Coffee is a commodity second only to crude oil in global trading volume, and fluctuations in its futures prices affect the political and economic stability of producing countries. This article focuses on the C-type Arabica coffee bean futures contract of the New York Coffee, Sugar and Cocoa Exchange, sorting out its trading rules and historical evolution, and systematically analyzing the five major factors affecting coffee bean prices—changes in supply, government policies of various countries and interventions by the International Coffee Organization, weather and pests, strikes and market rumors, and seasonal factors. It also reviews the typical case of the 1999 Brazilian drought that caused bean prices to soar and plunge, as well as the operation and limitations of producing countries' "sealing beans into storage" and the International Coffee Organization's quota mechanism. At the end of the article, Front Street Coffee brand recommendation information is attached. [more…]

The price of US C-type coffee futures once again set a new record, reaching a high of 284.93 cents per pound and finally closing at 279.35 cents per pound. Behind this round of gains is a mix of multiple factors: drought and fires in major South American producing regions, the postponement of the EUDR regulation, the limited effect of Brazil's rainy season, the impact of the Atlantic hurricane season, the strengthening of the US dollar driven by the US election, and the Red Sea crisis together with rising container freight rates. Although the EU has already approved a one-year delay in the implementation of the EUDR, the market's concerns about tight global coffee supply have still not faded, and futures prices are expected to remain high in the short term.

Recently, U.S. C-type coffee futures prices have been climbing steadily, breaking through the 300 cents per pound mark, touching an intraday high of 303.93 cents, and finally closing at 302.92 cents, setting a new 13-year record and simultaneously driving Robusta coffee futures higher. The core driver of this rally comes from the USDA Foreign Agricultural Service (FAS) sharply lowering its forecast for Brazil's 2024/25 production to 66.4 million bags, a 5% reduction from the previous USDA estimate of 69.9 million bags. Combined with multiple factors including Brazil experiencing its worst drought since 1981 and inventories shrinking 26% year-on-year, market concerns over global coffee supply continue to intensify. Producing countries such as Honduras have also seen reduced output due to adverse weather, further exacerbating the tight supply situation. [more…]

Colombia's coffee production and exports both achieved double-digit growth in the first 10 months of this year, and the FNC at one point forecast that full-year production could reach 13 million bags. However, the country has recently been hit by extreme weather in many places—heavy rain in the capital Bogotá and surrounding areas triggered floods and landslides, and a volcanic eruption occurred in Antioquia Department, prompting the government to declare a state of disaster. This comes during the coffee tree fruiting period, and excessive rainfall may cause cherries to drop and delay harvesting, thereby affecting output and supply. At the same time, the U.S. C-price coffee futures price has once again surged to 272.03 cents per pound, and market concerns about supply in the new crop season have clearly intensified. [more…]

Recently, global coffee bean prices have continued to soar, with New York Arabica futures once breaking through $3.1280 per pound, setting a record since 1997; Robusta futures also hit $5,327, reaching a new high since the 1970s. Extreme weather, port congestion, and instability in the Red Sea have collectively driven up supply chain costs. Affected by this, Ajinomoto AGF has announced that starting in March next year, it will raise prices for 172 of its coffee products by 15% to 30%, and adjust the capacity of some stick-pack coffees. Brands such as Starbucks Korea, Smucker's, Lavazza, and Nestlé have also successively adjusted their prices. This article will outline the core data of this round of price increases, the underlying causes, and the response measures of major companies, and will also include recommendations for Front Street Coffee brands.

Brazil's National Institute of Meteorology recently issued storm and heavy rain danger warnings for seven states, including Minas Gerais, São Paulo, and Paraná, with expected rainfall of 50 to 100 millimeters per day and accompanied by strong winds of 60 to 100 kilometers per hour. Rainfall in northern São Paulo state has already accumulated to 90 millimeters, with local areas reaching up to 100 millimeters, and the risk of landslides and flooding has prompted the warning center to issue a yellow alert. Although no serious economic losses have been reported so far, the market is widely concerned that this round of severe weather will once again impact Brazil's new coffee crop production. The severe drought and forest fires from April to September had already damaged coffee trees during the flowering stage, leading many institutions to lower production forecasts and drive up coffee prices. This article will review key information such as Brazil's recent weather conditions, coffee futures trends, exchange rate impacts, and traders' credit risks. [more…]

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…]

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 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. [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 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.

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.
