Many people who are just getting into pour-over coffee feel that the barrier to entry is high, but in fact, as long as you grasp the four core parameters of grind, water temperature, ratio, and time, brewing good coffee is not difficult. This article starts from a beginner's perspective and shares three practical tips for getting up to speed quickly: first, learn how to taste a cup of coffee, and build flavor judgment through drinking more and comparing, using cupping when necessary to understand the normal state of the beans; second, develop the habit of record-keeping, systematically tracking bean information, brewing parameters, and final performance, and learn to control variables to understand the impact of each parameter on extraction; finally, on the basis of familiarity with the logic of the parameters, adjust flexibly and make targeted corrections for problems such as under-extraction. In the article, Front Street Coffee uses Huakui as an example, giving specific parameters and adjustment ideas to help beginners avoid detours. [more…]

Many people new to pour-over coffee tend to focus on pouring techniques, but Front Street believes that what really determines whether a cup of coffee tastes good is whether the extraction parameters are reasonable. The differences between single-pour, three-stage, and 4:6 methods are essentially differences in parameter configuration. This article starts from Front Street's practical experience, first sorting out the underlying logic of grind size, water temperature, and ratio, then sharing a simplified approach that requires almost no water-control skill—paired with a cake filter cup, you simply bloom and then pour all the remaining hot water in one go, reliably producing a coffee with balanced sweetness and standout sweetness. Using Front Street Ethiopia Huakui as an example, the article lists in detail a parameter comparison between the conventional three-stage method and this simplified brewing method, making it easy for everyone to reproduce at home.

Freshly roasted coffee beans often carry a large amount of carbon dioxide and a harsh, dry sensation. Brewing them directly will greatly diminish the flavor, and the cup will not be smooth enough to drink. This article addresses this common problem by outlining three practical solutions for dealing with fresh coffee beans: first, accelerating gas release through degassing; second, adjusting parameters such as water temperature, grind size, and blooming time to improve extraction efficiency; and third, adopting immersion-based extraction, which has a higher margin for error. Using Front Street Ethiopia Hamashu coffee beans as an example, the article provides specific details on dose, water temperature, coffee-to-water ratio, and staged pouring demonstrations, and compares the flavor differences under conventional parameters, helping coffee lovers brew a relatively excellent cup even when they are impatient to drink it.

Many coffee enthusiasts have experienced this confusion: why does the same bean taste different every time it's brewed? Occasionally a stunning cup of coffee is brewed, but it's hard to reproduce afterwards, so some people attribute coffee extraction to "metaphysics." But in fact, extraction is a quantifiable, reproducible scientific process. Water acts as a solvent, dissolving the flavor substances from the coffee grounds, while parameters such as grind size, water temperature, time, and coffee-to-water ratio all directly affect extraction efficiency, and thereby determine the final flavor in the cup. Taking Ethiopia Huakui as an example, Front Street uses 15g of grounds, a 1:15 coffee-to-water ratio, caster sugar grind size, and a two-minute three-pour brewing method to consistently obtain a coffee with balanced acidity and sweetness, carrying citrus, strawberry, and creamy floral aromas. This article will systematically explain how to achieve flavor stability and targeted adjustments by recording and controlling parameters, and explain the scientific logic behind the differences in dissolution rates of sourness, sweetness, bitterness, and saltiness.

Among pour-over coffee equipment, cone-shaped drippers and flat-bottom drippers are two completely different choices. The cake dripper gets its name because its filter paper resembles baking paper, and its flat bottom brings extraction characteristics opposite to those of the V60: the coffee bed is thinner and more uniform in depth, pouring does not require deliberately controlling the range, and even beginners can easily brew a balanced and full-bodied cup of coffee. Of course, the relatively slow flow rate also requires us to make targeted adjustments in our parameters. In this article, Front Street will analyze the structural principles and flavor tendencies of the cake dripper, and share a specific method for brewing Ethiopian Hamashu with the Origami dripper, including coffee dose, water temperature, grind size, and staged pouring technique, to give you a comprehensive understanding of the advantages and disadvantages of flat-bottom drippers.
