Aged coffee beans are a type of green coffee that, through special storage management, transforms over a long period of time to develop a unique flavor profile—mellow acidity, full body, and a honey-like sweetness.

Sacred Lion coffee beans have attracted considerable attention from coffee enthusiasts in recent years. Which estate do these beans actually come from? And what makes them so special? The answer points to Ethiopia's Hambela estate, specifically lot 121 produced by the single farm Benti Nenqua. The estate belongs to METAD, and after Aman Adinew, who once held a key position at a Fortune 500 company, took over the family business, he introduced corporate management and SCAA quality standards, equipping it with a farm, processing plant, and coffee laboratory. Green bean traders named it "Sacred Lion" and specifically noted the SLD single-layer slow drying process to distinguish it from other natural Ethiopian beans. The cupping profile presents tropical fruit, citrus, stone fruit, strawberry jam, and a blueberry finish.

Aged Mandheling is a special type of coffee that has undergone prolonged resting and maturation, giving it a flavor distinct from regular Mandheling. It originated in the era of long maritime shipping, and today it relies on strict warehousing management at the origin to "create" beans with soft acidity, full body, honey-like sweetness, and complex aged notes.

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.

The 2022 Alishan Estate Coffee Elite Exchange Competition and Green Bean Matchmaking Evaluation was held on May 11. Competing beans were divided into four groups by processing method: washed, natural, honey, and Geisha. Participants had to submit parchment and green beans, which the organizers uniformly roasted, and then 15 CQI-certified Q-Graders conducted sensory evaluations using the SCA cupping form. Only beans scoring 80 or above could participate in the auction. In the auction the next day, the special prize in the natural group, Zouzhuyuan Coffee Beans, started bidding at NT$60,000 and soared all the way to NT$520,000/5kg, won by the Lion Group, setting a new record for Taiwanese coffee bean auctions. Notably, these beans were not of the Geisha variety, yet they fetched a top-tier Geisha price, while the special prize in the Geisha group was only NT$320,000. This article takes you through the ins and outs of this sky-high bidding and analyzes the industrial logic behind the rise of Taiwan's local coffee. [more…]

I've tried quite a few Mandhelings, but aged Mandheling is a special existence that requires time to craft. It draws on the idea of Indian monsoon coffee: the green beans must be quietly aged in a ventilated, cool warehouse environment for 24 months, during which they are regularly turned to prevent mold and insect damage, consuming a great deal of labor. After this treatment, the beans' acidity is greatly reduced, their body is significantly improved, and their sweetness carries a honey aroma, with a flavor profile completely different from fresh beans. This time, Front Street Coffee used Sumatra Typica as the sample, roasting it medium-dark with 550g batch size in a Yangjia 800N roaster, and completed brewing with a KONO dripper at 88°C water temperature, ultimately presenting a cup that interweaves herbs and caramel. This article will fully break down the story behind this unique Mandheling, from the principles of the aged processing method, changes in the appearance of the green beans, details of the roasting curve, to the brewing parameters.

Kopi Luwak, also known as cat poop coffee, is produced in Indonesia and is one of the most expensive coffees in the world. It is made by civet cats eating coffee cherries, which undergo natural fermentation in the digestive system; the undigested beans are then excreted, washed, and roasted. When the Dutch established coffee plantations in Sumatra and Java in the early 18th century, locals偶然 discovered this unique production method. Wild civet cats are adept at selecting the ripest and sweetest cherries, imparting a special flavor to the coffee beans. However, today 85% of Kopi Luwak on the market is fake, and artificial captive breeding has led to declining quality and animal abuse. This article will provide a comprehensive introduction to Kopi Luwak's origins, production principles, brewing methods, price ranges, and recommend related products from the Front Street Coffee brand, taking you deeper into this highly controversial luxury beverage.
