Sibarist Wave Specialty Flat-Bottom Filters (Sizes S & M | FAST & B3 Versions) | The World Champions' Choice for Ultimate Extraction, 100 pcs
Unlock the Full Potential of Flat-Bottom Drippers: The Sibarist Wave Flagship Filter Range Have you ever struggled with clogged filters, slow drawdown or over-extraction when using a flat-bottom (wave) dripper? Sibarist, from Barcelona, Spain, brings a revolution to flat-bottom brewing! Now upgraded with two sizes and two versions, whether you're after pristine clarity and brightness or the full sweetness of high extraction, you'll find your perfect match.
💡 Buying Guide: Two Core Versions to Suit Your Flavour Preference
Sibarist's exclusive FAST fibre technology increases flow rate by approx. 15% to 40%. It significantly reduces extraction resistance, helping you say goodbye to bitterness and woody notes, and amplifies the beans' clarity, bright acidity and refined complexity.
Sibarist's latest technology, created for the most even extraction possible. While maintaining an excellent flow rate, it noticeably increases extraction yield and body, delivering a silkier mouthfeel and bursting, juicy sweetness.
📐 Two Sizes: A Perfect Fit for Popular Drippers
- Size S (1 to 2 cups): A perfect fit for Kalita Wave 155, Orea V3/V4 (Small), April Brewer (Small), Fellow Stagg X and other small flat-bottom drippers.
- Size M (2 to 4 cups): A perfect fit for Kalita Wave 185, Orea V3/V4 (Large), April Brewer (Large) and other medium and large flat-bottom drippers.
✨ Key Product Highlights
- 100% organic, zero papery taste: Made from premium natural materials including abaca (Manila hemp), European pine fibre and plant-based PLA, for pure, flawless coffee flavour.
- Special wave design: Reduces contact between the filter and the dripper walls, improving airflow and effectively reducing bypass, so every drop of water passes evenly through the coffee bed.
- The world champions' secret weapon: Sibarist filters are a frequent sight at the World Brewers Cup (WBrC) and an essential tool for world champions such as Martin Wölfl in pushing the limits of flavour.
- Precision-made in Spain: Developed and made in Barcelona with the specialty coffee world's relentless attention to detail and sustainability.

☕ Pro Brewing Tips
1. Adjusting Grind Size and Water Temperature
- With the FAST version: Because it flows so quickly, we recommend grinding a little finer than usual and boldly trying a higher water temperature. This greatly improves extraction efficiency, adding sweetness and body without easily producing unpleasant bitterness.
- With the B3 version: Keep your usual specialty coffee grind size; its special fibre structure will bring out higher extraction and fuller body for you.
2. No Need to Pre-Rinse
The high-purity material means these filters have almost no papery taste. You can skip the pre-rinse and add your coffee straight away, saving time and water!
