The international Fairtrade organization recently published revised coffee certification standards, aiming to meet or even exceed the various requirements of the EU Deforestation Regulation (EUDR). The new rules will cover all Fairtrade-certified coffee, not limited to products exported to the EU, and strengthen monitoring and reporting obligations for producer organizations and traders. The standard is expected to take effect in 2026, involving approximately 600 cooperatives, 870,000 coffee farmers, and 1.1 million hectares of cultivated land. To implement deforestation monitoring, Fairtrade has commissioned the Dutch company Satelligence to provide satellite data services. Meanwhile, the EUDR will take effect for large European companies between the end of 2024 and early 2025, and the coffee industry is actively adjusting to comply with this regulation. [more…]

The core difference between organic tea and conventional tea lies in whether it has been certified by an authoritative body. EU organic regulations prohibit genetic modification and synthetic inputs, and require animals to be raised in ways that suit their species characteristics, and are regarded as the strictest threshold in the tea industry. Certifications such as Switzerland's IMO, France's Ecocert, the US USDA, Japan's JAS, India's, Canada's, China's, Australia's, and Germany's Naturland each have different emphases, with significant differences in scope of application and difficulty of obtaining them. Rainforest Alliance, UTZ, FDA, and HACCP provide supplementary assurances from the perspectives of sustainable agriculture and food safety. This article systematically sorts out the rules, authority, and market applicability of major certifications, helping coffee and tea lovers accurately identify the true meaning behind labels when making purchases.

Starbucks has announced it will not renew its contract with Fairtrade, meaning coffee sold in its global stores will no longer carry the Fairtrade certification label. This decision has raised questions about its commitment to ethical sourcing. Starbucks says it will instead rely on the C.A.F.E. Practices standard, developed jointly with Conservation International and independently audited by the third-party organization SCS Global Services. However, many groups worry that without Fairtrade's independent oversight, the C.A.F.E. standard may not truly safeguard coffee farmers' rights on core issues such as minimum purchase prices and sourcing from smallholder cooperatives. This article reviews the history of Starbucks' partnership with Fairtrade, the origins and controversies of C.A.F.E. Practices, and Starbucks' past reversals on its ethical sourcing stance, offering coffee lovers a full picture of this event. [more…]

You often hear the "Golden Cup Standard" mentioned in coffee circles—what exactly does it mean? Simply put, it's an extraction reference range derived by Dr. Lockhart in the last century through extensive sampling surveys—when coffee's extraction yield and concentration fall within a specific range, most people find it tastes good. After subsequent research revisions, the optimal extraction yield was ultimately determined to be 18%~22%, and concentration 1.15%~1.35%. However, Front Street would like to remind everyone that the Golden Cup Standard is only a reference benchmark for beginners, not the sole criterion for whether coffee tastes good. This article will break down in detail the origins of the Golden Cup Standard, the meaning of extraction yield and concentration, and why coffee outside this range isn't necessarily bad—helping you understand the extraction logic of pour-over coffee more flexibly. [more…]

When buying coffee beans, have you ever been baffled by combinations of letters like AA, G1, SHB, and PB?

The National Health Commission recently solicited public comments on 19 national food safety standards, among which the "Determination of Acrylamide in Foods" includes coffee within its testing scope for the first time, responding to the social debate sparked by the detection of acrylamide in freshly made and sold coffee. At the end of 2023, a report by the Fujian Provincial Consumer Council brought acrylamide in coffee into the spotlight; experts pointed out that this substance is a byproduct of high-temperature processing rather than an artificial additive, and that its content in coffee is extremely low, so there is no need for excessive concern about daily consumption. This revision of the national standard aims to improve the testing system, drive process improvements in the industry, and safeguard consumer rights. [more…]

When purchasing single-origin coffee beans, labels such as G1, AA, and SHB often appear on the packaging. What exactly do these letters and numbers represent? They are actually coffee bean grade symbols established by each origin based on its own conditions. Due to differences in growing environments and varieties, the grading criteria of different countries vary—some look at the number of defective beans, some at green bean size, and others at hardness or altitude. In this article, Front Street Coffee will sort out the grading standards of major producing regions such as Ethiopia, Kenya, Indonesia, Central and South America, and Brazil, helping coffee lovers understand the meaning behind these grades so they can more accurately select high-quality coffee beans that suit their own taste.

