In the heat of summer, a refreshing glass of cold brew is the go-to choice for many coffee lovers looking to beat the heat. But have you ever considered that coffee beans blended from two or more varieties can also produce an outstanding cold brew? Cold brew, due to its low-temperature, long-duration extraction, has a richer, smoother mouthfeel, yet its floral and fruity notes gradually fade with storage time. This article draws on the hands-on experience of Front Street Coffee, first outlining the characteristics of cold brew and the advantages of blended beans, then recreating several blending experiments one by one: from Sidra with Geisha, Pacamara with Red Cherry, to Huakui paired with Strawberry Candy and Wangshan Geisha, and finally challenging the dark-roasted Queen's Estate blended with Flower God. Some of these recipes are full-bodied and layered, while others flop into a "mask of pain," yet they perfectly showcase the fun and possibilities of blended cold brew. [more…]

When brewing coffee, water quality, cooling methods, and tasting cup types are often treated as independent variables, but can combining all three lead to more significant sensory improvements? Front Street Coffee designed a controlled experiment using Huakui beans as samples: one group used regular mountain spring water, no ice ball, and a standard espresso cup, while the other used a custom water concentrate, a Paragon ice ball, and an aromatic tasting cup, with completely identical brewing parameters. Through concentration measurements and blind tasting, the actual contributions of these tools at different stages were verified. This article documents in detail the TDS control of the custom water concentrate, the cooling mechanism of the Paragon ice ball, and the aroma-concentrating effect of the tasting cup, and invited colleagues and customers to participate in a blind selection. The final results were highly consistent, providing coffee enthusiasts with a reproducible reference for combined techniques. [more…]

Where do the flavor differences between cold brew and hot brew lie? This article will explore the definition of cold brew, its characteristics, coffee bean selection, and more, and introduce two beans recommended by Front Street Coffee: Yirgacheffe Gutingding and Panama Butterfly. Finally, it will share creative cold brew methods such as adding sparkling water, milk, or alcohol, to help you find the cold brew solution that suits you best. [more…]

Ice drip coffee and cold brew coffee are two common methods of making cold coffee, and the two differ noticeably in production process, extraction time, and final flavor. Front Street Coffee conducted a synchronized experiment using the same sun-dried Huakui coffee beans, comparing the production methods and resulting performance of ice drip and cold brew in an all-round way, from grind size calibration to powder-to-liquid ratio setting, and then to extraction time and post-processing methods. The experimental results showed that ice drip coffee was clear and bright, with a clean and refreshing mouthfeel, carrying fermented notes and a faint berry-like sweet acidity; cold brew coffee, by contrast, had a full-bodied mouthfeel and uniform flavor, with prominent fruity sweetness and a weaker fermented note. This article will analyze in detail the differences in production methods between the two types of cold coffee, the experimental plan, and the flavor comparison results, to help coffee enthusiasts more clearly understand the characteristics of both and the basis for choosing between them.

The most fascinating thing about cold brew is that it works like a slow-motion projector: the flavor release that hot extraction completes in a few dozen seconds is stretched out over more than ten hours, and the character of every flavor compound is amplified and put on display. Running a set of cold brew comparison experiments with beans processed in different ways lets you directly see how each processing method truly expresses itself at low temperatures. The experiment is set [more…]

Cold brew coffee, through its low-temperature slow extraction, presents a flavor profile completely different from pour-over, and is deeply loved by coffee enthusiasts. Based on the practical experience of Front Street Coffee, this article systematically reviews the origin of cold brew coffee, the extraction principles, suitable bean selection, and key operational points, and shares a variety of cold brew recipes centered on beans such as Yirgacheffe, Kenya, and Mandheling, covering dark berry type, refreshing and clean type, sweet and delicious type, as well as blending ideas. The article also explains in detail the production steps, fermentation duration, and drinking suggestions, helping you make a cup of cold brew coffee with full aroma and smooth mouthfeel at home.

Cold brew coffee usually requires 8 to 12 hours of low-temperature slow extraction, but what if you want to drink it the same day? Raising the water temperature can speed up extraction, but if you use hot water directly, it becomes hot brew, and the floral and fruity aromas and low bitterness unique to cold brew will also disappear. Front Street compared three methods through experiments: conventional 23°C cold water extraction for 10 hours, 40°C warm water extraction for 4 hours, and 92°C hot water blooming followed by room-temperature water extraction for 4 hours. The beans used were Colombia · Hanami, with full berry acidity, floral notes, and pink pepper flavors. The results showed that the 40°C warm water rapid cold brew was closest to the performance of conventional cold brew, with both a fermented feel and clearly presented flavors, making it suitable for friends who want to drink cold brew quickly.

