If your extraction is your art, the Sibarist FLAT 2 filter is the tool that guarantees you perfection. It represents the next generation of the Sibarist FLAT concept, redesigned to offer a pour-over experience with true Zero-Bypass.

Designed for large flat-bottom drippers (e.g., Kalita Wave 185, Fellow Stagg [size M/L], and similar brewers).

 

🌟 Zero-Bypass Innovation for Extreme Precision

The FLAT 2 is the culmination of Sibarist's research to eliminate the variables that compromise your cup.

  • 100% Zero-Bypass: Thanks to a completely new design and a structure that perfectly adheres to the walls of the dripper, the filter eliminates air channels along the sides. This ensures that the water interacts only with the coffee bed.

  • Goodbye to Clogging: Forget about coffee particle trapping in wavy or grooved surfaces. The flat bottom structure ensures uniform and controlled extraction from the first to the last gram.

  • Total Repeatability: The sealed flat-bed structure drastically increases the uniformity and repeatability of your results. Get the same exceptional cup every single time.

  • Plug-and-Play Design: Enhances your workflow efficiency with a simple design to insert and use, speeding up preparation times without sacrificing quality.

 

⚡ FAST Technology for Optimal Flow

The heart of FLAT 2 filter performance is the renowned FAST Specialty Coffee Filter technology:

  • Controlled Speed: Allows fast and even drainage (fast drawdown) even without the need for side air channels. This lets you grind finer, optimizing extraction without the risk of bitter over-extraction.

  • Balanced Extraction: Ensures controlled and silky extractions, enhancing the clarity and aromatic balance of your specialty coffee.

 

🌍 Ethical and Professional Commitment

Sibarist FLAT 2 are built for excellence, with an eye on sustainability:

  • Source Materials: Made from 100% organic cellulose and produced in Spain, Barcelona.

  • Sealed Packaging: The package is sealed for freshness, protecting the filters from dust, moisture, and external odors.

  • Certified Sustainability: Packaging made from sustainable FSC certified paper.

The FLAT 2 is designed for baristas, competition brewers, and enthusiasts who accept no compromises on consistency, efficiency, and precision.

GuideHow to choose
Nitrogen & vacuum sealing
Every pack is sealed in a protective atmosphere — first vacuum, then nitrogen — to remove oxygen. Unopened, the coffee stays fresh for up to about 2 months after roasting. Shelf life depends a lot on temperature and season: a little less in summer, a little more in winter.
Roast profile
We roast in two profiles, depending on your brewing method:
  • Light — great for V60/Aeropress, for those who want brighter acidity and lots of aromatics. Recommended for all pressure-free methods (filter, Aeropress and similar).
  • Medium — great for espresso/Moka, for those who want a more intense flavour with a hint of bitterness. Recommended for espresso and Moka.
Grind
Any grind works, as long as it suits your method. With us you can choose whole beans, or pre-ground for Moka or for filter.
Shelf life
For the best taste, enjoy it within 10–45 days of roasting (60 at most). The roast date is always printed on the label.

More FAQ

Will these filters fit my Kalita Wave 185 or Fellow Stagg dripper?
Yes, Sibarist FLAT 2 filters are specifically designed to fit large flat-bottom drippers like the Kalita Wave 185 and Fellow Stagg size M/L. Their shape perfectly adheres to the dripper walls, ensuring zero bypass and precise extraction. If your dripper matches these specs, these filters will fit reliably and improve your pour-over consistency.
Can I use these filters with smaller or non-flat bottom drippers?
These filters are optimized for large flat-bottom brewers and may not fit or perform well with smaller or conical drippers. Their design ensures zero bypass only when fitting snugly against wide flat surfaces. Using them in incompatible drippers might cause leakage or uneven extraction. For best results, use only with recommended drippers like Kalita Wave 185 or Fellow Stagg M/L.
How does the Zero-Bypass design improve my coffee extraction?
The Zero-Bypass design eliminates air channels along the dripper’s sides by perfectly sealing the filter against the walls. This forces water to interact solely with the coffee bed, preventing uneven flow or channeling. As a result, you get a more uniform extraction with balanced flavor and clarity in every cup, improving repeatability and precision.
What are these filters made of and are they eco-friendly?
Sibarist FLAT 2 filters are made from 100% organic cellulose sourced and produced in Barcelona, Spain. They come in FSC-certified sustainable paper packaging, ensuring environmental responsibility. The filters are biodegradable and free from synthetic additives, making them a great eco-conscious choice for specialty coffee brewing.
How do I properly use and store these filters to maintain their performance?
Use these filters by placing them flat in your compatible dripper, ensuring a snug fit against the walls for zero bypass. Avoid folding or damaging the filter edges. Store them in their sealed packaging until use to protect from moisture, dust, or odors that could affect taste. Keep them in a cool, dry place away from strong smells.
Will these filters clog or slow down my brew time compared to traditional filters?
No, the FAST Specialty Coffee Filter technology enables fast, even drainage without the need for side air channels. This design allows you to grind finer without clogging or over-extraction risks. You’ll notice a smooth flow and balanced extraction speed, making your brewing more efficient without sacrificing control.
What is the quantity per pack and how fresh are these filters when they arrive?
Each pack contains 25 Sibarist FLAT 2 filters, sealed to preserve freshness and protect against dust, moisture, and odors. The sealed packaging ensures you receive filters in optimal condition, ready to deliver consistent results right out of the box. Keep them sealed until use to maintain quality.
