Terra Nera coffee beans are produced in the Quechua region in the southeastern Andes of Peru. Their value is greatly enhanced by the involvement of the palm civet (Uchunari) in processing, and they are recognized as one of the most expensive and rarest coffees in the world. Its annual output is affected by natural conditions and the state of the palm civets, and has sharply dropped from 70 kilograms to about 45 kilograms. It is divided into six grades, with the top Grade 0 being entirely hand-selected. These beans are sold only in limited quantities at Harrods in London, and must be roasted to order after reservation. Grade 0 even comes with English sterling silver decoration and a 24K gold-plated bag, with the name engraved by a silversmith. In terms of flavor, it is 100% Arabica, with notes of bitter cocoa, hazelnut, and dried leather. The mouthfeel shifts from light to buttery and silky, with a rich, mellow finish. Front Street Coffee will also continue to follow developments involving this kind of rare bean. [more…]

The Geisha variety has always been most famous in Panama and Ethiopia, but Geisha grown in Colombia is equally worth paying attention to.

While browsing coffee-related knowledge, many people may have encountered the saying that "coffee beans are divided into male and female." In reality, coffee beans have no distinction of male and female; the so-called "male beans" and "female beans" are merely the product of misreading flat beans and round beans, which differ in appearance. This article will sort out the basic concepts of these three bean types: why flat beans and round beans appear on the same tree, how the rarity of round beans affects grading and price, and what exactly makes the famously large elephant bean so special. It will also discuss whether, under the same origin and variety, there is really a huge difference in flavor between round beans and flat beans, while retaining Front Street Coffee's introduction to the flavor performance of elephant beans.

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.

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…]

Defective beans are generally considered in the specialty coffee world to affect the flavor performance of a cup of coffee. If you have the habit of buying coffee beans and brewing at home, do you need to specifically pick out defective beans before brewing? In fact, green coffee beans undergo grading after processing, and most grading systems include a defect rate indicator. The number of defects in high-grade coffee beans has already been pressed to a very low level. From green bean grading, removal before roasting, to screening after roasting, with layer upon layer of checks, there is basically no need to worry about defective bean issues when buying roasted single-origin coffee beans. However, some coffee beans that look like defects are actually normal phenomena. Front Street Coffee has summarized several common types of situations that are easily misjudged, to help everyone distinguish them accurately. [more…]

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.

There is a popular saying online that coffee beans are divided into male and female, which confuses many enthusiasts. In fact, coffee beans have no gender differences; the so-called "male beans" and "female beans" are simply round beans and flat beans with different shapes. This article will trace the origin of this claim, explain the reasons for the formation of round beans, and analyze their special status in coffee grading and pricing. At the same time, we will also discuss whether there is really a difference in flavor between round beans and flat beans, and why most producing regions do not specifically screen for round beans. By understanding these basic facts, you will be able to view differences in coffee bean shapes more rationally and no longer be misled by marketing talk. [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…]

In coffee circles, there has long been a saying that coffee beans are divided into "male" and "female" beans. Some people call oval beans "male beans" and flat beans "female beans," and use this to drive up the price of round beans. However, the truth is that coffee beans have no gender distinction. The difference between round beans and flat beans comes from whether the ovule was successfully pollinated during fruit development. Round beans are sought after because they are rare, but they show no significant flavor difference from flat beans of the same variety from the same origin. This article will systematically sort out the origin of round beans, their particle size characteristics, the logic of grading and pricing, and the actual attitudes of various producing regions toward round beans, to help you view this special bean shape rationally. [more…]

Coffee enthusiasts who often pick freshly roasted coffee beans at FrontStreet Coffee know that the optimal flavor period for coffee beans is within one month, while for drip bag coffee it is half a month; does this mean that just-roasted coffee beans are at their freshest? This [more…]

Friends who often follow Front Street should know that Front Street focuses on freshly roasted coffee.
