Qianjie-brief introduction to coffee brewing in French pressure pot

1. Grinding thickness

No matter what kind of grinding thickness is used to grind coffee, use a high-quality flat knife or cone knife grinder instead of a blade grinder, and this brewing method is likely to lead to over-extraction. Then what exactly is the correct thickness?

A thicker grinding scale is recommended here, which is a bit like small gravel rather than fine sand. If the grinding is too fine, it may make the water extract the coffee powder too fast. It may not be a problem for other soaking utensils, but if the kettle is ground too fine, the fine coffee powder may penetrate the metal filter, resulting in a large amount of dregs precipitating in the brewed coffee.

two。 Coffee powder quantity and powder-to-water ratio

The powder-to-water ratio is a simple formula, that is, how much water to how much coffee powder, the common ratio is 1:15 (for example, 15g of coffee powder versus 225g of water). You can start from this ratio, and then increase or decrease the amount of coffee or water from the next brewing according to your preference, until you find out your favorite proportion.

3. Water temperature

Water temperature is another factor in the taste of experimental coffee. If there is no thermometer, the hot water can be boiled and left standing for 45 seconds (adjusted according to the temperature), brewing at a temperature of about 90 degrees. If you want to control the flavor of the brewed coffee, it is recommended to buy a temperature-controlled hand brewer.

4. Brewing time

The brewing time is about 3 to 5 minutes. If you brew deep-roasted coffee, 5 minutes may be too long; if it is shallow roasting, 3 minutes may be too short, so it is recommended to start with 4 minutes.

5. Brewing process

Pour the ground coffee powder into the preheated kettle, then slowly inject the hot water and make sure all the coffee powder is soaked. At first, pre-soak the steamed coffee powder with about twice the amount of water (for example, steaming 15 servings of coffee powder with 30 grams of water).

Stir gently for 30 seconds, pour in the remaining hot water, and put the pressure canister on it, do not press it down at this time, wait for the coffee powder to soak for 4 minutes, press the canister slowly to the bottom, and pour out the coffee liquid carefully to avoid stirring the coffee grounds at the bottom of the pot.

If the pressure cylinder is a little difficult to press down, it means that the coffee powder is too fine; if the coffee powder sinks and the pressure resistance is too small, it means that the grinding is too coarse.

Knowledge: 8-14 days after baking is the best taste period, the longer the coffee beans are put, the more you need to adjust the degree of grinding.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
