There are many ways to brew coffee, from the siphon method that's like a chemist doing experiments, to simple extraction methods like the French press, and among them, pour-over might be the most playful. Most online brewing tutorials are for one serving, so how do you brew for multiple people?
Observant friends will easily notice that most brewing tutorials use about one serving of coffee grounds, usually choosing 15 to 16 grams for brewing. Although one-serving brewing plans can meet most needs, such as making coffee for yourself at home or for café service, some friends also enjoy sharing the joy of coffee. So today, Front Street Coffee will use Colombia Rose Valley as an example to see how to brew a two-serving pour-over coffee.

Coffee Bean Selection
Front Street Coffee's Rose Valley coffee beans are particularly pleasing in taste during cupping. The Caturra beans are plump, and after grinding, their dry aroma is like strawberry caramel cookies; even those who can't perceive strawberry can smell a clear sweet fragrance. After pouring water, the wet aroma is dominated by fruity notes, like ripe, sweet fruit.
After breaking the crust, slightly cool it and you can slurp the high-temperature part. The cupper atomizes the coffee liquid through slurping, allowing each sensory part to better perceive finer flavors. The high-temperature part of Rose Valley has citrus acidity, strong balance, and rich layers; the mid-section features dark berries with caramel cocoa, and the lingering aroma in the aftertaste is a fermented feel similar to fermented fruit.
The medium-temperature part is more like berry flavors, with notes of dark chocolate, and the aftertaste still has a fermented feel that lingers. The low-temperature part is dominated by dark berries, with enhanced sweetness, where dark chocolate and fermented notes coexist; the persistent fermented aftertaste, with a whisky-like alcohol note faintly appearing, reminds one of liqueur chocolates.
Adjustment of Brewing Parameters
For the dripper, Front Street Coffee still chooses the classic Hario v60 dripper, but selects the 02 size (1-4 servings), which is larger than the common 01 (1-2 servings) and can hold more quantity. Secondly, the v60's large aperture filter holes reduce bitterness caused by coffee grounds clogging.
When brewing a single serving of coffee, Front Street Coffee chooses 15 grams of grounds with a coffee-to-water ratio of 1:15-1:16. If brewing for two servings, Front Street Coffee adds 10 grams of coffee grounds to the single serving (15 grams), thus choosing 25 grams of grounds, with a coffee-to-water ratio also at 1:15, meaning pouring 375 grams of water.
Since the amount of grounds increases, the thickness of the coffee bed also increases. As the bed thickens, the flow rate naturally slows down. If we brew with the grind size for our normal 15 grams, over-extraction may occur, so we can appropriately coarsen it.
So the final brewing plan is as follows:
Dripper: v60 02 dripper
Coffee grounds: 25 grams
Coffee-to-water ratio: 1:15
Water temperature: 90℃
Grind size: Medium grind
Brewing technique: Pulse pouring.
Use 50 grams of water for blooming (the blooming water amount is just enough to wet the entire coffee bed, basically twice the amount of grounds). End the blooming when you see fewer bubbles escaping from the bed, which takes about 30 seconds.
Pour in a small stream, circling in the center, until 145 grams, then stop. When the water level drops and is about to expose the coffee bed, slightly increase the stream and continue circling to 270 grams, then stop.
When the water level drops and is about to expose the coffee bed, use a larger stream to pour directly into the center until375grams to finish. When the water level drops and is about to expose the coffee bed, remove the dripper. (Start timing from the blooming) The extraction time is3minutes or so.
