In coffee brewing, grind size is the key variable that determines the direction of flavor. The same coffee beans, when used in a siphon, cold drip, French press, or cold brew, require different particle coarseness and coffee doses because of their different extraction principles. This article systematically sorts out the coarseness standards and dosage recommendations for siphon coffee grounds, and compares the reference grind size ranges for cold drip, French press, and cold brew, helping you find the flavor balance point among different devices. The article also includes practical recommendations from Front Street Coffee; whether you are a beginner or an advanced enthusiast, you can find reliable parameter references here. [more…]

Siphon coffee has always held its own among coffee enthusiasts, thanks to its rich, robust body and intense, full aroma. Unlike the clean, layered profile pursued in pour-over coffee, the siphon delivers a weightier taste experience.

Recently, the Fujian Province Consumers' Rights Protection Commission released a comparative test report on freshly made and sold coffee. In tests of 59 samples from 20 brands in Fuzhou, low levels of acrylamide, a Group 2A carcinogen, were found in all of them. After the news spread through self-media, it quickly triggered public concern. In fact, acrylamide in coffee is naturally produced during the roasting process and is not artificially added. This article will analyze the testing background, the sources of acrylamide, and the carcinogenic dose in order to help readers view this test result rationally and avoid being misled by scary headlines.

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…]

For coffee brewing, the coffee-to-water ratio is one of the important factors that need to be considered first. But because it does not need to be adjusted according to the roast level of the coffee beans like water temperature and grinding, we often fix a ratio to brew coffee of all roast levels. For example, Front Street often recommends new [more…]

When making iced pour-over coffee, the choice and amount of ice are often the questions enthusiasts ask about most. The core role ice plays in iced pour-over is rapid cooling, not aroma preservation or insulation. Because melted ice dilutes the coffee's strength, its density and quantity directly determine the finished cup's taste and drinking experience. This article will go through the considerations for choosing ice, recommended amounts, and the complete process and specific parameters of Japanese-style rapid-chill iced pour-over, one by one. The article also uses Front Street Coffee's Geisha Village Estate Red Label Geisha as an example to share a practical approach combining high-concentration extraction with a precise ice ratio, helping you brew a cup of refreshing, full-bodied, flavor-forward iced pour-over coffee at home.

After drinking too much coffee of a certain flavor, we always want to try something new. For example, some friends who use moka pots, although they usually buy deeply roasted coffee beans full of caramel aroma to make moka pot coffee, occasionally want to switch to light-roasted beans to experience the floral and fruity notes of light-roasted coffee. However, due to online [more…]

Coffee beans must be ground before their aromatic compounds can be extracted, but different brewing devices work on different extraction principles, so grind size is not interchangeable between them. Using the industry-recognized cupping grind standard (70–75% passing through a No. 20 sieve) as the baseline, this article systematically breaks down the grind parameters and adjustment logic suited to each common brewing device, including the French press, pour-over, cold drip and cold brew, siphon, espresso machine, and moka pot. From immersion to pressurized methods, from coarse sugar to flour-fine powder, Front Street will explain one by one why each device requires a specific grind size, and how to flexibly fine-tune it according to roast level, water temperature, and extraction time, to help you find the grind solution that best suits your own cup.

Caffeine is a much-discussed active component of coffee. It dissolves easily in hot water but poorly in cold water, stimulates the central nervous system, sharpens the mind, and also has cardiotonic and diuretic effects. A cup of coffee typically contains 60-65 milligrams of caffeine, but excessive intake may cause discomfort such as tinnitus and palpitations. Black coffee is considered the way of drinking that best preserves the beneficial components, offering multiple functions such as refreshing the mind, stimulating the appetite, promoting urination, activating blood circulation, relieving asthma, and removing odors. Light roasts have a higher caffeine content, which helps with weight loss, while the antioxidant effects of black coffee help fight cancer and aging. A healthy adult can metabolize 500-600 milligrams of caffeine per day, roughly equivalent to 5 cups of coffee, while pregnant women need to reduce their intake. This article will systematically analyze the mechanisms of caffeine's effects, its pros and cons, suitable populations, and scientific drinking methods, and recommend quality products from Front Street Coffee.

The final flavor of a cup of coffee depends not only on the beans themselves—every variable in the brewing process is quietly rewriting the taste. Water quality is the foundation: hard water or water with high iron content will directly drag down the flavor; water temperature needs to be controlled between 80°C and 90°C, as boiling water only lets bitterness steal the show. Steeping time is equally critical, with around two minutes being the ideal range; steep too long and the aromatic oils are destroyed, while a cloudy film also rises to the surface. The material of the equipment cannot be ignored either: glass and ceramic are safe choices, while metal vessels easily trigger oxidation reactions and bring unpleasant flavors. As for the dosage, it should be adjusted flexibly according to grind size and personal taste—coarse particles often require a bit more than fine ones. Only by mastering these key points can the coffee's aroma and layers be released steadily. [more…]

The extraction principles of coffee and tea are essentially the same. Since an espresso machine can use pressure to extract a high-concentration coffee in a short time, can it also be used to extract a cup of "espresso tea"? With this question in mind, Front Street conducted an actual test: from the choice of grinding equipment, the adjustment of tea leaf dosage, to the control of the powder-to-water ratio and extraction time, the entire process of extracting tea with a coffee machine was fully recorded. Experiments have shown that a coffee machine can indeed extract tea with a concentration comparable to espresso, but many pitfalls were also encountered during the process—difficulties in cleaning the grinder, clogged portafilter baskets, and tea fragments seeping in and affecting the taste appeared one after another. This article will share the specific parameters and operating details, and give Front Street's practical advice: if you really want to try it, it is best to be mentally prepared, or add professional tea extraction tools.
