What does a flat bottom change compared to a cone filter?
A flat bottom spreads the coffee bed into a layer of even depth, while a cone tapers towards the bottom. Everything else follows from that geometry. In a flat bed there is roughly the same amount of coffee across the whole surface, every particle spends a similar time in contact with water, and the result reads as more balanced. Uneven pouring shows up less. In a cone the bed gathers towards the tip, so water passes through a deeper layer in the middle. That emphasises clarity and individual notes, but it reacts more sharply to grind size and pouring pace. The filter matters in practice: a flat bottom needs flat bottom filters, a cone needs cone filters, and the two are not interchangeable. The Graycano Coin is an insert made from food-safe premium silicone with seven outlet holes. It docks into the Lava Ribs of the Graycano Dripper and switches it to flat bottom filters for one to two cups.
Cone and flat bottom compared
The table puts the Graycano Dripper with the Coin fitted next to the same dripper without it. The comparison covers what the shape does to the coffee bed.
| Shape | Bed geometry | Flow | Filter type | Error tolerance |
|---|---|---|---|---|
| Flat bottom (with Graycano Coin) | even depth | even across the surface | flat bottom filters | high |
| Cone (Graycano Dripper alone) | tapering to the tip | concentrated towards the centre | size 1 cone filters | medium |