Recently, Luckin Coffee halted the viral social media ordering hack known as "all ice, no water, swap to dome lid," sparking heated discussion among consumers. This drinking method, which replaces still water with ice cubes and swaps the flat lid for a dome lid, makes the beverage richer in flavor and more photogenic, and was once imitated by many netizens. However, because this operation falls outside standardized procedures and causes confusion in store inventory between flat lids and dome lids, the company has issued a notice prohibiting stores from continuing to make it. Some consumers believe the brand should adapt its products to meet demand, while others understand the necessity for chain brands to maintain standardized operations. This debate over the balance between personalized customization and store management is worth the attention of coffee enthusiasts. [more…]

When you get an unfamiliar single-origin coffee bean, how do you accurately judge its flavor performance? Cupping is the industry-standard method. Front Street Coffee conducts cupping on every coffee bean it acquires, whether or not it goes on the shelves. This article uses the SCA cupping system as its benchmark and provides a detailed introduction to the equipment and parameters required for cupping, including sample bean processing, grind size calibration, coffee-to-water ratio, water quality and temperature requirements, as well as the operating procedures for dry aroma, wet aroma, breaking the crust, and skimming. After cupping is completed, the pour-over grind size and brewing water temperature must also be determined according to the roast level. Light-roast and medium-roast coffee beans each have different standards for sieve pass-through rate and water temperature selection. [more…]

Recently, a complaint about Manner's coffee grinding service sparked heated discussion on social media. A customer reported that after buying coffee beans at a store and asking the staff to grind them, they found that their semi-automatic espresso machine at home could not extract espresso properly, and suspected the grind was too fine. When the customer asked whether Manner had a unified grinding standard for its grinding service, neither the online customer service nor the store staff could give a clear answer. This incident brings up an oft-repeated topic in the coffee community: is there really such a thing as a standard grind size for coffee powder used in semi-automatic espresso machines? Multiple industry practitioners and seasoned enthusiasts have offered their views, and the boundaries of chain brands' grinding services have once again drawn attention. [more…]

Coffee enthusiasts often ask Front Street: why are coffee bean grade labels so varied—some are marked AA, some G1, and others SHB? These letters seem to have no connection to one another, so how exactly can one judge which grade is superior? In fact, coffee bean grading systems are not uniform across producing regions worldwide, and the criteria they are based on also emphasize different things. This means that it is very difficult to make cross-country horizontal comparisons based on green bean grade alone. This article will systematically sort out the basic logic of coffee bean grading in various countries, and focus on introducing the grading standards of two major African producing regions, Ethiopia and Kenya, to help readers understand the meaning behind these letters and how green bean buyers refer to this grade information when purchasing.

Common labels on coffee bean packaging such as light roast, medium roast, and cinnamon roast often confuse beginners. The roast level directly determines the direction of coffee flavor, and historically different countries and regions have had their own schools of thought for defining roast levels, lacking a unified standard. The Specialty Coffee Association of America, together with Agtron, used infrared caramelization measurement values as the basis to divide roast levels from light to dark into eight grades, which has become an important industry reference. In this article, Front Street will systematically introduce the Agtron color values, drop times, and flavor characteristics of each roast level, and share how to judge the roast level through flavor descriptions, as well as the grinding degree and water temperature parameters that should be used for different roast levels.

Since McDonald's coffee brand McCafé announced increased investment in the Chinese market, its number of stores has surpassed 3,200. Its "store-within-a-store" model is equipped with semi-automatic espresso machines and dedicated baristas, focusing on a specialty coffee approach. However, recently a netizen posted pointing out that baristas at some McCafé locations operate in a highly non-standard manner: dosing the portafilter in advance, not weighing the dose, not tamping, not cleaning the steam wand, and repeatedly extracting with wet spent grounds left in the basket. Although the prices are not low, the quality of the output has raised consumer doubts. At the same time, some netizens claiming to be McCafé baristas responded that the brand has unified standards, and isolated incidents should not represent the whole. This controversy reflects the quality control and training challenges McCafé faces amid rapid expansion, and is worth the attention of coffee enthusiasts. [more…]
