Tiamo Stainless Steel K-Type Pour-Over Filter Cup Review

If you’ve ever wondered why your pour-over coffee sometimes turns out weak or overly bitter, the issue might not be your technique—but your filter. Many coffee brewers struggle with inconsistent extraction due to poorly designed filters that either restrict flow or trap too much heat. Choosing the right filter can make the difference between a flat cup and one with balanced aroma and clarity.

The Tiamo K01 and K02 stainless steel pour-over filters solve this with a three-hole base design that allows smoother, unrestricted water flow. The K01 is ideal for 1–2 cups, while the K02 is built for 3–4. Both use cake-style filters and include a drip tray and 10g coffee spoon.

What Are the Tiamo K01 and K02?

The Tiamo K01 and K02 are stainless steel pour-over coffee filters made by CAFEDETIAMO. These filters are built with a three-hole base that supports even extraction by letting brewed coffee flow freely downward. The K01 is designed for 1–2 servings using cake-type paper filters, while the K02 accommodates 3–4 servings with the same filter type. Both models come with a drip tray and a 10g coffee powder scoop.

How the Three-Hole Design Affects Brewing

The defining feature of both Tiamo filters is their three-hole bottom structure. This design ensures that water flows downward without restriction, promoting an even and stable extraction. Unlike single-hole designs that can cause channeling or uneven drawdown times, the triple outlet balances flow rate and pressure. This leads to more uniform extraction across all coffee grounds, improving clarity and body in the final cup.

Flow Rate, Extraction, and Flavor Control

One unique aspect of the Tiamo K01/K02 is how your pouring speed directly influences the flavor outcome. Faster pouring results in a lighter, more aromatic cup, as it shortens contact time and extracts fewer bitter compounds. Slower pouring increases extraction time, drawing out more body and boldness. This gives you hands-on control over whether your coffee tastes bright and tea-like or rich and full-bodied—all through technique alone. The open structure also allows air to escape and prevents the filter from sticking to the walls, even when wet.

Why Cake Filters Work Best with These Cups

Both the K01 and K02 are engineered specifically for cake-style (cupcake or flat-bottom) paper filters. These filters hold the coffee bed in a level, compact shape, which works in tandem with the three-hole base to promote even saturation and drainage. Using the recommended cake filters ensures that the coffee grounds expand properly and that water flows uniformly through the bed, maximizing extraction efficiency and minimizing over- or under-extracted pockets.

Design Details That Support Better Brewing

Beyond the three-hole base, the Tiamo filters include several functional details. The wide internal space gives coffee grounds enough room to expand without obstruction, letting trapped air escape easily. The filter doesn’t clamp down on the coffee bed, allowing for better circulation and more even wetting during the bloom phase. The stainless steel build is durable, easy to clean, and heat-resistant, maintaining stability during the brew. Even with small amounts of coffee, the design ensures a café-quality result.

Frequently Asked Questions

What’s the difference between the Tiamo K01 and K02?

The K01 is designed for brewing 1–2 cups of coffee, while the K02 is built for 3–4 cups. Both use the same three-hole design and cake-style filters, but the K02 has a larger capacity to accommodate more coffee and water.

Do I need to use a special kind of filter paper?

Yes, the Tiamo K01 and K02 are optimized for cake-type (flat-bottom) paper filters. These filters help create an even coffee bed and work with the three-hole base to ensure smooth water flow and balanced extraction.

Does pouring speed really change the taste?

Yes. Pouring water faster extracts less and highlights brighter, more acidic notes, resulting in a lighter cup. Slower pouring increases extraction time, drawing out more body, sweetness, and bold flavors. This lets you adjust flavor intensity through your technique.

Can I use these filters for small batch brewing?

Absolutely. The K01 works well for 1–2 cups, and even with small amounts of coffee, the filter’s design ensures proper airflow and extraction, producing quality results similar to café-level brewing.

Is the stainless steel material better than plastic or glass?

Stainless steel is durable, heat-resistant, and easy to clean. Unlike plastic, it won’t retain odors or degrade over time, and unlike some glass options, it won’t risk breakage. It also maintains a neutral profile, not affecting taste or temperature during brewing.

Recommended FrontStreet Coffee Beans for Pour-Over

For use with the Tiamo K01 or K02, try FrontStreet Coffee’s Ethiopia Yirgacheffe Gedeb for a bright, citrusy profile with floral and berry notes. The Ethiopia Humbera (also known as Ethiopia Humbera or Humbera) offers tropical fruit intensity—think strawberry, pineapple, and passionfruit—with low bitterness. Alternatively, the Kenya Little Tomato brings bold acidity with sweet tomato-like tang and juicy complexity. All three are excellent single-origin choices that highlight the clarity and balance the Tiamo filters are designed to achieve.
