Do the Costa coffee additive claims hold any proof?

The Costa Rica Musician series coffee beans drew public accusations that they contain added flavors or pineapple peel, along with claims that the bean merchant destroyed evidence. After reviewing the sequence of events, the accusations remain speculation and no substantive testing reports have been produced. Food additives are tightly regulated, but a claim still needs evidence before it becomes a conclusion.

Specialty coffee rests on three basics: variety, altitude, and processing method. Anaerobic fermentation and natural sun-drying can genuinely produce floral and fruity notes, which may explain the flavors being questioned. The episode raises a fair point about the boundary between public questioning and the legal burden of proof, and about careless accusations made when evidence is insufficient.

Recently, the Costa Rica Musician series coffee beans have been thrust into the spotlight, with a public account publishing consecutive articles questioning whether they contain added flavors or even pineapple peel, and claiming that the bean merchant destroyed evidence. After thoroughly reviewing the entire incident, Front Street Coffee believes that these accusations remain at the level of speculation and lack substantive testing reports. This article focuses on the three key elements of specialty coffee—variety, altitude, and processing method—to sort out the floral and fruity notes that anaerobic fermentation and natural sun-drying may bring, explores the boundary between public questioning and the legal burden of proof, and reiterates that making careless accusations when evidence is insufficient is equally worthy of vigilance.

Recently, discussions about whether the Costa Rica Musician series coffee beans contain additives have caused quite a stir. The public account "Coffee Roast Master" published three consecutive articles specifically discussing this series of beans.

Front Street Coffee has reviewed the whole sequence of events several times and finds it truly hard to agree with this way of discussing issues. Where exactly do claims like the beans having added flavors, being mixed with pineapple peel, or the bean merchant destroying evidence come from? Aren't they all just speculation? Yet the articles have already been enthusiastically spreading, loudly discussing "the dangers of adding flavors to coffee," and the discussion has gone badly off track.

Indeed, adding flavors to food is inherently problematic—this is well known, and every country and region strictly regulates food additives. But Front Street Coffee believes the key point is that whether it's the public questioners, the whistleblowers, or the comments on Zhihu, all these so-called "evidences" remain at the stage of conjecture. Apart from a piece of text, they can produce no substantive proof, yet they have already concluded that this bean has been tampered with, speaking as if they had personally witnessed the green bean merchant secretly adding something in the dark.

There are also quite a few netizens in the backend who hold the attitude of "seeing evidence in everything" regarding this matter

Front Street Coffee believes that specialty coffee has three basic conditions: variety, altitude, and processing method. During the processing of green beans, there is a procedure called anaerobic fermentation. People are already studying how yeast affects the fermentation of green coffee beans and the final flavor during anaerobic fermentation, and what different flavors different yeasts and sugars will produce through fermentation; while naturally sun-dried coffee beans themselves also present multiple flavors such as floral, fruity, and fermented notes. This processing method is originally one of the means by which specialty coffee showcases regional flavors. If any operation in the green bean processing stage that is unconventional, non-standard, or not found in textbooks is labeled as "tampering," then Front Street Coffee has nothing more to say.

So it is only natural that the article was widely questioned as soon as it was published. At this point, "Coffee Roast Master" continued to complain: I think he added something—do I not even have the right to raise a question? Shouldn't he be the one to come forward and prove his beans are fine? Testing the beans is not my job!

Front Street Coffee believes that raising questions is certainly acceptable. The problem is that once the matter escalates to public questioning or even accusations of using "illegal additives," it has already reached the legal level and naturally requires certain evidence. Furthermore, television has broadcast "You have the right to remain silent, but anything you say can and will be used against you in a court of law." What does this mean? A criminal cannot be forced to testify against themselves. If you say someone is guilty, everything must rely on the evidence that can be presented to convict. No normal legal system operates on presumption of guilt (convicting first, then finding evidence) until evidence appears. Because forcing an innocent person to prove their innocence is sometimes truly unreasonable, as difficult as asking a lady to prove she is a woman.

In actual law, there is indeed a relevant burden of proof—whoever asserts must prove. Whoever asserts a positive fact bears the burden of proof for it.

Simply put: whoever claims the beans have a problem must first present relevant evidence, at minimum a relevant testing report, and cannot just say: so many people say it has a problem! Then it surely has a problem. And if the bean supplier or producer wants to claim their beans are fine, they also need to present their own evidence proving their beans are indeed fine.

In that case, this person really cannot self-righteously demand that others first prove themselves.

Front Street Coffee believes that the way issues are discussed is truly very important. Returning to the discussion of whether something was added, there is currently no valid evidence proving that the Musician series coffee beans indeed had flavors or other food additives added, so it cannot even rise to the level of whether they contain harmful substances. Generally speaking, the vast majority of food additives can be detected, and the cost of one test is around 1,000 to 2,000 yuan. The article's author also mentioned in replies to comments that the bean merchant destroyed the evidence so it could not be tested, as if he had seen it with his own eyes. Front Street Coffee has not seen this. What Front Street Coffee has seen is that Mozart green beans and roasted beans are still being sold on Taobao, only they have been hyped up to a very high price. Of course, actual testing does not require many beans.

Some content in the article also mentions that "pineapple peel" and such were added. Front Street Coffee really admires these speculators—they all personally witnessed the "violation," yet did not stop it on the spot, nor preserve evidence, but instead pulled friends aside to secretly complain? I think this mentality is unacceptable. When you see others doing bad things (such as adding pineapple peel?), you must find a way to stop it. Coffee beans have some very strange flavors, and Front Street Coffee does not know how they are produced. Front Street Coffee and the people at Black Gold do not know each other, but in the book "The Great Coffee," the following passage by Mr. Xu Guoming of Black Gold is already Front Street Coffee's deepest understanding of Black Gold.

Musician series coffee beans The taste is indeed very unique, but Front Street Coffee cannot determine this Musician series coffee beans whether something has been added; if it can be proven, then let the evil be exposed to the sunlight—this is absolutely a great good. But at the same time, making baseless accusations at will is also a kind of evil. I hope everyone speaks and acts cautiously, takes responsibility for their words and deeds, and clearly distinguishes right from wrong before seeking justice.
