Need to Know
The Ratio Four Series 2 is the answer to a question specialty coffee has been asking for years: why can't automatic drip taste as good as manual pour-over? Now it does. This compact brewer delivers the precision blooming, water distribution, and temperature control of a skilled barista — but at the push of a button. Brew a single cup with your own V60, pull 22 ounces into a thermos for the road, or dial in a half-batch for two. The external water tank means it fits anywhere: kitchen counter, Airbnb, camper van, coffee corner. No plumbing. No compromise.
Key Features
- Redesigned showerhead (Series 2) — Water distributes evenly across the coffee bed for balanced extraction every time, no stirring required
- Pulse brewing — Mimics the rhythm of a manual pour-over, with updated timing for higher end-brew temperature and richer flavor
- Flexible batch sizes — Single cup, half-batch (up to 22oz), or use your own dripper for V60-style brewing
- Quieter pump — Whisper-quiet operation so your morning routine stays calm
- Improved filter basket — Longer handle, smoother rails, no more accidental brew cycles when inserting or removing
- Adjusted button sensitivity — Confident, intentional starts every time
- External water reservoir — No plumbing, no fixed location — place it wherever you need great coffee
- Built to last and repair — Five-year warranty, user-serviceable design, quality materials that keep machines out of landfills
Ideal For
Coffee drinkers who want pour-over quality without the ritual. Households that need one perfect cup in the morning or a full thermos to go. Airbnb hosts who want to offer guests specialty coffee without training them on technique. Anyone tired of pod waste, bad drip coffee, or machines that can't be fixed. The Ratio Four works for beginners who want better coffee immediately and enthusiasts who appreciate precision engineering. If you care about what's in your cup and want a machine that will still be brewing great coffee a decade from now, this is it.
