The brewing time of hand-brewed coffee is recommended as a tutorial: how long does it take to make a cup of hand-brewed coffee?

How long is it appropriate to cook by hand?

If you simply want to know that the coffee time you brew is not right, the front street directly gives the conclusion here, based on the amount of 15g powder in the filter cup of No.01, the overall time is controlled within 1 minute 50 seconds-2 minutes 30 seconds, which is a better range of brewing time.

We usually say coffee, with professional expression is coffee extraction, that is, the use of hot water as a carrier to dissolve the flavor substances in coffee powder, this process takes time, usually, the longer the extraction time, the more substances extracted coffee, but coffee can dissolve substances are not all good. Therefore, it is necessary to control the extraction time.

In general, drip coffee in about 2 minutes, coffee powder quickly released soluble substances, extraction rate can reach 18%(18-22% is considered a good extraction range in the gold cup criteria);5 minutes later will dissolve more than 80% of soluble substances. (More than 24% of coffee beans)

To put it another way, for example, when we use the normal brewing mode, the extraction time of coffee is much earlier than 2 minutes, and there may be insufficient coffee taste, weak, and watery, while the extraction time is much longer than 2 minutes, and there may be a burnt bitter taste caused by excessive extraction.

Therefore, the extraction time is controlled between 1 minute and 50 seconds and 2 minutes and 30 seconds, and the flavor of coffee will be better. If we want to master coffee flavor, we must understand at least a few factors that can affect time.

What affects coffee extraction time?

1. Coffee grinding degree. Coffee powder thickness will affect the speed of water, coarse coffee powder water will be faster, extraction time is relatively short; fine coffee powder water will be slower, extraction time is relatively long. If you want to control the extraction time of about 2 minutes, the recommended grinding thickness of the front street is 75-80% of the pass rate of the No. 20 sieve.

2. Filter cup. Use V60, ice pupil, stream flow these more guide groove filter cup, water will be a little faster; use Kono, fan filter cup water will be a little slower. It'll be about 20 seconds apart.

3, water injection method will also affect the extraction time, such as large water injection extraction time will be shorter than small water injection.
