The Ratio Four coffee machine brings Ratio's signature precision brewing to a compact, counter-friendly footprint — every cup at the exact temperature your coffee deserves.
Ratio Four Coffee Machine — Precision Pour-Over in a Compact Design
Built to SCAA Golden Cup standards, the Ratio Four heats water to the precise 195–205°F brewing range and delivers a slow, even saturation pour that unlocks the full flavor of your beans. Its compact form factor makes it ideal for smaller kitchens, home offices, or anyone who wants Ratio quality without the Eight's larger footprint. Like all Ratio machines, it pairs beautifully with the Able Basket reusable filter for a paper-free setup.
Brewing Notes
Technical Note: For best results, use freshly roasted coffee ground to a medium consistency. The Ratio Four's bloom phase gives gases time to escape before the full brew — critical for even extraction and sweetness. Freshness matters: beans roasted within 2–4 weeks will reward you with noticeably more complexity in the cup.
Built for the Detail-Oriented Brewer
Pair the Ratio Four with coffees that respond to precise temperature control. Our Colombia Single Origin is a natural match — clean and sweet with the kind of stone fruit brightness that only shows up in a properly brewed cup. Add our Kenya Single Origin for a blackcurrant-forward experience that becomes extraordinary at the right temperature.
