Thanks to the bottom angle of 27°, we were able to bring you FLOWER DRIPPER DEEP 27 for one cup. No more difficulty in controlling the water flow. You can just continue to pour water to the center, and enjoy your “best cup”.

Easy to brew and much more delicious coffee with DEEP 27!

DEEP 27 Development Story
DEEP 45 was a dripper developed from the idea of forming a deep filtering layer by narrowing the bottom angle to 45°. However, due to its’ angle of 45°, it was ideal for 3~7 cups and not the ideal deep filtering layer for one cup.

However, we received many passionate requests from Japan and overseas coffee lovers wanting a DEEP dripper for single cup. Therefore, in order to spread joy among our coffee lovers who enjoy single cup of coffee, we researched and developed the dripper “DEEP 27”.

We hope that you can enjoy your best cup with DEEP 27, as a reward for yourself or to share with your someone special.

Why 27˚?
After trial and error, we arrived at the ideal bottom angle for one cup.

It took about 5 years from idea development to its completion.

(1) Even a single cup of coffee grounds can form a sufficient filtering layer (the sedimentary layer of coffee powder).

(2) CAFEC’s ideal extracting speed, the speed of pouring water from the top and the speed of extracting coffee liquid from the bottom are the same.

As a result of our research, we got the ideal angle of 27° for one cup.

The taste of coffee brewed with DEEP 27
Brewing with DEEP 27 will bring much more richness and sweetness to your coffee. It can pull out the characteristics of each coffee and extract only the pleasant taste components.

Special structure of the dripper
In the development process of the FLOWER DRIPPER DEEP 27, we have always considered the dripper and paper balance and pursued the dripper that fulfills “the ultimate cup”. We were able to design such a special flower dripper structure, only because CAFEC has a thorough knowledge of coffee paper filter

Perfect rib height

Even if the bottom angle is narrowed, the brewing speed will not drop. This is because the height of the ribs is subtly changed towards the bottom hole. This ideal rib height maintains an appropriate air layer between the paper and the dripper until the end, and generate a firm osmotic pressure inside the dripper to brew a delicious coffee.

The best size for the bottom hole

Adjusting the height of the rib inevitably changes the size of the bottom hole. However, if the bottom hole is too big, the paper will protrude too much from the dripper, and it will not be able to withstand the weight of coffee powder with hot water in the latter half of the brewing, and the paper may tear easily. On the other hand, if the bottom hole is too small, the paper will not protrude much and the powder will clog near the bottom hole, and slow down the brewing speed.

DEEP 27 dripper shape can hold the strength of paper until the end and not reduce the brewing speed. After many trials, finally we reached the best size for the bottom hole.

The shape makes it easy to brew directly into the cup

DEEP 27 is a dripper for “the ultimate cup”. Therefore, when designing, we also assumed that you will brew directly into the cup. With the curve-shaped pedestal of the dripper, we succeeded in keeping the distance between the dripper and the cup a little farther.

Therefore, the bottom tip of the paper is less likely to get soaked in coffee, preventing tearing of the paper filter and coffee powder getting into the coffee.
