FrontStreet Coffee - Hand Pour Coffee Extraction Time

Emphasizing the concept of "precise weighing and timing," if you want to consistently produce delicious coffee, weighing and timing are indispensable!

Unlike tea leaves that can be brewed multiple times, coffee brewing is a "one-shot deal." Coffee grounds should be precise to 0.1g, brewing water weight precise to 1g, and only with the appropriate ratio can you brew the most delicious coffee. To solve the problem of precisely measuring coffee grounds and water weight, you only need to use an electronic scale that can be accurate to 0.1g.

When making hand-pour coffee each time, please pay more attention to the overall brewing time (from the first drop of water contacting the grounds to removing the filter cup). Coffee brewed in 90 seconds (removing the filter cup when the time reaches 1.5 minutes, perhaps with some coffee liquid still remaining in the filter cup) and coffee brewed in 3 minutes (removing the filter cup after all coffee liquid has finished dripping at 3 minutes) will definitely have different flavor profiles. The longer the brewing time, the higher the extraction rate. Friendly reminder: When brewing single-serving (around 15g) coffee grounds, try to keep the total brewing time within 2 minutes. Exceeding 2 minutes can easily release the later-stage flavors of coffee extraction (bitterness and astringency).

First Pour

After 20 seconds of blooming, begin the first pour. Including the blooming water amount, pour to around 120ml. This pour should be completed in about 30 seconds.

Key Points:

1. Keep the kettle spout as close as possible to the surface of the bloomed coffee grounds. This is to prevent large bubbles from breaking through the grounds surface during pouring, which would cause loss of coffee aroma.

2. Start pouring from the center, slowly expanding the pouring radius. Please always maintain a distance of more than 1cm between the maximum outer diameter of pouring and the filter paper.

This is done to ensure the entire coffee grounds wall is not broken through, ensuring coffee extraction is achieved through uniform permeation of the coffee grounds wall. If the coffee grounds wall is broken through, it means "direct water" has occurred - water has reached the serving pot directly without permeating through the coffee grounds wall. Such coffee will be bland and lacking in layers.

The next two pours should also pay attention to this requirement.

Second Pour

间隔 about 10 seconds from the first pour. Please start the second pour before the grounds surface begins to collapse. Including the blooming and first pour water amounts, the total should reach around 220ml. This pour should be completed in about 30 seconds.

Start pouring from the center, slowly expanding the pouring radius. Please always maintain a distance of more than 1cm between the maximum outer diameter of pouring and the filter paper. The kettle spout should still remain as close as possible to the bloomed coffee surface. If brewed properly, a regular circular layer of fine foam and oils will form on the coffee grounds surface - this is the pouring range we want to maintain.

Third Pour

间隔 about 10 seconds from the second pour, paying attention to start the third pour before the grounds surface begins to collapse. Start pouring from the center, slowly expanding the pouring radius. Please always maintain a distance of more than 1cm between the maximum outer diameter of pouring and the filter paper. The coffee grounds have now fully absorbed water and become heavy, so the kettle spout can be slightly higher for this pour, about 10cm from the coffee grounds surface. The water should be steady, fully mobilizing the coffee particles.

Knowledge Point:

The rate value of soluble substances in coffee particles is related to the amount of surface area contact between coffee grounds and water.
