Thermal Carafe



The Ratio Thermal Carafe is the perfect tool to keep your coffee hot and your kitchen elegant. Match the finish with your Ratio Eight or use it with your favorite pour over dripper.

This carafe combines function, elegance, and durability. The insulated dewar body will keep your coffee hot for up to 4 hours after brewing. The 304 stainless steel handle and 18/8 stainless steel dewar body are very resistant to corrosive coffee acids and oils. The counterweighted handle makes pouring feel natural and well-balanced.

    Ratio Porcelain Dripper

    The Ratio Dripper is a conical porcelain dripper designed to complement the Ratio Thermal Carafe or to use as a stand-alone pour over cone. The sturdy, thick ceramic walls mean the brewer is excellent for maintaining temperature stability. The outside of the dripper features a matte white finish, while the inside has a high gloss finish to prevent coffee stains.

    The base design makes it easy to use the dripper with either the Ratio Thermal Carafe for brewing larger batches, or on a mug for single-cup brewing.

    Ratio Kone by Able

    A custom-made reusable metal filter for the Ratio Eight. Ratio teamed up with Able Brewing to create this metal conical filter specifically for the Ratio Eight Coffee Machine.

    The Kone's unique design and photochemically etched holes allow the water to flow freely through the entire filter, not just out of the end. For the Ratio Eight version, the Able team added more holes to accommodate the higher brew volumes of up to 40 ounces. The holes are round on one side and square on the other - a rare design feature that helps to eliminate potential clogging.

    Made of laser-welded stainless steel in the US, the Kone allows just the right amount of oils and sediment to pass through, giving the coffee a rich flavor that is still clean, aromatic, and delightful. The mouth feel will be slightly fuller than a Chemex filter but cleaner than a typical stainless steel filter.
