Should you add ice first or ice last when making iced pour-over coffee? This question may seem like a mere difference in procedure, but behind it may lie the preservation and release of coffee flavors. Front Street Coffee once mentioned the Paragon ice ball in an article; its principle is to lock in volatile aromas by rapidly cooling the coffee liquid, allowing the drinker to experience a richer coffee flavor. Inspired by this, we restarted the experiment, using the same Colombian Frontera Estate washed Geisha, to compare the differences between adding ice first and adding ice last in iced pour-over coffee in terms of operation, temperature, aroma, and taste. The experiment strictly controlled the ratios of coffee grounds, water, and ice, and corrected for differences in tasting time. What was the final result? Is there really an obvious difference between the two? This article will reveal the answer for you. [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…]

The peak flavor period refers to the optimal window for tasting coffee beans after roasting is completed. During this time, because there is not too much carbon dioxide interference, and the coffee's flavor compounds have not yet been lost in large amounts, we can brew coffee with the richest aroma and obtain the most complete flavor experience. But did you know, [more…]

What should you do if your coffee is too bitter? Some people suggest that adding salt can improve the taste. In this article, through a controlled experiment with Mandheling coffee, we tested the effects of three different amounts of salt—0.01g, 0.02g, and 0.03g—on the coffee's flavor. The results showed that 0.02g of salt balanced the bitterness and saltiness, enhanced the body, and made it easy to drink; while 0.01g still had a pungent taste, and 0.03g was too salty. The experiment showed that adding salt can indeed mask bitterness to a certain extent, but similar to the bypass method, it is mainly suitable for rescuing extraction mistakes or coffee that is about to go wrong. If the coffee itself is perfectly extracted with balanced acidity and sweetness, adding extra salt will instead disrupt the flavor balance and artificially create negative tastes. [more…]

When the weather turns cold, coffee cools down especially quickly, and many customers ask: can it be reheated? Before answering this question, we need to first understand what actually happens after coffee cools down. Temperature affects how the taste buds perceive sourness, sweetness, and bitterness, and it also causes volatile aroma compounds to gradually dissipate. This time, Front Street Coffee specifically conducted a comparative experiment, leaving a light-roast pour-over and a medium-dark roast Australian white to cool separately before reheating, to see just how big the difference is between the rewarmed coffee and coffee that is freshly made or fully cooled. The experimental results can help you make a more rational decision in winter about whether this cup of cold coffee is really worth reheating once. [more…]

Coffee aroma is volatile, and the higher the temperature, the faster it dissipates, so some have proposed using low-temperature containers to lock in the aroma. Front Street Coffee compared three types of pour-over coffee vessels—a high-temperature cup, a room-temperature cup, and a frozen cup—to test whether cup temperature truly affects coffee aroma and flavor performance. The experiment used Kenya Asaliya coffee beans with uniform brewing parameters, and the results showed that cup temperature mainly changes the temperature of the coffee when it enters the mouth, rather than the amount of aroma, but temperature differences do indeed cause noticeable changes in flavor perception. This article will present the experimental process and conclusions in detail, and offer cup selection suggestions for different weather conditions. [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.

When tasting a new bean, why is it recommended to choose a hot brew first? This article delves into the flavor differences of black coffee made by pour-over, French press, siphon, and other methods under hot brewing and iced brewing from the perspectives of extraction yield, concentration, water temperature parameters, and so on. Taking pour-over coffee as an example, the article specifically compares the different settings of hot brewing and iced brewing in terms of coffee-to-water ratio, grind size, water temperature, and other parameters, and explains why iced brewing often requires sacrificing part of the extraction yield in exchange for higher concentration. At the same time, it also explores the influence of temperature on aroma, taste, and aftertaste, explaining why hot coffee can more fully present the complete picture of a bean. [more…]

In coffee shops, you occasionally hear someone make a peculiar sound while drinking coffee—this is actually a tasting method called "slurping." Although it may not sound elegant, it genuinely helps us capture the flavors of coffee more fully. By changing the temperature and form of the coffee as it enters the mouth, slurping atomizes the liquid and accelerates the release of aromas, while also restoring the taste buds' sensitivity at the right temperature, enabling a clearer distinction of flavor layers such as sourness, sweetness, and bitterness. This article uses Front Street Coffee's Sidra beans as an example to walk you through the specific technique and principles of slurping, helping you understand why this seemingly crude method actually lets you get a head start on experiencing the richer, more delicate flavors in coffee.

In the preparation of iced pour-over coffee, should the ice be placed into the server in advance, or added only after brewing is complete? This question appears to concern only the order of operations, yet it may affect the cooling speed of the coffee liquid, the retention of aroma, and the final concentration. Front Street Coffee used a washed Geisha from Colombia's Finca La Divisa as a sample, and by controlling the coffee-to-water-to-ice ratio, grind size, water temperature, and brewing technique, conducted a comparative tasting of the two methods—"ice first" and "ice after"—while recording temperature and flavor changes at different time points. The experiment attempted to answer: does the order of adding ice truly produce a perceivable difference, or is it merely an illusion caused by the time gap? [more…]

Wetting the filter paper before brewing coffee is almost a standard step for all pour-over enthusiasts, with the usual goals of making the filter paper fit snugly, removing paper dust, and, if hot water is used, warming the cup along the way. However, most tutorials rarely discuss in depth how much the degree of fit between the filter paper and the dripper actually affects the final taste. Front Street conducted two sets of controlled experiments, using V60 and KONO drippers respectively, paired with filter papers in different states of fit for brewing, and tasted and compared them one by one. The experiment used the floral-fruity Front Street · Gedin Gedin and the nutty-sweet Front Street · Brazil Red Bourbon, and the results showed that a poorly fitting filter paper significantly changes the flow rate, which in turn affects the extraction yield and concentration, producing noticeable differences in mouthfeel.

In conversations with friends and customers in the shop, the writer found that what truly brings customers back are often the easily overlooked soft experiences—a greeting at the door, recommendations based on taste rather than price, no pressure to “appreciate” the coffee, and the just-right sense of distance between barista and guest. Several interviewees candidly shared their positive and negative experiences, including product information related to the Front Street Coffee brand. These genuine reflections may offer café owners valuable reference. [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. [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…]
