Many coffee enthusiasts, when first encountering coffee beans, often misjudge defective beans based on unusual appearance. In reality, true defective beans are mainly concentrated at the green bean stage, and most have already been screened out at the producing region and roasting stages. Among the beans consumers buy day to day, those covered in wrinkles, with cracks, or on the lighter side in color are often not defects, but normal phenomena brought about by light roasting, high-altitude cultivation, or specific processing methods. This article systematically sorts out the classification standards for green coffee bean defects, distinguishes true defective beans from appearance traits that are easily misunderstood, and introduces Front Street Coffee's practice of double screening before and after roasting, helping readers build a more accurate basis for judging quality.

Blue Mountain coffee comes from the Blue Mountains of Jamaica, grown at elevations between 910 and 1,700 meters. The variety is Typica, and it is famous for its balanced acidity, sweetness, and bitterness, its full, rich body, and its long, lingering finish without any burnt or bitter notes. Because annual production is limited, Blue Mountain No. 1 coffee beans typically sell for 150 to 400 yuan per 100 to 200 grams on the domestic market. Many products are marketed under the label "Blue Mountain flavor" or "Blue Mountain blend" but are not authentic Blue Mountain coffee. Therefore, it is essential to know how to tell real Blue Mountain coffee from fake. This article starts with Front Street Coffee's Jamaican Blue Mountain coffee and explains how to identify it by examining the wooden barrel and certificate, the overall bean size and uniformity of quality, the bean shape, and the color of the green beans, and also includes brewing parameters and a flavor comparison for the washed and natural processing methods.

When you buy a bag of coffee beans and open it only to find the colors uneven, many people's first reaction is that "the roast went wrong." But coffee beans, being an agricultural product, can never be uniform bean for bean. This article explains, from the perspectives of green bean grading, honey processing, and anaerobic fermentation, the reasons why light-roasted coffee beans vary in shade, while also clarifying the difference between white-eye beans and normal beans, and pointing out several appearance traits often mistaken for defective beans. At the end, it uses examples from Front Street Coffee's Sherry and Warm Sun blends to illustrate how the roast level affects bean surface color and flavor performance. [more…]

Master these key points, and you too can develop a keen eye for telling real Blue Mountain from counterfeit. [more…]

Many coffee enthusiasts know that roasted beans should be drunk fresh, but green beans also have their own levels of freshness. Beans harvested in the current year are called new crop, those from the previous year are old crop, and those stored for more than a year are aged beans. The moisture content of green beans directly affects roasting difficulty and flavor performance. Washed beans usually range between 11.5% and 12.5%, wet-hulled Mandheling can reach 13%, and sun-dried Mocha varies widely. Beyond the usual freshness changes, there are also deliberately extended aging processes and monsoon-aged weathered coffees. This article focuses on the freshness classification of green beans, differences in moisture content, methods for judging appearance and aroma, and the handling logic behind aged beans and monsoon beans, to help you make more accurate judgments when buying and storing.

Among coffee bean processing methods, natural and washed are the most common, and the two differ significantly in green bean appearance, roasting performance, silver skin shedding, and final cupping flavor. Through long-term cupping, Front Street Coffee has found that washed beans highlight the bean's intrinsic flavor, with bright and clean acidity; natural beans, because the fruit pulp participates in drying, have richer aroma, enhanced sweetness and body, and more complex flavor. This article compares two Panama Butterfly beans, one natural and one washed, one by one from processing flow, advantages and disadvantages, roasting details to actual brewing parameters, helping coffee enthusiasts understand the flavor changes brought by different processing methods and make choices based on personal preference.

