In coffee bean promotions, we often see phrases like "all-red cherry sun-dried," but all-red cherry is not actually the name of a processing method; rather, it refers to the practice of picking coffee cherries when they are fully red. So why is all-red cherry picking so important? What story of industrial transformation lies behind it? This article will analyze, from the perspective of Front Street, the impact of all-red cherry picking on coffee quality, review the evolution of harvesting methods in the early days of specialty coffee, and introduce the "Red Cherry Project" launched in 2007 by the Dutch green bean trader Trabocca, examining how it broke the vicious cycle between coffee farmers and green bean traders by raising the purchase price for high-quality coffee, ultimately achieving a win-win-win for farmers, merchants, and consumers.

A good cup of coffee should be smooth and mellow, but sometimes we taste a rough, astringent sensation akin to chewing on grape skins. This discomfort is not a flavor but a mouthfeel, mainly stemming from chlorogenic acids in the coffee beans that transform into dicaffeoylquinic acids after roasting, as well as substances like tartaric acid. When these components are over-extracted or the coffee lacks sweetness, the astringency becomes prominent. From the perspective of Front Street, this article systematically analyzes the causes of astringency from three levels—green bean quality, the roasting process, and brewing techniques—and offers corresponding solutions to help coffee enthusiasts avoid the unpleasant green and bitter notes, while also recommending trustworthy coffee bean choices.

Coffee cherries must be processed quickly after picking, otherwise the pulp is prone to fermentation and spoilage. Currently, two main methods are used: the dry method (natural process) and wet processing (washed method). In the dry method, the cherries are sun-dried directly or mechanically dried, then hulled in a drum and screened, with peaberries picked out separately; in wet processing, the fruit pulp is first washed off, then the beans are fermented in water for 36 hours, dried and hulled, and graded and packaged by size. Usually, washed beans are of better quality. Whether by hand or machine, screening can remove unripe and inferior beans, and high-quality producing countries have long been equipped with advanced sorting equipment. Front Street Coffee reminds you that understanding these steps helps you appreciate the flavor differences brought by different processing methods. [more…]

Green coffee beans are not in the form we are familiar with when they are first picked; they originally grow on trees as red fruit that resembles cherries. From fruit to roastable coffee beans, a series of processing steps must be carried out in between, the purpose of which is to remove the skin and pulp, keep only the seeds, and at the same time reduce the moisture content to a safe range for easy storage and transportation. Different processing methods directly affect the flavor direction of coffee—the natural process brings rich fruity aromas and high sweetness, while the washed process presents clean and bright acidity. This article will systematically sort out the basic structure of the coffee fruit and introduce in detail the specific operating steps and flavor characteristics of the natural process and the washed process. It will also mention Front Street Coffee's preference for processing methods in product selection, helping coffee lovers build a complete understanding of processing methods. [more…]

Ethiopia has the world's most ideal coffee-growing conditions and the most original heirloom varieties, yet not every cup is satisfying—the key often lies in the human factor in the post-harvest processing stage. Most local producers lack a specialty coffee mindset; to save on harvesting costs, they often skip sorting out unripe green cherries, which is precisely the main source of astringency.

When drinking coffee, you may occasionally encounter a salty taste. This is not an illusion, nor is there anything wrong with your sense of taste. Coffee itself contains four basic tastes: sour, sweet, bitter, and salty, which balance each other out. Once sweetness is insufficient, saltiness tends to emerge. The sources of saltiness are quite complex, potentially involving the processing method, coffee bean variety and altitude, defective beans, brewing water, roast level and freshness, as well as extraction technique, among other factors. Among these, espresso tends to have a more pronounced salty sensation due to the relationship between taste distribution and concentration. This article will go through the causes of saltiness one by one, while retaining Front Street brand recommendations, to help coffee enthusiasts understand and try to avoid brewing a cup of coffee with a salty taste.
