CAFEC Deep 27 Abaca+ Paper Filters
Designed specifically for the CAFEC Flower Dripper Deep 27
These specialized paper filters are engineered to work with the unique 27° deep cone design of the CAFEC Deep 27 dripper. Their shape and structure maintain the ideal air layer between the dripper and filter, allowing coffee grounds to expand fully and form a deep filtering bed for balanced extraction.
The result is a cup with greater sweetness, clarity, and body—bringing out the full character of the coffee.
Each package includes 100 filters.
Why These Filters Are Different
Designed for the Deep 27 Dripper
Unlike standard cone filters, these papers are molded specifically for the narrow 27° angle of the Deep 27 dripper, ensuring proper fit and extraction.
Abaca+ Fiber Blend
CAFEC’s Abaca+ paper combines traditional wood pulp with abaca fibers, creating a filter that is strong, thin, and highly permeable for smooth water flow.
Optimized Crepe Structure
The crepe pattern is engineered with narrower spacing and lower crepe height, increasing surface area so fine coffee particles adhere evenly. This promotes stable flow and consistent extraction.
Stable Extraction Speed
The filter structure helps balance the speed of pouring and extraction, making it easier to achieve repeatable results.
Why Not Use Regular Cone Filters?
Uneven Extraction
Folding a standard cone filter creates overlapping layers inside the dripper, preventing a consistent air layer between the paper and the brewer.
Disrupted Coffee Bed
The overlapping paper can cause uneven distribution of grounds, preventing the formation of the deep sedimentary layer that the Deep 27 brewer is designed to create.
For best results, dedicated Deep 27 filters are strongly recommended.
Brewing Compatibility
Designed for use with:
Not compatible with standard V60 or Kalita-style brewers.

What Is 100% Kona Coffee?
100% Kona coffee refers to coffee grown exclusively in the Kona district of Hawai‘i Island — a small, volcanic region
along the western slopes of Hualālai and Mauna Loa. The combination of mineral-rich soil, afternoon cloud cover, and gentle trade winds produces one of the world’s most distinctive coffee terroirs.
To be labeled “100% Kona Coffee,” every bean must be grown within the Kona district and meet strict Hawai‘i grading quality standards. Kona coffee can be made from different arabica varieties, but Kona Typica — a heirloom lineage — remains the region’s most common and traditional cultivar.

About Kona Coffee
-
Kona coffee grows on the volcanic slopes of Hawai‘i Island, where mineral-rich soil, afternoon cloud cover, and slow cherry maturation create a naturally sweet and balanced cup. Our Kona Classic Medium is sourced from high-elevation farms and hand-harvested for clarity, smoothness, and elegant sweetness.
-
Yes — this roast is Authentic Kona coffee made exclusively from North Kona district-grown coffees, never blended. Our Kona coffees comes from small farms at the highest altitudes in the region.
-
Medium roasts highlight Kona’s signature profile: gentle sweetness, soft citrus, toasted almond, and milk chocolate. The result is a balanced, approachable cup ideal for everyday brewing.
-
This coffee shines in pour-over, drip, and French press. Use filtered water just off the boil and a medium grind for maximum clarity and sweetness. If you are looking for a Hawaiian coffee for espresso use we recommend our Hawai‘i Island Blend
-
Kona is the highest labor cost coffee region in the world. Wages for farm workers here are 15-20x higher than almost all other coffee producing countries. Limited and expensive land, hand-picking, and high production costs create a naturally small supply each year — especially from high-elevation farms like those we partner with.

Coffees
-
Our commitment to you is to serve exceptional, fresh-roasted coffees. And part of being exceptional means roasting before the flavors inherent in the green bean begin to fade, which happens over time.
Like apples and pumpkins, coffee is a seasonal agricultural product and each country has a different harvesting cycle in which coffees are at their peak. If we were to insist on serving a single origin all year long, the flavors in that coffee would be noticeably better one half of the year over the other. So the reason you no longer see that coffee you loved is because the optimal season has passed. For more on seasonality in coffees, see this blog post here.
-
Hopefully so. If it was a popular product or we receive customer requests, we will make every attempt to bring it back. However, please note that coffees from a certain producer may not taste the same year after year.
If you loved a coffee and no longer see it listed, shoot us an email and ask us what is similar. We’d be happy to provide a personal recommendation.

We aim for balance and completeness along with differentiation and distinction. You shouldn't need to be a professional coffee taster to tell the coffees a part, so, when we’re selecting coffees, we want them to be distinct from each other.
We avoid ”one-trick pony” type coffees, such as Ethiopians with great aroma but no body or acidity, or coffees with good aroma and acidity but lacking sweetness. These elements, which are often reflections of the growing conditions, are harmonized through good roasting.
And, obviously, defects — even subtle defects — influence our selection. Since we live and work at origin, we’re sensitive to coffee defects like “past crop”, pulpy, and naturals that border on over-ferment. With naturals, we’ll only carry these when great examples are available.
-
Our perspective on roasting is similar: we seek balance and distinction. To expect that a coffee is “best” when roasted to some pre-determined degree (i.e. only light roasting or only dark roasting) is analogous to thinking that each person would look best in the same outfit, or each coffee should be grown in the same way. We believe it’s our job to discover the roast degree which best highlights outstanding qualities in each coffee.
