In recent years, an increasing number of specialty green coffee beans processed with special processing methods have appeared on the specialty coffee market. Is this really something to be happy about? Front Street Coffee believes that special processing methods were originally intended to give the flavor of coffee beans from a certain producing region more distinctiveness. However, as their use has continued to expand, some processing methods today seem to be more about masking the defects of the coffee beans themselves and then selling them at a high price. In fact, all special processing methods have evolved around the three traditional methods: washed, natural, and honey. This article will systematically sort out the most common types of special processing methods on the market, including anaerobic fermentation, barrel fermentation, and red wine processing, and, combined with Front Street Coffee's cupping experience and specific products, analyze their processing procedures and flavor characteristics.

What do the labels commonly seen on coffee packaging—natural, washed, honey—actually mean? This article focuses on the natural process and its innovative offshoot, the red wine–style natural process. Starting from the structure of the coffee fruit, it breaks down in detail the steps of the natural method, its cost advantages, and defect risks, and further explains how the red wine process uses controlled fermentation to enhance sweetness, cleanliness, and complex acidity. The article also draws on specific products such as Front Street Red Cherry, Huakui, ALO, and the Panama Hartmann Estate to show how traditional natural and red wine natural coffees actually perform in aroma and mouthfeel, helping coffee lovers understand more clearly how processing methods influence the flavors in the cup.

In recent years, red wine processing has attracted much attention in the specialty coffee world. Drawing on the fermentation control concepts used in winemaking, it intervenes in pH, temperature, humidity, and microbial conditions to give coffee beans a rich acidity and complex aroma reminiscent of red wine. This article will start with the flavor differences between lactic acid fermentation and acetic acid fermentation, outline the specific operational process of red wine processing, and combine it with the origin information of Front Street Colombia Red Wine Process—the eastern slopes of the Andes in Cundinamarca Department, a growing altitude of 1,800 to 2,000 meters, and the anaerobic fermentation practice of Remi Sultan in sealed metal containers—to provide coffee lovers with a complete set of flavor descriptions and grinding setting references.

The red wine process is a method of processing green coffee beans that draws on winemaking concepts, and currently only a few estates in Colombia have successfully commercialized it. Depending on the fermentation environment, it can be divided into three types: acetic acid fermentation, lactic acid fermentation, and mixed fermentation, each presenting distinctly different flavor characteristics. At the same time, the washed method and the semi-washed method (honey process) remain the most mainstream processing methods in the specialty coffee field, and many of Front Street Coffee's representative beans use these techniques. This article will systematically sort out the classification and flavor performance of the red wine process, and compare the processing flows of washed and semi-washed methods, to help coffee enthusiasts more clearly understand the impact of processing methods on the flavors in the cup.

Ethiopia, as the birthplace of Arabica coffee, typically relies on washed or natural processing, making honey processing already rare, while red wine processing is even more of a rarity. The Ethiopia·Deli that Front Street Coffee is sharing this time comes from the Guji region, uses red wine processing (i.e., carbonic maceration), features the local native variety Heirloom, is grown at an altitude of 2000-2200 meters, and is graded G1. This article will guide you through the terroir conditions of the Guji region, the principles and characteristics of red wine processing, and include Front Street Coffee's roasting curve and pour-over recommendations to help you gain a comprehensive understanding of this uniquely flavored coffee.

The wine process, also known as the controlled fermentation method or lactic/acetic fermentation method, was developed by a team led by Felipe Sardi of the United States, whose members include biological scientists and ecologists. Strict standards are enforced during picking: underripe cherries below 2%, defective beans below 3%, and floating beans below 5%. This processing method is divided into two paths: aerobic acetic fermentation and anaerobic lactic fermentation. The former has a cleaner and brighter acidity with citric notes; the latter has a rounder mouthfeel and higher body, but slightly lower cleanliness, displaying malic and tartaric acid characteristics. Batch consistency is achieved through pH monitoring. Wine-processed green beans are darker in color, with silver skin appearing wine-red or brownish-red. Front Street Coffee's Panama Hartmann is a representative example, and this article shares its pour-over parameters and flavor performance. [more…]

We also share Front Street's roasting curve, cupping results, and V60 staged pouring parameters to help you understand what makes this bean so unique. [more…]

In coffee flavor descriptions, wine-inspired terms such as red wine, champagne, and whiskey are common, and many consumers wonder: does coffee contain alcohol? Can you drive after drinking it? In fact, these wine-like aromas come from the aromatic molecules in the coffee itself, not from added alcohol. From the perspective of Front Street, this article systematically sorts out the sources of wine-like aromas in coffee, focusing on the effects of processing methods, roast level, and extraction method on the expression of wine-like aromas, and explains why cold brew, ice drip, and iced brewed coffee can present fruity wine flavors. At the same time, readers are reminded to distinguish between black coffee and specialty coffee drinks, to avoid the risk of drunk driving caused by alcohol contained in specialty coffee drinks.

Carbonic maceration processing, also known as the CM process, falls under the category of anaerobic processing. In 2015, Sasa won the World Barista Championship with this type of coffee bean, bringing this innovative technique into the public eye. The method was inspired by red wine making, achieving fermentation by injecting carbon dioxide into a sealed stainless steel tank. The CM process has two versions, natural and washed, differing in the material fermented inside the tank. This article provides a detailed analysis of its flavor characteristics, processing flow, and key control parameters, along with related product recommendations from Front Street Coffee. [more…]

Front Street Coffee was recently asked: Does the red wine process mean soaking coffee beans in red wine? Will the finished product contain alcohol? In fact, the red wine process simply borrows the idea of wine fermentation to process coffee cherries; it does not involve soaking in red wine. During fermentation with the mucilage, a trace amount of alcohol is indeed produced, but after high-temperature roasting it has long since evaporated completely, so there is no need to worry about residue. In this article, Front Street Coffee takes the red wine process coffee beans from Panama's Hartmann Estate as an example, from the estate's background, the characteristics of the Catuai variety, and the operational details of controlled fermentation, to the roasting curve, cupping report, and V60 brewing parameters, to fully break down how this coffee with vinous notes is born.

Central and South America are the core regions of the global specialty coffee world. Central American coffees are mostly grown in high mountain areas at elevations of 1,600 to 1,700 meters, where the significant temperature difference between day and night lengthens the fruit ripening cycle, which in turn increases bean density, and the cup profile often shows soft acidity, good cleanliness, and medium body. Through cupping, Front Street Coffee has found that the flavor differences among producing countries are quite distinct. This article will examine one by one the coffee characteristics of five well-known producing countries: Panama, Colombia, Costa Rica, Brazil, and Honduras, covering their main producing regions, elevation conditions, representative estates, and cupping performance, and will also include information on several representative coffee beans currently sold by Front Street Coffee along with brewing flavor descriptions, providing coffee lovers with a complete reference on regional flavors.
