In the practice of pour-over coffee, the coffee dose is one of the key variables determining the extraction result. Many coffee enthusiasts run into this problem: at the end of a bag of beans there are always a few grams left, too little for a single cup on its own, yet too wasteful to throw away. Based on Front Street Coffee's hands-on testing experience, this article systematically explores the differences between brewing with a small dose of around 7 grams and a conventional 15-gram dose, analyzes the extraction challenges caused by a thinner coffee bed and faster water flow, and offers two sets of adjustment plans for different levels of water-control skill—one that relies on a finer grind combined with a thin stream and three-pour approach, and another that uses a heavy stream and staged raising of the water level to lower the barrier to execution. Whether you are a complete beginner or a pour-over player with some experience, you can find a small-dose strategy that suits you. [more…]

When the coffee dose for pour-over is increased to multiple servings, key parameters such as the amount of water poured and the pouring time will change accordingly.

The blooming phase in pour-over coffee seems simple, yet the choice of water amount often sparks debate: some insist on twice the coffee dose in water, while some shops advocate that four times the water amount allows for more even degassing. Front Street Coffee conducted a controlled experiment using an Ethiopian Chaka bean, fixing the dose at 15g, the coffee-to-water ratio at 1:15, the water temperature at 92°C, the grind size at a 75%~80% passing rate through a No. 20 sieve, and the total time at 2 minutes, changing only the blooming water amount (30ml vs 60ml), then comparing the differences between the two brews through sensory evaluation and concentration meter measurements. The results showed that the coffee bloomed with twice the water amount had a concentration of 1.54% and an extraction yield of 21.2%, with a richer and more solid flavor; the one bloomed with four times the water amount came in at 1.48% and 20.36%. The article further explains the principle of degassing during blooming, why conventional brewing defaults to twice the water amount, and why special techniques such as the stirring method require more water for blooming, helping you find a blooming strategy that suits you.

The V60#01 dripper is typically suited for 1 to 2 servings, with 15 to 20 grams of coffee being its optimal working range. But in reality, when drinking alone and not wanting too much, people reduce the dose, and when sharing with friends, they increase it. So, when brewing different doses in the same dripper, do the parameters really need to be changed? Front Street Coffee conducted three sets of comparative experiments using Ethiopian Yirgacheffe natural Red Cherry, with doses of 10 grams, 15 grams, and 25 grams, a fixed water temperature of 90°C, a 1:15 coffee-to-water ratio, medium-fine grind (80% passing through a Chinese standard No. 20 sieve), and circular pouring. The results showed that with a smaller dose, the flavor tends to be thin, while with too large a dose, bitterness may appear and the liquid level may awkwardly approach the rim of the cup. This article will break down the three brewing recipes one by one, their flavor performance, and the adjustment approaches for 10 grams and 25 grams, to help you find a more reasonable extraction method in this small dripper.