The flavor expression of coffee depends not only on the quality of the green beans, but is also closely related to the degree of roasting and the extraction method. In this experiment, coffee beans at three different roast levels—light, medium, and dark—were selected and extracted using two methods, cold drip and pour-over, to compare their specific differences in aroma, acidity, mouthfeel, and aftertaste. Light roast in cold drip presents fresh notes of citrus, jasmine, and honey, while pour-over shows bright acidity and a clean mouthfeel; medium roast in cold drip brings the sweetness of rose, grape, and blueberry, while pour-over presents the richness of chocolate and caramel; dark roast in cold drip has a pronounced oily body and a smooth mouthfeel, while pour-over is intense with a slight burnt bitterness. The article also recommends representative Front Street Coffee beans for each roast level, providing a reference for coffee lovers when purchasing and brewing. [more…]

Latte, Americano, and espresso share the same roots, yet they present entirely different flavor expressions due to different espresso extraction ratios. Front Street Coffee used the same specialty blend beans, the same grind size and dose, to test the specific effects of three brew ratios—1:1, 1:1.5, and 1:2—on espresso, latte, and Americano. The results showed that espresso at a 1:1 ratio was on the sour side but had a prominent sweetness after adding milk, 1:1.5 had the richest layering and a balanced latte, while 1:2 tended to over-extract and develop woody and smoky notes. The article also explained espresso's reliance on blend beans and recommended Front Street's classic espresso blend. [more…]

Many friends who are just getting into coffee have a question: which is actually better, blended coffee or single-origin coffee? Does using more types of beans in a blend make it more impressive? Because some merchants heavily promote blends of four or even more types, many beginners mistakenly believe that the number of bean varieties in a blend is directly tied to its quality. In fact, the core of blended coffee lies in the complementary characteristics and proportional adjustment among the beans, not simply piling up varieties. In this article, Front Street will systematically explain what blended coffee is, what problems it can solve that single-origin beans find hard to achieve, and, through a brewing experiment using more than thirty kinds of coffee beans, intuitively demonstrate why more beans in a blend is not necessarily better, as well as why merchants generally keep blends to 2~5 types at present.

In a cup of black coffee, water makes up the vast majority, so its impact on flavor must not be underestimated. Different brands of drinking water vary in mineral composition, hardness, and pH, so the coffee brewed with them naturally takes on different characteristics. To investigate this variable, Front Street Coffee selected four common drinking waters—Baisui Mountain, Nongfu Spring, Ganten, and C'estbon—and used the same Costa Rica Mozart coffee beans to make cold brew, measuring TDS, coffee liquid concentration, and recording flavor performance one by one. The experiment found that the amount of calcium and magnesium ions in water affects extraction efficiency and taste direction, while Nongfu Spring with medium TDS and C'estbon purified water each showed distinct stylistic differences. This article will present the full experimental process and tasting results, and offer water selection suggestions for different taste preferences. [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.

Cold brew coffee has always been made by steeping at low temperatures throughout, but if you first bloom the coffee grounds with hot water before steeping, will the final product taste better? Front Street conducted a controlled experiment using Sidamo Huakui 8.0: aside from the water temperature treatment, the two pots of cold brew had completely identical parameters—one was mixed directly with room-temperature water and refrigerated, while the other was first bloomed with 92°C hot water for 30 seconds before room-temperature water was added. After 8 hours, filtering and tasting revealed that the two had similar flavor directions, but the bloomed version had a higher concentration. The article then explains that the real source of this difference is not the blooming action itself, but the hot water and parameter changes introduced to accomplish the blooming, and, combined with the principle of degassing during blooming in pour-over brewing, explains its applicability in the cold brew scenario.

Many coffee enthusiasts at Front Street stores order both a cold brew and an iced pour-over made from the same beans, yet are often surprised by the huge gap in flavor between the two after drinking them. Why does the same coffee bean produce such an obvious difference in the resulting cup? This article will systematically sort out the core differences in brewing principles between cold brew and pour-over from multiple dimensions such as extraction water temperature, extraction method, and concentration differences, and combine a comparative experiment conducted by Front Street using Huakui 8.0 to help you understand the taste expressions brought by low-temperature slow extraction and high-temperature fast extraction, as well as the scientific logic behind these differences.

Yirgacheffe is known for its bright floral notes and citric acidity, and is generally regarded as a representative of light roasting. But when the roaster was momentarily distracted and the bean temperature shot up to 197°C, entering the middle-to-late stage of second crack, this batch of Yirgacheffe became an experiment in dark roasting. After dark roasting, the beans are darker in color and smoother on the surface, and after grinding, the aroma shifts from intense to burnt and bitter. How does it perform after drip brewing? In its youth it is charming and lively, but later it becomes simple and clear, with a lingering burnt bitterness. This article uses this accident as an opportunity to discuss the feasibility of dark-roasting Ethiopian beans, common misconceptions in blending, and why people still tend to prefer light-roasted Ethiopian beans. [more…]

In the past, the iced pour-over recipes we shared mostly involved pouring hot coffee directly over ice to cool it down—a Japanese-style approach. This time, Front Street Coffee wants to try something different—extracting coffee with ice water the whole way through. Ice water is low in temperature and poor at extraction, so it may not seem very reliable, but once you understand the balance between grind size, water temperature, and pouring method, you can actually find a reasonable brewing path. This article will first explain the idea behind brewing coffee with ice water, then use the Costa Rica Strawberry Candy bean as an example to give the dripper choice, grinding parameters, and complete brewing steps, and finally add an extra experiment using soda water instead of ice water to see how the taste changes.
