How to Brew with a Tiamo Flannel Pour-Over Filter Set

If you’ve tried pour-over coffee but find paper filters altering the body or trapping too much of the coffee’s natural oils, a flannel filter might be the upgrade you need. Unlike disposable paper, flannel allows more oils and fines to pass through, creating a fuller-bodied cup—without the waste. But how do you get a clean, flavorful brew with fabric instead of paper? This guide breaks down everything you need to know using the Tiamo 480ml flannel pour-over setup.

The Tiamo flannel filter system (available in 480ml HG2226 or 240ml HG2225 sizes) is a reusable glass pour-over brewer with a cloth filter that produces a richer, fuller cup than paper. For best results, use medium-fine grind (similar to table salt), around 10–12g coffee per 120ml water, and follow a controlled blooming and pouring process to fully extract the coffee’s character.

What Is the Tiamo Flannel Pour-Over System?

The Tiamo flannel pour-over coffee maker is part of the HG2225 (240ml) and HG2226 (480ml) product lines, made with durable heat-resistant glass and a replaceable cotton flannel filter. Designed for manual pour-over brewing, it combines the clarity of pour-over with the enhanced mouthfeel that cloth filtration provides. The transparent glass body not only looks clean and modern—

These brewers fall under the “American-style” coffee category, meaning they’re built for standard drip-style brewing rather than espresso or immersion. The flannel filter is designed to be reused, making it both economical and environmentally friendly compared to single-use paper filters. With proper care, it can last for months, offering a consistent brew texture that sits between paper and metal.

Why Use a Flannel Filter Instead of Paper?

Flannel filters produce a cup with more body and retained aromatic compounds due to their porous structure. While paper filters catch most coffee oils and fine particles—resulting in a cleaner, brighter but sometimes thinner cup—flannel allows more of the coffee’s natural textures and micro-grounds through. That means a rounder mouthfeel, more complexity, and often a sweeter finish.

That said, flannel requires more attention to cleaning and maintenance to prevent off-flavors. The material is less prone to clogging than paper, but it can oxidize or retain stale aromas if not rinsed and stored properly. For coffee lovers seeking a balance between clarity and richness, flannel is a compelling middle ground.

How to Brew Coffee with the Tiamo Flannel Filter

Here’s a step-by-step guide to using the Tiamo 480ml flannel pour-over system for optimal extraction:

• Grind Size: Use a medium-fine grind, similar to table salt or slightly finer. This helps achieve proper extraction without over- or under-extracting.
• Dose: For a single serving (approx. 120ml), use 10–12g of freshly ground coffee. Adjust based on your taste preference and the full 480ml capacity.
• Preparation: Before first use, soak the new flannel filter in cold water, then wring it out gently. Rinse it thoroughly before each brew to remove any dust or residues.
• Bloom: Start by pouring a small amount of hot water (just off boil, ~93°C) to saturate all the coffee grounds. Add enough to cover the grounds with roughly 1cm of water. Let it bloom for 20–30 seconds—this releases trapped gases and primes the coffee bed.
• Pouring: After blooming, pour water in a circular motion starting from the center and moving outward. Allow the coffee bed to settle slightly between pours. Continue adding water in 3–5 total pours, maintaining even saturation across the grounds.
• Total Water: Aim for a brew ratio around 1:12 to 1:15 (e.g., 12g coffee to 144–180ml water), adjusting to taste. Total brew time should be around 2:30 to 3:30 minutes for balanced extraction.

Cleaning and Maintenance Tips

To keep your flannel filter performing well and avoid bad tastes:

• Always rinse the filter with hot water after each use to remove coffee oils and residue.
• Never let the filter dry out between uses. Store it damp in the refrigerator, submerged in water to prevent oxidation and bacterial growth.
• Change the water in the storage container daily to avoid mineral buildup or odor.
• Do not use a dry filter for brewing—it must be dampened with warm water and wrung out before each use to prevent paper-like dryness or off-notes.
