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…]

How exactly should the coffee-to-water ratio for pour-over coffee be set? How much water is actually needed for 15 grams of coffee grounds? This is a common confusion for many enthusiasts. Starting from a controlled experiment at Front Street, this article visually demonstrates how the coffee-to-water ratio affects coffee strength: with all other conditions unchanged, brewing at three ratios of 1:10, 1:15, and 1:20 yielded measured strengths of 1.93%, 1.35%, and 1.04% respectively. Through this set of data, you will clearly understand the inverse relationship between water volume and strength, and learn to adjust your own brewing plan accordingly. [more…]

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…]

Should ice be added before or after brewing when making iced pour-over coffee? This question puzzles many coffee lovers. Front Street Coffee conducted a controlled experiment using 15 grams of Kaffa Forest coffee beans, a 1:10 coffee-to-water ratio, a water temperature of 90-91°C, and a grind setting of 9 on an EK43s grinder, testing two brewing sequences: ice added first and ice added last. The experiment found that after thorough shaking, the two methods performed quite similarly overall, but the coffee with ice added first tasted cleaner and more refreshing, while the one with ice added last had a more concentrated and intense aroma. The root of the difference lies in how much ice melts. This article will present the complete experimental parameters, step-by-step procedure, and sensory comparison results to help readers understand how the timing of ice addition affects the flavor of iced pour-over coffee.

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…]

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…]

Among the many variables in pour-over coffee, water temperature has a particularly direct impact on the extraction result. It not only determines the speed and sequence with which flavor compounds are released from the coffee, but also ultimately shapes the acidity, sweetness, bitterness, and body of a cup of coffee. In this article, through comparative experiments conducted by Front Street Coffee using washed Yirgacheffe beans, five water temperature groups of 80°C, 86°C, 90°C, 93°C, and 96°C were used for brewing, recording the flavor differences and analyzing the relationship between water temperature and extraction yield and concentration. At the same time, the article also provides the recommended water temperature ranges for light-roasted and dark-roasted coffee beans in daily brewing, helping coffee enthusiasts make more suitable choices for different beans.

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.

When making iced pour-over coffee in summer, the most agonizing decision is often not which beans to choose, but exactly how much ice to throw in. Too little ice and the coffee turns lukewarm; too much and it becomes thin as water. A slight deviation in ratio and it's easy to mess up. This article focuses on the two core functions of ice in iced pour-over—cooling and dilution—breaks down the reasonable ratio range among coffee grounds, water, and ice, and shares a comparative experiment about old ice versus young ice. The experiment uses 15 grams of Emerald Estate Green Label Geisha with a Hario V60 dripper, revealing through actual testing how freezing time affects ice hardness and melting speed. If you also want to consistently make a cup of iced pour-over at home with moderate strength and lasting chill, the following content is worth reading to the end. [more…]

Using a moka pot to brew estate-grade single-origin beans strikes many people as a waste of good coffee: shouldn't good beans be used for pour-over? But if you look at it from another angle, the moka pot is a very low-barrier high-concentration extraction device for home use, and expressing estate beans in a different way often reveals a side you can't see in pour-over. This round of experiments is about taking a few [more…]

The three-pour method is a common pouring technique in pour-over coffee, but many enthusiasts are unclear about how exactly the water should be divided between the two pours after the bloom. This article uses 15 grams of coffee at a 1:15 coffee-to-water ratio, selecting Front Street 2013 Yunnan Arabica Typica for a comparative experiment, setting up three schemes: a larger second pour, two equal pours, and a larger third pour, and analyzes the flavor differences in terms of acidity, body, and aftertaste. The experiment shows that the more water allocated to a given pour, the higher the extraction efficiency of soluble substances during that stage, and that the height of the coffee bed wall and the rate of water level descent are key references for judging the pouring rhythm. [more…]
