Ratio Eight Coffee Machine

The Ratio Eight Coffee Machine is built for coffee preparation with a focus on consistent performance, practical operation, and durable construction.

Key features

• The Ratio Eight pairs a plastic-free brew path with one-button simplicity. Glass and stainless steel keep plastic out of contact with hot water and brewed coffee. Solid wood accents, a handblown glass carafe, and a durable matte finish bring warmth and character to your countertop, while dual recipe brew programs offer more flexibility in the cup. Thoughtful design, down to the last drop.

Compatibility and care

• What materials are used in the Eight Series 2?
• The Eight Series 2 features a lightweight polymer body with a stainless steel internal structure, a Tritan water tank for cold water storage, and a stainless steel, aluminum, and glass brew path once brewing begins.How much coffee can it brew at once?
• A full batch is 40 ounces (1.25 liters), ideal for 6–8 cups depending on mug size.
• You can also brew smaller batches with the same great extraction by using recipe B.What filters can I use?
• The Ratio Eight Series 2 is compatible with the same size filters as the Ratio Six, 8-12 cup flat-bottom filters with a minimum height of 5.75 inches.
• You can also use the Able reusable stainless steel basket for a paper-free option.What carafes are available?
• Choose between a double-wall stainless thermal carafe or a hand-blown borosilicate glass carafe.
• Both are designed specifically for the Eight Series 2 and also work with the Ratio Six.
• If you add the thermal carafe, you will receive both the glass and thermal.How long does a brew take?
• A full brew typically takes 8–10 minutes, depending on batch size and water temperature.Does it have a hot plate that keeps coffee hot after brewing?
• Ratio machines don’t use a hot plate.
• Hot plates tend to overheat coffee, causing bitterness and a burnt flavor over time.
• Instead, our brewers have the option to be paired with a double-wall stainless steel thermal carafe that keeps coffee hot long enough to enjoy a full pot without altering the taste.
• If you prefer a glass carafe, we recommend serving right away or transferring your brew to an insulated vessel for the best flavor and temperature.

Beautiful through and through.

• Some machines are made to be tucked away.
• This isn’t one of them.
• From the exposed glass water line to the real wood trim, the Eight S2 is a countertop sculpture and brings intentional design into plain view.

Double-wall stainless steel flat bottom filter basket.

• Crafted without plastic, the double-wall stainless steel brew basket holds heat and supports an even extraction from every angle.
• It’s clean, intentional, and built to perform.

Hand-finished solid wood walnut trim.

• Each piece of walnut trim is solid wood, hand-finished to bring out its natural character.
• It’s a warm, organic counterpoint to the machine’s precision-built form

A cast stainless steel handle worth holding.

• The optional Eight S2 thermal carafe is topped with a cast stainless steel handle—substantial, sculptural, and unexpectedly satisfying to lift.
• It's the final step in the brewing process, and it deserves to feel just as considered as the first.

Stainless steel showerhead for full extraction.

• Crafted from stainless steel, the showerhead delivers even saturation across the entire coffee bed—no hot spots, no uneven extraction.
• Just balanced, beautifully brewed coffee every time.

Two recipe options for full and half batch.

• One button, two recipes.
• A simple long press toggles between full and half batch modes, each optimized for timing, bloom, and flavor at the right scale.

Flat bottom brew basket for even extraction.

• A flat-bottom basket means a level bed, steadier flow, and more even extraction.
• In other words: better coffee, brewed more predictably.

Stainless steel water tank fill and lid.

• Pour fresh cold water into the water tank via the pristine 304 stainless steel.
• Easy to wipe clean, the stainless fill area is covered by a solid cast stainless steel lid.

Design and performance

• With improved insulation, a wider opening, and a more ergonomic handle, the upgraded optional thermal carafe keeps coffee hotter while making every pour feel smoother.
