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.

Recently, a consumer selecting pastries at a Nayuki store in Guangdong noticed over a dozen small white insects flying inside the glass cabinet where freshly baked bread was stored. Although the staff used packing bags to shoo the insects away, they did not discard the potentially contaminated bread, prompting the customer to immediately abandon the purchase. The post quickly sparked discussions among netizens, with some expressing understanding due to Guangdong's humid "hui nan tian" climate, while others pointed out that insects appearing in Nayuki's baking cabinets are not an isolated incident, and the brand should strengthen protective and disinfection measures. Food safety is no trivial matter; after Nayuki's return to the baking sector, it is even more crucial to heed consumer feedback and ensure the quality and hygiene of freshly made products. [more…]

Many coffee enthusiasts have come across bloggers sharing their experiences with bean sorting before brewing. The main purpose of sorting beans is to remove defective beans that carry negative flavors. This article focuses on this topic, systematically outlining the types, causes, and identifying characteristics of common coffee defects, including moldy beans, insect-damaged beans, black beans, and the more unusual quaker beans, while explaining their specific impact on coffee flavor. It also addresses a practical question: if the chosen merchant is reliable enough and the beans have undergone multiple rounds of sorting before and after roasting, is it still necessary to sort beans by hand yourself? Drawing on Front Street Coffee's sorting process and a 15g Panama Boquete Geisha as an example, the article offers a useful reference answer. [more…]

Recently, a netizen exposed the appearance of live insects inside the bread cabinet of a Nayuki Tea store in Guangzhou, sparking yet another wave of public concern over food hygiene among tea beverage brands. The store attributed the problem to the double-door design, which allows customers to open the doors themselves and lets insects slip in—but bread crumbs on the cabinet door tracks equally exposed lapses in daily cleaning. Notably, this is not the first time Nayuki has been embroiled in a food safety scandal; as early as 2021, media undercover investigations of its back kitchen exposed hygiene hazards such as cockroaches. Although the brand claims to hire professional pest control companies monthly, complaints about insects in bread cabinets remain common on social platforms. Food safety is no small matter. Front Street Coffee believes that only by relentlessly addressing every hygiene detail can tea and coffee brands win consumers' long-term trust. [more…]

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. Unlike past food safety complaints, many regular customers said they were not surprised—to preserve the texture and appearance of the cream top and milk foam, Chayan Yuese typically serves drinks without lids, leaving them open, so the risk of insects falling in has always existed. 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…]

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 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.

Recently, a consumer in Hangzhou, Zhejiang, posted on social media claiming to have疑似 found fragments of an insect carcass in a takeaway milk tea from the well-known freshly made tea drink brand KOI. The consumer and the brand failed to reach an agreement after multiple communications over compensation and an apology, and the consumer has filed a complaint with 12315 and insists on pursuing legal proceedings. KOI responded that neither the store surveillance nor inspections by the market supervision department found any foreign object entering the drink, and that the strainer hole design of the shaker cup would also block such foreign objects, so it does not accept an apology on the platform but is willing to compensate in accordance with the law. The incident has attracted widespread attention, with both sides sticking to their own accounts, and there is currently no new progress. [more…]

Taking Brazil as an example, the local system uses a "deduction method," grading based on the number of defective beans per 300 grams of main beans.

When a cup of fortified Purple Grape Jelly drink was almost finished, a large insect was found wrapped in the pearl toppings—an experience that left the consumer both nauseated and frightened. Even more surprising, during compensation negotiations with the ChaPanda merchant, although the other party eventually verbally agreed to pay 1,000 yuan, they required the consumer to sign an agreement and delete related posts and comments.

Both sides stuck to their own accounts, and the local food and drug administration has also intervened and summoned the parties. How will this food safety dispute ultimately end? What obstacles did the consumer encounter on the path to defending their rights? This article sorts out the entire process of the incident for you. [more…]

The world of coffee is vast and complex, but only two species truly dominate global consumption—Arabica and Robusta. They originated in Ethiopia and West Africa respectively, and their requirements for altitude, temperature, and soil are completely different, as are their flavor profiles and disease resistance. Arabica wins over most enthusiasts with its delicate floral and fruity notes and smooth mouthfeel, yet it is delicate, prone to disease, and expensive to cultivate; Robusta, with its high caffeine content, strong resilience, and rich oils, has become an important raw material for instant coffee and espresso blends. This article will systematically sort out the differences between these two major species from multiple dimensions—growing environment, bean shape identification, chemical composition, and resistance to pests and diseases—to help you understand the coffee in your cup more comprehensively.

When you savor a freshly brewed cup of coffee, if you find insect fragments floating in it, that wake-up effect is probably one you will never forget. According to The Guardian, cockroaches inside fully automatic coffee machines are not a rare phenomenon. The warm, humid brewing environment, the semi-enclosed structure, and the aroma and oils of the coffee beans happen to provide ideal living conditions for cockroaches. Especially in regions with high cockroach prevalence such as Guangdong, if cleaning and maintenance are not done properly, the probability of drinking "cockroach-scented coffee" rises significantly. Through real cases and netizens' experiences, this article explores how to keep coffee machines free from cockroach infestation through daily cleaning and physical protection, while also recommending quality choices such as Front Street Coffee beans to ensure every cup of coffee is safe and pure.
