Luckin Coffee recently launched a new product line—the Full-Extraction Series, comprising three milk coffees: Full-Extraction Oat Latte, Full-Extraction Meteorite Latte, and Full-Extraction Latte, recommended by Anthony Douglas, the 2022 WBC World Coffee Champion. The brand claims to use the Café Crema full-extraction process to extract more coffee liquid to enhance concentration, targeting those who prefer strong flavors. However, the first batch of reviews on social platforms has been uniformly negative, with consumers describing the taste as resembling dishwater or burnt herbal medicine soup. What exactly is the concept of full extraction? How does it differ from espresso? Why are consumers not buying it? This article analyzes from the perspectives of extraction principles and market trends. [more…]

In espresso preparation, baristas often require the bean hopper to be kept nearly full, but what principle lies behind this? How do changes in hopper pressure affect the uniformity of coffee grinding, and in turn alter the flavor expression of espresso? Starting from the internal structure of the grinder, this article explains the mechanism by which hopper pressure forms and its impact on extraction, and, combined with comparative experiments by Front Street Coffee, presents the actual differences in espresso between a full hopper and a less-than-full hopper. For home users who do not pull shots continuously, is it also necessary to pay attention to this detail? Read the full article, and you will get a clear answer. [more…]

Tamping the puck flat is a basic consensus in espresso extraction, but how much force should actually be used to tamp it down has long been a point of disagreement among baristas. Some give the tamper a light spin and apply just a little pressure, while others put their whole body weight into compressing the puck as hard as possible. Front Street conducted a comparative experiment using two grind sizes—coarse and fine—tamping with a regular force of 1.5 kg and a full-force press of about 9 kg respectively, to observe changes in extraction time. The results showed that because coffee grounds differ in density, the force needed to reach a compacted state also varies: fine grinds require greater pressure to be tamped to their most compact state, while coarse grinds are already sufficiently compacted at 1.5 kg, and full-force tamping produces extraction results almost identical to regular force. This article will present the full experimental process and conclusions to help coffee lovers understand the relationship between tamping force and grind fineness. [more…]

Tamping is a step in espresso making that seems simple but is full of subtle knowledge. Baristas have different understandings of tamping: some believe a light press to level the grounds is enough, while others are used to pressing down with full force. So, does tamping pressure actually affect the extraction result? Front Street Coffee conducted two sets of comparative experiments, using coarse-ground and fine-ground coffee powder respectively, and observed the changes in extraction time after tamping with different pressures. The experiments revealed a key rule: the effect of tamping pressure on extraction is not fixed, but is closely related to the coarseness of the coffee grounds. This article will take you deeper into the true role of tamping, the differences in understanding among different schools of thought, and how to flexibly adjust tamping pressure according to grind size, so that every cup of espresso is more stable and outstanding.

Deep-roasted coffee beans should typically present a full, smooth, and rich mouthfeel, yet many enthusiasts find the flavor rather thin when brewing with pour-over methods. Front Street Coffee, drawing on common issues, points out that the problem often lies in the type of dripper, the coffee-to-water ratio, the extraction time, and the pouring technique. If you want to brew a heavy-bodied cup, it is recommended to choose a Kono dripper or a Kalita wedge-shaped dripper, which rely primarily on immersion extraction, keep the coffee-to-water ratio between 1:13 and 1:15, and maintain an extraction time of around 2 minutes; when pouring, use small circular motions and keep the water level from exceeding the coffee bed, which can also noticeably enhance the body. This article analyzes these key parameters one by one to help you achieve a more solid mouthfeel when brewing deep-roasted beans such as Blue Mountain and Mandheling. [more…]
