Among the many variables in pour-over coffee, grind size is often the hardest to describe precisely in words. Every enthusiast uses a different grinder, so when baristas communicate with customers, they usually have to rely on everyday seasonings as analogies. Although this approach has its limitations, it is an effective way to quickly establish a brewing framework. This article will systematically sort out the applicable scenarios for four grind reference points—fine salt, fine granulated sugar, coarse granulated sugar, and sea salt texture—and, using a natural-process red cherry coffee as an example with the MAVO Wizard 2.0 manual grinder, demonstrate how to gradually "blind-test" your ideal setting when faced with an unfamiliar grinder by observing the bloom pattern, drawdown time, and coffee grounds condition, helping you find your own cup of good coffee.

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…]

Mandheling coffee is the signature of Indonesia's Sumatra region, known for its full-bodied richness, subtle acidity, and understated character. Front Street Coffee conducted a blind tasting in which baristas cupped the coffees without knowing the identity of the beans, and the result was that PWN Golden Mandheling was identified the fastest. Also present was a Front Street Gayo Golden Mandheling; both come from the same region and both use wet-hulling processing, so where exactly do they differ? This article starts with Front Street Coffee's blind tasting, outlines the growing background of the Gayo Mountain region, compares PWN Golden Mandheling and Front Street Gayo Golden Mandheling in terms of variety, screening standards, and flavor performance, and includes Front Street Coffee's roasting records and brewing parameters to help coffee lovers understand how Mandheling coffee should be enjoyed.

In an era where self-media tutorials are everywhere, beginners often blame their brewing technique when coffee doesn't taste good. But can technique really turn something mediocre into something magical? Starting from the dissolution patterns of flavor compounds, this article analyzes how the alternation of washing and soaking during pouring affects extraction efficiency, and uses the comparison between the three-pour method and the one-pour method as an example to reveal the source of differences in sweetness. At the same time, through blind tasting experiments, Front Street Coffee shows that what ultimately determines the ceiling of a cup of coffee is still the beans themselves. Technique can only add the finishing touch; choosing the right beans is the key. [more…]

It sounds like a cliché, but this summer really is scorching hot! There are many ways to beat the blazing summer heat, and in the coffee world, the best solution is of course the wildly popular cold brew coffee of recent years.

"How big of a difference can there be between coffee with a 30-second bloom and a 60-second bloom?" This was a question a friend asked Front Street Coffee yesterday. I have to say, this question is actually quite interesting! As we all know, blooming is a routine step in pour-over coffee. Specifically, before the official pour, we pre-pour [more…]

The scorching summer is hard to endure, and cold brew coffee has become the top choice for many coffee lovers to beat the heat. Starting from the underlying principles, this article explains clearly why cold brew coffee tastes more balanced, then walks through step by step the types of coffee beans suitable for cold brew, the reasonable range for the coffee-to-water ratio, how grind size and steeping time work together, and how long it can be kept once made. The article also gives specific recommendations based on several Front Street Coffee beans, including the dark-roasted Queen's Estate, PWN Golden Mandheling, the light-roasted Fruit Ding Ding, Little Tomato AA, as well as the specially processed Strawberry Candy and Front Street Xizhua, to help you avoid detours and make a smooth, consistent cup of cold brew at home.

What exactly is the coffee bean grading system based on? Does bean size directly determine flavor intensity? To answer these questions, Front Street Coffee specially selected Costa Rican Mozart beans for a cupping comparison experiment, sorting the same batch of beans into large, medium, and small sizes, then taking the largest and smallest two beans for a blind extraction test. The results showed that the two did indeed differ slightly in flavor, but the direction was unexpected—the small beans actually had a more prominent flavor than the large beans. However, this difference mainly came from the degree of roasting deviation caused by different particle sizes, rather than the bean size itself. What truly determines coffee flavor is genetics, growing environment, processing method, and roasting degree. This article will combine experimental data with industry theory to systematically sort out the logic of coffee bean grading and the real factors affecting flavor. [more…]

Kenyan coffee is renowned for its vibrant berry notes, lively acidity, and substantial body, and its unique Kenyan-style washing process and green bean grading system based on bean size are equally noteworthy.

Every morning, the first hurdle a barista faces is often not latte art, but getting the taste of espresso back on track. Coffee bean conditions and weather are constantly changing, and extraction results fluctuate accordingly. How can you find the right grind setting using the fewest beans and the shortest time? This article starts from taste, first determining whether the espresso is under-extracted or over-extracted, then uses a 1:2 coffee-to-water ratio and an extraction time of about 30 seconds as the baseline framework, correcting flavor through fine adjustments to the grind size. The article also uses Front Street Classic Blend as an example to fully demonstrate the three-step dialing process—from 23 seconds of sharp acidity to 31 seconds of balance, then fine-tuning the yield to finish—helping readers build a reusable debugging logic.
