What kind of flavor performance would using warm milk instead of cold water to extract coffee bring? Front Street Coffee conducted a comparative experiment with three beans of different roast levels and found that the medium-roast bean, when soaked in warm milk, had both fruity aromas and chocolate notes, and its mouthfeel was the most appealing. But the experiment also revealed the problem that a milk temperature of 40°C combined with a granulated sugar grind size and a 3-hour soak easily led to over-extraction. For this reason, Front Street adjusted the plan, shortening the time to 1.5 hours and switching to Ethiopian Santa Vini beans, obtaining a smooth milk coffee interwoven with honey, pineapple, and cream biscuit notes. This article fully records the experimental process and tasting results, providing a reference for enthusiasts who want to try milk-extracted coffee. [more…]

Espresso extraction involves numerous variables, and portafilter temperature is often overlooked. Front Street Coffee designed a comparative experiment to address the question of "whether the hot or cold brew head affects tamping force": keeping dose and yield fixed while only changing the portafilter temperature, recording time, concentration, flavor, and milk-coffee performance. The experiment used Front Street Sunflower Warm Sun Blend, and the results showed that although temperature did not significantly change the extraction yield, it clearly steered the flavor direction—a preheated portafilter made the full-bodied feel and winey notes more prominent, while a chilled portafilter amplified the fruity acidity and light texture. This article will present the complete experimental data and tasting conclusions, and answer whether tamping force needs to be adjusted with temperature, as well as how to decide on a portafilter preheating strategy based on the coffee bean roast level.

Sun-dried and washed are the two most common methods of green coffee processing, but do you truly understand their specific effects on flavor? Front Street Coffee has previously introduced the principles of these two processing methods separately, and this article goes a step further by using the same Yirgacheffe as a sample to make an intuitive comparison across dimensions such as dry aroma, mouthfeel, cupping, and pour-over parameters. Sun-dried processing tends to bring a fuller sweetness and tropical fruit notes, while washed processing is known for its clean, bright acidity and floral aroma. The article also lists in detail specific pour-over recommendations for both processing methods of Yirgacheffe, helping you reproduce the ideal flavor at home. Whether you are a beginner pour-over enthusiast or a seasoned player choosing beans, this comparison can provide you with a clear reference. [more…]

The difference between a hot americano and an iced americano ultimately comes down to whether the espresso is combined with hot water or iced water. This seemingly simple combination actually involves a lot of nuance—water temperature, the coffee-to-water ratio, and the timing of tasting all influence the final flavor of an americano. This time, Front Street Coffee brewed hot americanos with four different water temperatures—55°C, 65°C, 75°C, and 90°C—and compared them at three points in time: just after brewing, 5 minutes later, and 20 minutes later. Using measured data, we’ll tell you which temperature is best for serving a hot americano for dine-in, and reveal the complete pattern of how coffee flavor changes over time at different water temperatures.

The article also introduces the changes in tea flavor brought about by reduced rainfall in 2018, as well as reservation information for two distinctive oolong teas from Alishan and Dongding Mountain. For those who love exploring the depth of oolong tea flavor, this is a guide to craftsmanship and tasting worth reading carefully. [more…]

There are many different pour-over brewing techniques, and staged pouring is widely recognized as an effective way to enhance a coffee's complexity. But have you ever wondered exactly which flavor compounds each pour extracts from the coffee? Front Street Coffee conducted a comparative experiment, selecting a light-roasted fruit-acid Kenya Kirinyaga AA and a medium-roasted nutty Yunnan natural Typica, using a four-pour method to collect the coffee liquid from each stage separately. After tasting each one, they revealed which flavor components are respectively responsible during blooming, the middle stage, and the final stage. Building on this, this article further summarizes how to apply these extraction patterns to actual brewing—how to adjust parameters to highlight sweetness, and how to distribute water to achieve a juicy mouthfeel—offering concrete, actionable ideas for each.

Pour-over and siphon are two common specialty coffee brewing methods. Although both can express a coffee's terroir, their different extraction principles and filtration media mean the final cup emphasizes different aspects of taste. This article systematically compares siphon and pour-over brewers, from their historical origins and brewing principles to operating parameters and actual tasting. Pour-over uses paper filtration, giving a clean flavor with rich layers; siphon relies mainly on immersion and flannel filtration, producing a full-bodied, balanced taste. The article also uses Front Street Yemen Mocha brewed both ways, with specific parameters and flavor descriptions, to help coffee lovers more intuitively understand the differences between the two and find a brewing style that suits them.

In the Yunnan coffee market, the Catimor variety accounts for the vast majority. To mask some of Catimor's inherent flaws, many producers turn to special processing methods to reshape the flavor, but Front Street Coffee has always held that relying on processing methods to alter coffee's performance is not a sustainable strategy—consumers mostly approach special processing methods with a curiosity for novelty, while traditional processing methods are what they are truly willing to accept long-term. If traditional processing methods are applied to Catimor, it can also present a pleasantly enjoyable cup after brewing. So how can the public be left with a good impression when drinking traditionally processed Yunnan coffee? The answer is to start from the source—the variety. At its Baoshan estate in Yunnan, Front Street primarily cultivates Typica, precisely in the hope of leading by example and driving a transformation in the image of Yunnan coffee. This article will compare the actual differences between the two varieties, Typica and Catimor, from multiple angles including cultivation yield, estate environment, and brewing flavor. [more…]

Among the many variables in pour-over coffee, pouring technique is often overlooked by beginners, yet it has a significant impact on the final flavor. The speed of the circular pour is essentially equivalent to the amount of agitation applied to the coffee bed, so how much difference can it actually make to the taste of the coffee? Front Street conducted comparative experiments using washed Yirgacheffe and dark-roasted Golden Mandheling, measuring concentration and extraction yield and combining this with actual tasting to verify the effect of different pouring speeds on flavor. This article will present the parameters and results of both experiments in full, and further explore the role that agitation intensity plays when conditions such as grind size are changed. [more…]

Regarding whether an electronic scale is needed when making coffee, two completely different voices have always existed within the coffee community. One side insists that a scale is a key tool for ensuring extraction quality, while the other feels that a few grams more or less makes no difference, and the taste of the espresso will not change noticeably. To verify this controversy, Front Street Coffee designed a set of comparative experiments, testing respectively from the two dimensions of different dose and different liquid weight, using actual tasting to reveal how a change of a few tenths of a gram in dose affects the flavor of espresso, and whether an electronic scale is actually necessary in daily coffee production. [more…]