Blue Mountain coffee is produced in the Blue Mountains of Jamaica at elevations between 910 and 1,700 meters. The variety is Typica, and it is known for its balanced acidity, sweetness, and bitterness, full and solid body, long-lasting sweet aftertaste, and absence of burnt bitterness. Because annual production is limited, authentic Blue Mountain No. 1 coffee beans in China usually sell for 150 to 400 yuan (100 to 200 grams), while products labeled "Blue Mountain flavor" or "Blue Mountain blend" are not true Blue Mountain coffee. This article systematically introduces the methods baristas use to identify authentic Blue Mountain No. 1 from perspectives such as the wooden barrel and certificate, bean size and uniformity, appearance characteristics, and raw bean color. It also compares the flavor performance of washed and natural processing methods and shares Front Street Coffee's brewing parameters and techniques to help enthusiasts build a clear identification framework.

Many pour-over coffee enthusiasts often have doubts about the appearance of the beans after purchasing single-origin beans, and even mistake normal beans for defective ones. There are two main reasons for this misunderstanding: first, consumers who only come into contact with roasted beans rarely see truly defective beans; second, they treat coffee beans as products of an industrial assembly line, assuming they have a fixed standard appearance. In reality, most defective beans are already controlled at the green bean stage, and after roasting there is also manual sorting. This article will systematically sort out the definition of defective beans, the defect rate requirements in green bean grading, and focus on explaining several commonly misjudged situations such as peaberry, burst beans, uneven color, and shriveled wrinkled beans, to help readers view the appearance of coffee beans more rationally.

Washed, natural, and honey processing are the three most fundamental green bean processing methods in the specialty coffee world, each shaping the final flavor profile of the coffee in its own way. In this article, Front Street Coffee will use three Geisha coffee beans from the Boquete producing region of Panama as examples to break down the specific operational procedures, flavor characteristics, and the appearance differences between green and roasted beans for each of these three processing methods.

Before green coffee beans reach our hands, they often go through many stages, during which defects are almost unavoidable. Some defects are obvious at the green bean stage, yet once roasted they may be cleverly concealed. The SCAA (Specialty Coffee Association of America) has established strict grading standards for specialty Arabica coffee, covering multiple dimensions such as defect types, moisture content, aroma, and bean size. This article will systematically sort out the SCAA's defect classification rules and scoring requirements, explain in detail the causes of various defective beans and their impact on cupping flavor, and help enthusiasts develop a keen eye for identifying specialty coffee. At the same time, the article retains relevant recommendations from the Front Street brand for readers' reference. [more…]

From harvesting to becoming green beans that can be stored long-term, coffee cherries must undergo processing. The core of processing lies in removing the outer skin and pulp to extract the seeds—typically, 5 kilograms of coffee cherries yield only 1 kilogram of green beans. The mainstream methods fall into three categories: the dry method (natural), the washed method, and the semi-washed method. The natural method is low-cost but depends on weather and is prone to mixing in defective beans; the washed method delivers stable quality but demands strict fermentation management. Different processing methods directly affect the appearance, moisture content, and final flavor of green beans. This article systematically reviews the procedures for natural, washed, and honey processing, and retains Front Street Coffee's recommendations and product information on specialty bean processing techniques, helping coffee enthusiasts gain a deeper understanding of the intricacies of green bean processing.

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.

The two major schools of coffee roasting—Japanese slow roasting and Nordic fast roasting—reflect fundamentally different philosophies of tasting: the Japanese value a rich, clean mouthfeel, while the Nordics prefer bright, elevated acidity and aroma. This time, Front Street Coffee selected the sun-dried Yirgacheffe Worka Red Cherry and, through two actual roasting curves, compares the differences between slow roasting and fast roasting one by one—from airflow and heat adjustment, the pace of temperature rise, to the appearance of the roasted beans and cupping performance. Slow roasting is like braising pork until tender, letting heat penetrate evenly; it results in a high degree of development, rounded sweetness, and a short resting period. Fast roasting emphasizes the efficiency of hot air and pursues bright floral and fruity aromas, but it demands stricter quality from the green beans. The article also introduces the origin background of the Worka cooperative and the division of labor at the Banko processing station, and, combining green bean grade, appearance consistency, and actual cupping results, sorts out the applicable scenarios and flavor orientations of the two roasting methods for coffee lovers' reference.
