund has been issued, and the brand is continuing to communicate with the customer. The incident has once again sparked discussion among consumers about the brand's practice of not proactively providing cup lids. [more…]
