The Science Behind SNAP

Product Overview

Snap's 10-channel curvature helps the paper filter stay evenly supported against the wall by raising the capillary adhesion of the filter paper, reducing bypass considerably. The sealed channels then act like exhaust vents, giving CO₂ and displaced air a clean route out, and letting you apply repeatable snaps during the brew.

These snaps help release trapped gas, saturate the coffee particles, and settle the bed. The force of the spring is tuned through computational fluid dynamics to evenly saturate the coffee particles with water whilst not creating fines migration and clogging. The result is a brewer that keeps the ritual of pour-over while reducing the volatility that normally comes from blooming, uneven wetting, and channeling.

Why the bloom is faster

Fresh coffee releases CO₂ rapidly when hot water reaches the grounds. If that gas remains trapped in the coffee bed or behind the paper, it slows wetting and can push water toward easier paths. Snap gives that gas a cleaner escape route through the side-channel geometry.

Because CO₂ can leave faster, the bloom can finish faster and more evenly. This does not mean rushing the brew. It means the coffee reaches a fully wetted state sooner, with fewer dry pockets and less gas blocking water from entering the coffee structure.

How the snaps improve saturation

The SNAP sequence adds a short, repeatable mechanical impulse to the brewer. That impulse helps detach gas bubbles from the surface of coffee particles, breaks small air pockets inside the slurry, and encourages water to replace gas around and between the particles.

In practice, the bloom snaps help finish saturation early. The final snaps help settle the bed and clear remaining gas before drawdown finishes. The goal is not random agitation. The goal is repeatable particle–water contact.

How it works

The stages of a snap

Simplified scientific explanation

In a coffee bed, water flow depends on bed permeability, bed thickness, water viscosity, and pressure difference. Trapped CO₂ reduces the effective permeability of the bed because gas occupies pore space that water should use. When resistance becomes uneven, water tends to move through easier paths instead of wetting the coffee uniformly.

Snap addresses this through passive geometry and active snapping. The continuous side channels give displaced air and CO₂ a path out while the wall geometry keeps the wet paper supported. The snaps apply a short mechanical impulse that helps detach bubbles from particle surfaces and allows water to replace gas in the slurry.

This promotes more uniform particle saturation by accelerating the replacement of gas with liquid at the particle surface and within the interstitial pore network. Because the mechanical input is delivered as a short impulse rather than continuous agitation, it increases transient fluid movement without substantially restructuring the coffee bed. This limits the advective transport of fines toward narrower pore throats, where they can accumulate, reduce local permeability, and create progressively larger pressure gradients across the bed. Because fines have a much lower settling velocity than larger particles, they remain suspended in the moving liquid for longer and are therefore more susceptible to being transported with the flow, while larger particles resettle more rapidly and largely retain the bed structure. The result is a more stable hydraulic structure, with fewer localised restrictions developing as extraction progresses.

The practical effect is better early wetting, faster bloom completion, improved particle saturation, and a more uniform bed before draw-down finishes.
