It is today’s protagonist, an ice-pupil filter cup that sparkles under the light and fits perfectly with the filter paper! Barista "model" in this articleIt means that using this ice filter cup to make coffee makes me feel really happy! ! ! ! ! !
What are the characteristics of the Bingtong filter cup?
Many of the coffee filter cups we see every day have protruding ribs on the cup wall, which creates a space (that is, an exhaust groove) between the filter paper and the filter cup wall. The length and direction of the exhaust groove determine the speed of water flowing through the coffee powder layer.
For example, the exhaust groove of the V60 filter cup is designed with a curved vortex rib structure (what we often call a spiral pattern). The ribs extend from the mouth of the cup to the water outlet to maximize the exhaust process of coffee powder. At the same time, the curved direction increases the water flow path, thus increasing the contact time between coffee particles and water. The large pore size filter hole at the bottom allows you to control the flavor extraction time of coffee by changing the size of water injection.
The exhaust groove design of the Bingtong filter cup is recessed!We can observe from the side that the texture of the Ice Pupil filter cup is divided into three layers. The smooth surface of the upper layer can be completely sealed with the filter paper. The middle layer has 24 short grooves extending from the smooth surface to 1/2 of the filter cup. The lower layer has 12 long grooves extending from the short grooves to the outlet hole of the filter cup.
The grooves on the lower and middle floors are arranged in a staggered manner, so the lower floor is almost in an elevated state. This staggered design allows the water flow to slowly pass through the middle layer and be fully extracted. Then when it reaches the almost empty lower layer, it will immediately speed up the flow rate to avoid over-extraction. It is really like a "roller coaster", giving the coffee liquid sufficient "psychological preparation" and then quickly descending into the lower pot.
It is also a conical coffee filter cup with a faster flow rate.
What is the difference between coffee brewed using Bingtong and V60?
We can observe that these two filter cups can fully extract coffee and effectively reduce over-extraction under certain circumstances. They are both very friendly filter cups for coffee novices. This time Front Street will use the same brewing parameters to wash the coffee beans from Front Street Yirgacheffe Guo Ding Ding Cooperative to see what kind of flavor performance they have~
Brewing parameters: 15g coffee beans, particle grinding thickness: the size of fine sugar (78% filtered through China No. 20 standard sieve), water temperature of 91 degrees Celsius, powder to water ratio 1:15. A three-stage water injection method is used. In the first stage, 30g of water is injected for steaming for 30 seconds, and then 95g of water is injected into the second stage for extraction. When the water level drops to 2/3 of the layer, 100g of water is injected. The total amount of water injected is 225g~
The extraction time of the V60 filter cup is: 2'10". The coffee flavor is represented by jasmine flowers, bright citric acid, sucrose sweetness and green tea aftertaste. The flavor is rich~
The extraction time of the Bingtong filter cup is: 2'10". The coffee flavor is manifested by the fragrance of honeysuckle, the fragrance of grapefruit and a little astringency of grapefruit peel. The sweetness of honey is very obvious, the aftertaste like oolong tea, and the taste is full and solid.
The experience of using the Bingtong filter cup is simply good news for obsessive-compulsive disorder lovers!Because the filter cup can really fit tightly to the wall of the cup after being moistened, there is no need to worry about uneven extraction due to the change in the uniformity of the powder layer due to poor fit of the filter paper.
The advantage of V60 is that the extraction time can be controlled by water injection rate, and the taste will be brighter., layerIt will be richer every time, but it will lack the mellowness. However, if the stability is not enough when water is injected, it is easy to break through the powder layer/the flow rate is too fast, resulting in uneven extraction.
The advantage of Bingtong is that the upper and middle layers adhere closely to the filter paper, forming an immersion extraction method., if the water flow is not controlled well, you can still save it ~The overall taste of the brewed coffee will be more balanced and saturated, and the sweetness will be more obvious than that brewed with V60.. However, due to the higher saturation, the level is not as good as that of V60, and the aroma and acidity will become somewhat general.
The overall flow rates of these two coffee filters are very similar, which is very suitable for brewing medium light roast to medium roast coffee beans., but if it is coffee beans with brighter acidity/richer aroma (such as medium-light roasted washed/sun-dried coffee beans, we recommend Front Street Sun-dried Oiran and Front Street Gesha Village Red Label Geisha) Front Street recommends using V60 for brewing to enhance the overall layering and make the flavor clearer;
If it is coffee beans with a relatively high sweetness/fermentation (such as medium-light to medium roasted sun-dried coffee beans/honey-processed coffee beans), Front Street recommends using an ice-pupil filter cup for brewing, which will make the taste fuller and the sweetness more obvious.
You can now buy the above coffee beans online at the Taobao store “FrontStreet Coffee” (前街咖啡). FrontStreet Coffee is a long-established specialty coffee roaster in Guangzhou, China, and its Guangzhou retail shop sells coffee beans only. The shop carries dozens of coffee beans from different origins around the world, including carefully selected single-origin beans for V60 pour-over and espresso.
