Green coffee beans are the starting point that determines the flavor of a cup of coffee. From color and luster to moisture content, every detail reveals the quality code of green beans; the terms "new crop," "current crop," "old crop," and "aged crop," named by harvest year, record how time shapes flavor. During transoceanic shipping, temperature and packaging methods also influence the fate of green beans—low-temperature containers, temperature-controlled storage, and vacuum aluminum foil bags are all effective means of extending good flavor. The ultimate preservation challenge points to a simple yet expensive answer: vacuum packaging followed by freezing. This article systematically organizes the complete knowledge of green beans from identification to storage, and includes practical advice from Front Street Coffee, taking you deeper into understanding this green seed.

The 2021 new-crop Huakui 5.0 coffee beans have arrived at the port. Front Street Coffee immediately carried out roasting and cupping, and specifically conducted a comparison with its own beloved small-bean Huakui coffee beans. This article will guide you through the evolution of the Huakui series from the 2017 TOH champion beans to Huakui 5.0, and explain why small-bean Huakui stands independently outside the X.0 series. Then, through a visual comparison of green beans and roasted beans, differences in cupping flavors, and performance under a unified pour-over recipe, it will present in detail the characteristics of the two beans: small-bean Huakui is closer to the rich strawberry-cream profile of the classic 2017 Huakui, while Huakui 5.0 shows brighter berry acidity and floral notes. Whether you are a Huakui enthusiast or are currently selecting new-crop beans, this review can provide practical reference. [more…]

Green coffee beans are classified into several types based on their degree of freshness: new crop, past crop, old crop, and aged beans. The criteria for determining these categories are not as simple as just looking at the harvest year. Since most specialty coffee beans in China rely on imports, the process from harvesting and processing to transportation often takes several months, so the understanding of what constitutes a "new crop season" cannot be conflated with everyday timelines. Changes in moisture content are the key indicator for distinguishing these beans, and aged beans are a special product deliberately stored for an extended period, fundamentally different from ordinary old crop beans. In this article, Front Street Coffee will systematically sort out the definitions and differences of these types of green beans to help everyone clarify common misconceptions. [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.

In the vast world of specialty coffee, the variables that influence flavor go far beyond origin and processing method. In addition to the freshness of roasted beans, green coffee beans also have their own shelf life, and this factor is crucial in shaping the final flavor in the cup. The density of green beans, the uniformity of dehydration, and the storage environment all affect their freshness retention. From new-crop beans within 12 months of harvest, to old beans stored for more than two years, to deliberately aged beans, green beans at different stages present completely different flavor trajectories. Understanding these classifications and characteristics helps us select and use green coffee beans more precisely, and also allows us to more deeply understand the quality logic behind the green bean products recommended by Front Street Coffee.

Coffee beans, like fruit, are seasonal. Beans from the same mountain—fresh new crop just after harvest versus old beans that have sat for most of a year—can differ by a noticeable margin in the intensity of their floral and fruity aromas. When buying beans in the floral-fruity direction, besides checking the roast date, harvest season information is equally worth noting. Floral-fruity notes are among the faster-fading types of flavor, and freshness plays a [more…]

Brazil, the world's largest coffee producer, has suffered consecutive droughts and frosts, with its 2022/23 harvest falling far short of expectations. Certified coffee inventories on the ICE exchange have continued to decline, keeping coffee futures prices elevated. To ease the inventory crunch, ICE plans to re-grade and re-certify a batch of Brazilian Arabica old-crop beans that have been in storage for nearly two years and put them into trading. Although this move is not a violation of the rules, it has sparked concerns among traders about coffee quality and the mixing of old and new beans. This article will review the background of Brazil's reduced output, the logic behind futures price fluctuations, and the possible chain reactions that re-certifying old-crop beans may bring to the market. [more…]

Does SOE (Single Origin Espresso) equal specialty coffee, and does it equal great taste? The answer is no. As a crop, coffee's flavor fluctuates year by year with the terroir and climate, and the choice of extraction method also brings noticeable differences. Front Street Coffee conducted a comparative experiment using Yellow Bourbon from Queen's Farm in Brazil's Mogiana region, grown at an altitude of 1,400 to 1,950 meters, comparing pour-over and espresso: the pour-over version showed the fresh sweetness of sugarcane juice, with notes of black tea and nutty chocolate, while the SOE version revealed astringency like peanut skin and a thin body. This shows that not all single-origin beans are suitable for espresso; and the nutty, caramel character of Brazilian beans is precisely the ideal base note for espresso blends. At the end of the article, an interpretation of the recipes for Front Street's three espresso blends is attached. [more…]

The world of coffee beans is far more complex than that smudge of amber in your cup. From the small white jasmine-like flowers on the branch to the green raw beans in the processing plant, every coffee bean has undergone layer upon layer of selection by climate, altitude, variety, and processing method. There are about sixty coffee-producing countries worldwide, each grading coffee according to whether it is washed, whether the bean shape is flat or round, bean size, cultivation altitude, defect rate, and even taste tests. The two major varieties, Arabica and Robusta, each hold their own in terms of yield and flavor, while new crop, one-year-old, and multi-year-old beans each have their own character. Understanding these specifications and grading standards not only helps enthusiasts decipher the terminology on packaging, but also understand why beans from the same origin can present such a kaleidoscope of flavors. This article will start from basic common knowledge and systematically sort out the grading logic and refining process of coffee beans. [more…]

Intercontinental Exchange's certified arabica green coffee inventory has plummeted to a 24-year low, totaling just 368,000 bags. More alarmingly, nearly one-third of these beans have been sitting in delivery warehouses for over a year, becoming stale coffee. This situation stems from spot prices exceeding futures prices, prompting roasters to buy directly from exchange stocks, while congestion at Brazilian ports makes replenishment with new beans a distant prospect. The combination of low inventory and the stale bean problem, compounded by global economic and financial uncertainty, has led the market to widely expect green coffee prices to remain highly volatile in the medium term.

Yemen is a name impossible to bypass in coffee history—it has been growing coffee in the most primitive way since the sixth century and remains the only fully sun-dried producing country in the world today. The mocha coffee produced here once captivated seventeenth-century Europeans and became the original meaning of the word "mocha." This article takes you into Yemen's coffee world: from the rise and fall of the port of Mocha, to the flavor differences among classic producing regions such as Mattari, Sanani, and Ismaili; from the agricultural predicament under the double assault of khat and drought, to farmers turning berries on the rooftops of stone houses in the ancient sun-drying method. We will also share Front Street Coffee's roasting curve and brewing parameters for the V60, cake cup, and KALITA three-hole dripper to help you fully understand this complex and wild coffee. [more…]

The latest report from the United States Department of Agriculture shows that Vietnam's coffee production for the 2024/25 season is expected to reach 29 million bags, a slight adjustment from earlier forecasts, but rising coffee prices are encouraging farmers to invest more. Although drought and high temperatures have hit production, measures such as irrigation and intercropping have somewhat eased the pressure of reduced output. At the same time, the planting structure in the Central Highlands is quietly changing, with high-return crops such as durian and passion fruit diverting some coffee acreage. On the export front, Vietnam's coffee exports in the first half of the 2023/24 fiscal year fell 7% year on year, while domestic purchase prices remain persistently high, making traders cautious about signing contracts. The market is skeptical of official production data, and La Niña may become the biggest variable going forward; the new season's harvest will not be known until October. [more…]
