A flat-bottom dripper that keeps more of your pour moving through the coffee bed instead of around it
The Tri-Spin CT Flat Dripper from DragonFly Design Center is a new bone china flat-bottom pour over dripper built to close that gap. It starts from the CT62 conical dripper and rebuilds it around a flat bottom, with a grooved inner wall and DragonFly's Tri-Spin hollowed base.
How the Tri-Spin CT Manages Flow
The inner wall is a flat surface cut with 12 long grooves and 12 short grooves. The filter paper adheres to a larger area of the wall, so there is less room for water to bypass the bed and more of each pour passes through the grounds.
The grooves still leave the water somewhere to go. They act as flow guides and pressure relief channels, which keeps the drawdown smooth and the extraction even across the bed. The result is a more concentrated cup with clearer layering of flavor.
At the base, the Tri-Spin hollowed design spreads the water's exit points instead of concentrating them in the center. This reduces the risk of the middle clogging and helps water move through the whole bed. It matters most with larger doses, where localized over-extraction is more likely.
DragonFly developed the CT Flat with competition brewing in mind, where a stable, repeatable extraction counts for more than speed.

The Shanwen Jia Exterior
The outer wall carries the Shanwen Jia (山文甲) pattern first used on the CT62. Shanwen Jia, also known as Shanwen Armor, is a Tang Dynasty armor recognized by its repeating mountain pattern. On the dripper, that pattern wraps the outer wall as a continuous geometric repeat.
The exterior is the link between the two brewers. The CT62 pairs it with a conical interior, and the Tri-Spin CT pairs it with a flat bed and a grooved wall.

Product Details
Brewing with the Transit Base or Bamboo Flat Dripper Holder (Purchase separately)
Paired with the DragonFly Flat-Bottom Switch Base, the dripper brews two ways. With the switch open, it runs as a flat-bottom pour over and gives a clean, filter-style cup. With the switch closed, water stays in contact with the grounds until you open it, which gives a fuller, immersion-style cup.
Immersion is a forgiving starting point while your pour technique is still developing. The open setting gives experienced brewers direct control over pour rhythm and timing. For a setup over a server, it also fits the DragonFly Flat-Bottom Dripper Stand.
You can also choose to brew with a Bamboo Flat Dripper Holder – using it as a traditional pourover dripper.
It holds 255ml, brews 1 to 2 servings, and takes foldable flat-bottom filter paper or 185 flat-bottom paper filters.
The Groove Structure and Tri-Spin Base
• Groove structure: Twelve long and twelve short grooves on a flat inner wall let the filter sit closer to the wall while still guiding flow and relieving pressure.
• Tri-Spin hollowed base: Disperses the outflow instead of concentrating it in the center, which reduces clogging at larger doses.
• New bone china body: Heat resistant to 120°C (248°F). Safe for dishwashers, microwave ovens, and dish dryers.

Colors of actual products might show up slightly different than in the product photos. This is due to the various settings of monitors. Every monitor or mobile display has a different capability to display colors, and every individual may see these colors differently. In addition, lighting conditions at the time the photo was taken can also affect an image's color.
Products that have a shimmering coating will also show differently under different lighting setup. Colors might appear different even under a fluorescent light or a warmer shade bulb.
