Tiamo Glass Flannel Dripper for Manual Coffee Brewing

If you’ve ever tried to cut down on paper waste while making pour-over coffee, or just want a richer mouthfeel without a metal filter, you’ve probably wondered: can a fabric filter really make a difference? Many coffee enthusiasts are turning to flannel brewers—not just as a gimmick, but as a way to enhance body and clarity at the same time.

The short answer: yes. A Tiamo glass flannel brewer, using medium-fine ground coffee at around 10–12 grams per 120ml brew, can produce a clean yet full-bodied cup in just 3–5 pours. It’s reusable, washable, and transparent—so you see every stage of extraction.

What Is a Tiamo Glass Flannel Dripper?

The Tiamo glass flannel dripper is a pour-over coffee brewer made with a heat-resistant glass body and a replaceable flannel filter—specifically a blend of T-R warp and CVP weft fabric. It comes in two sizes: 240cc and 480cc, making it suitable for single or double servings. The design is minimalist, fully transparent, and aimed at manual brewers who value both sustainability and visibility during brewing.

Unlike paper filters, which absorb some coffee oils and fine particles, flannel allows more of the coffee’s natural body and aromatic compounds to pass through. The glass construction adds durability and makes the brewing process easy to observe.

How to Brew Coffee with the Tiamo Flannel Dripper

Brewing with the Tiamo flannel dripper follows a standard pour-over method with a few important adaptations for fabric filtration. Here’s the step-by-step:

• Grind your coffee to a medium-fine consistency (similar to table salt).
• Use approximately 10–12 grams of coffee for a 120ml (one-cup) brew. Adjust proportionally for larger volumes.
• Place the dampened flannel filter inside the glass dripper. (More on preparing the flannel below.)
• Add your ground coffee and start with a bloom: pour just enough hot water (just off boil) to saturate all the grounds, covering them with about 1cm of water. Let it bloom for 20–30 seconds.
• Begin your first main pour in circular motions from the center outward, letting tiny bubbles form. When the coffee bed settles slightly, continue pouring in stages—typically 3 to 5 total pours to fully extract the coffee.
• Try to maintain a steady brew ratio, commonly around 1:12 to 1:16 depending on taste preference.

The transparency of the glass lets you watch the drawdown and adjust your technique in real time. The fabric retains some fines but allows a fuller body than paper, with a cleaner cup than metal.

Caring for Your Flannel Filter

Flannel filters require proper prep and maintenance to perform well and last:

• Before first use, soak the new flannel filter in cold water, then wring it out and let it dry slightly before brewing.
• After each brew, rinse the flannel thoroughly in water only—no soap.
• To prevent oxidation and smells, store the damp flannel in water inside the refrigerator. Change the water daily.
• Never use a dry flannel filter for brewing; always wet it first with hot water and wring gently before use.

With proper care, the flannel can be reused many times, reducing waste and long-term costs compared to disposable paper filters.

Frequently Asked Questions

What grind size should I use with a Tiamo flannel dripper?

Use a medium-fine grind, roughly similar to table salt or slightly finer than what you’d use for a V60. This helps balance extraction time and flow rate through the flannel fabric.

How much coffee do I use per brew?

For a 120ml brew (single serving), use 10–12 grams of coffee. Scale up proportionally for larger brews, maintaining your preferred brew ratio, often between 1:12 and 1:16.

Do I need to rinse the flannel filter before each use?

Yes—but not with soap. Always rinse the flannel filter thoroughly in clean water after brewing, and before each new brew session. Pre-wet it with hot water and gently wring out excess moisture just before use.

How do I store the flannel filter after brewing?

Rinse it in water only, then store it damp in a container with fresh water inside the fridge. Make sure to change the water daily to prevent odors and bacterial growth.

Can I use the Tiamo flannel dripper for any coffee bean?

Yes. The flannel filter works well with most coffee types, but it particularly enhances body and clarity in single-origin coffees, especially washed or lightly roasted beans. It’s versatile enough for daily use with a range of origins and roast levels.
