Wave B3 Filter Paper

At Reserved, we get a little nerdy about our filter papers and for good reason.
They’re one of the most decisive variables in any brew. Choose the right paper and you unlock consistency, clarity, and elevated extraction. Choose the wrong one… and even the best coffee and technique can fall short.

That’s why we trust Sibarist, a name synonymous with top-tier filtration. Their papers are a favourite among Brewers Cup and AeroPress competitors worldwide including our own Founder, Yajur Gambhir who used them in Mumbai Prelims of National Brewers Cup 2025.

Filter papers are the quiet hero of repeatability.
They’re what dictate drawdown behaviour, filtration precision, and ultimately how clean and expressive your cup becomes. While many brewers obsess over grinders, burr geometry, pouring styles, agitation, and water temperature, the filter material itself is often overlooked — despite being one of the strongest levers in extraction control.

Sibarist’s iconic FAST series is known for its rapid drawdown, resulting in ultra-high clarity and a silky mouthfeel — a favourite for bright, crisp cups.

But the newer B3 filter, developed with World Brewers Cup Champion Matt Winton, takes things a step further.
The unique B3 fibre structure enhances rigidity and maintains the Wave filter shape impeccably, enabling consistently high extractions with stunning clarity. It’s a filter engineered for balance, sweetness, and a more developed flavour profile than what FAST papers typically yield.

Our recommendation:
If you’re brewing coffees that shine with sweetness, depth, and articulate clarity, the Sibarist B3 is our top choice. It’s the most underrated yet impactful upgrade you can make to your pour-over setup.
