What's the difference between a smart cup of coffee and a smart cup? Advantages and disadvantages of coffee smart cup

Guide sometimes, want to drink a cup of black coffee, but do not want to use "tedious" hand flushing method (many utensils). Then as a simple soaking type of coffee utensils appear to be very advantageous, among which smart cups and French pots are the most classic. So how to choose these two kinds of coffee utensils? Smart Cup is a very convenient coffee brewing apparatus, which can complete the process of soaking and filtering coffee, saving a lot of operation. The key to the design of the smart cup lies in the piston valve at the bottom of the filter cup. After boiling water is injected into the filter cup, the water pressure will make the piston valve close and stop the water automatically, and the coffee powder can be fully soaked in it. After soaking, place the filter cup on the mug, press the chassis to open the piston valve, and the coffee will slowly flow into the cup.

The pressure kettle, which originated in France in 1850, is a simple brewing apparatus composed of a heat-resistant glass bottle and a metal filter with a pressure bar. Its working principle is to soak the coffee, and then press the coffee residue down with a metal filter with a pressure bar to get a clean cup of coffee.

So what's the difference between the coffee made by the two? These two coffee utensils have both common points and characteristics, Qianjie intends to make a comparison, since it is the same soaking type, so use the same coffee beans and brewing methods. Choose the Kenyan Asalia coffee beans from the front street coffee, which is a coffee with bright acidity and full taste. The cooking parameters are as follows:

Powder quantity: 15g powder / water ratio: 1:15 Grinding degree: medium grinding (standard sieve 20 pass rate is 70%) Water temperature: 94 ℃ soaking time: 4 minutes Smart Cup: cover with filter paper, pour in 15g coffee powder, prepare 225g hot water to pour into the cup, close the lid and wait for 4 minutes. Then put the smart cup on the mug and wait for the coffee to be dripped.

French pressure pot: pour 15g coffee powder, prepare 225g hot water to pour into the pot, pump pressure rod, close the lid, wait for 4 minutes. Then slowly press down the pressure bar until the strainer is located in half of the pot, and pour the coffee liquid into the mug.

Comparing the two flavors to observe the coffee liquid, the smart cup is more clear and thorough, while the French pressure kettle will appear turbid, and the surface is still floating with oil. Taste, bright sour cup, lemon, virgin fruit and maple syrup flavor, the overall cleanliness is strong, the flavor is slightly light. The French kettle shows the flavor of black plum, berry and virgin fruit. It has a strong, round but rough taste.

The reason for the different flavor is that the coffee powder and water move each other only at the beginning of the water injection in the smart cup, and the rest of the time is basically at rest, including the part where the water drips into the mug later. Most of the water flows into the cup through the ribs, coupled with the filtering effect of the filter paper, making the coffee clean, bright and clear. In addition to the movement of powdered water at the beginning of water injection, the coffee powder was later moved downwards when pressing the bar, which improved the extraction efficiency, and the kettle filtered coffee grounds through a metal filter, which had a larger pore diameter than ordinary filter paper, so it could retain most of the coffee oil and some fine powder, so the liquid surface would appear muddy and taste round.

So, how to choose? For those who like cleanliness and convenience, it is recommended to use a smart cup, because of the filter paper, the cleanliness of the coffee will be improved, and the subsequent cleaning will be easier, compared with the French kettle, the French kettle should clean the coffee grounds and the fine powder and grease attached to the filter screen and glass wall.
