Varia FLO Fast Filter Papers 21GSM – for a clear, light cup
Once you place the paper in and give it a quick rinse, the water flows through fast. The thin 21 GSM fiber barely holds it back – the coffee stays bright, clear and light on the palate. That's exactly what the Fast paper is made for.
Coffee Coaching Club is the exclusive Swiss importer of Varia.
What makes the Fast papers special
The Fast papers are made from FSC-certified Japanese pulp, are neutral in taste and smell, and add nothing of their own to the coffee. At 21 GSM, they're deliberately thin: the water flows through faster, contact time is shorter, and the cup becomes brighter and lighter. The wave-shaped design creates an even water flow and stable temperature in the filter bed. They fit the Varia FLO Dripper and other flat-bottom drippers. One pack contains 100 filters.

Fast or Slow?
The Fast paper (21 GSM) lets the water flow through quickly and emphasizes a bright, clear cup. If you like more body and a richer cup, you reach for the thicker Slow paper (50 GSM), which slows down the flow. With the FLO system, you can discover and compare both.
What goes with it
The papers belong to the Varia FLO Dripper and pair with the FLO Glass Server from the same collection. For dosing, a scale from Normcore or Acaia, plus a grinder from the Coffee Grinders collection and beans from our Coffee Roastery.

Frequently Asked Questions
What's the difference between Fast and Slow?
The Fast paper, at 21 GSM, is thinner and lets the water through faster, resulting in a brighter, clearer cup. The Slow paper at 50 GSM slows down the flow for more body.
What size do I need?
That depends on your dripper. For the FLO Dripper and common flat-bottom drippers, the papers come in 55 × 48 mm and 85 × 48 mm.
Do the papers only fit the FLO Dripper?
No. They also fit other flat-bottom drippers, such as Kalita-Wave style.
How many filters are in one pack?
100 filters per pack.
Roastery tip
The Fast paper pairs well with lighter roasts, where you want clarity and fruit to stand out. A quick rinse of the paper before brewing removes any paper taste and warms the dripper. Our Nutty Delight comes through clear and nutty in the cup this way. That's our recommendation, one among many.
