CAFEC FLOWER DRIPPER DEEP 27 - Clear Black

By narrowing the bottom angle of the dripper to a maximum of 27 degrees, we have created a dedicated "FLOWER DRIPPER" for a single cup. You no longer need to control the extraction.

Just pour hot water into the center once to brew the "ultimate single cup". Simpler, more delicious coffee. Please enjoy.

The previously released "DEEP45" dripper was developed with the concept of creating a deep filtering layer inside the dripper by narrowing the bottom angle to 45 degrees. However, due to the 45-degree angle, a small amount of coffee grounds could not form an ideal deep filtering layer, so it was necessary to deliberately brew 3 to 7 cups to achieve the ideal deep filtering layer.
However, in response to the enthusiastic feedback from people at home and abroad for a single-cup version of DEEP, and the increasing popularity of single-cup pour-over enjoyment, we developed the "FLOWER DRIPPER DEEP 27".
It is perfect as a daily treat for yourself or as a gift for your loved ones. Enjoy the most delicious single cup.

Why 27°?
After repeated trials, we arrived at the ideal bottom angle for a single cup. It took about 5 years from conception to completion.

(1) Even with a single cup of coffee grounds, a sufficient filter layer (sediment layer of coffee powder) can be formed.
(2) CAFEC's ideal extraction speed, where the speed of pouring water from the top and the speed of extracting coffee liquid from the bottom are the same.

Brewing with DEEP 27 will bring more richness and sweetness to your coffee. It can extract the characteristics of each coffee, only extracting the pleasant taste components.

Special structure of the dripper
During the development of the FLOWER DRIPPER DEEP 27, we always considered the balance between the dripper and the paper, aiming to create a dripper that achieves the "ultimate single cup". We were able to design such a special flower-shaped dripper structure only because CAFEC has a deep understanding of coffee paper filters.

Key Point 1
Perfect rib height
Even if the bottom angle is narrowed, the brewing speed does not decrease. This is because the height of the ribs subtly changes towards the bottom hole. This ideal rib height maintains an appropriate air layer between the paper and the dripper until the end, and creates a strong osmotic pressure inside the dripper, thereby brewing delicious coffee.

Key Point 2
Optimal size of the bottom hole
Adjusting the height of the ribs inevitably changes the size of the bottom hole. However, if the bottom hole is too large, the paper will protrude too much from the dripper, and it will not be able to withstand the weight of the coffee powder and hot water in the latter half of the brewing, and the paper will easily tear. On the other hand, if the bottom hole is too small, the paper will not protrude much, the powder will clog near the bottom hole, and the brewing speed will slow down. The DEEP 27 dripper shape maintains the strength of the paper until the end and does not reduce the brewing speed. After many trials, the optimal size of the bottom hole was finally achieved.

Key Point 3
Its shape is convenient for direct brewing into the cup
DEEP 27 is the dripper for the "ultimate single cup". Therefore, during the design, we also assumed that you would brew directly into the cup. Through the curved base of the dripper, we succeeded in keeping the distance between the dripper and the cup further. Therefore, the bottom tip of the paper is less likely to be soaked in coffee, which prevents the filter paper from tearing and coffee grounds from entering the coffee.
