Savina 's filter cup, runner-up of the 2023 Athens World Coffee Brewing Championship
Graycano Dripper is the first coffee dripper made from cast-in-place aluminum with a high-tech coating
The filter takes advantage of aluminum's low heat capacity - quickly reaching high temperatures and staying hot throughout the brewing process - while not allowing your coffee to come into direct contact with the metal, keeping the aroma and flavor "pure and unaffected." Under this thermal dynamics, the fruity and floral aromas of the coffee are strongly highlighted.
Additionally, the Graycano Dripper’s double-walled cylinder helps retain heat within the conical inner wall, slowing heat loss to the environment and thus maintaining temperature stability during the brewing process. The distance between the walls creates air pockets that trap the heat of the brewing coffee and maintain the temperature of the filter cup and grounds bed.
The unique V-shaped structure (lava ribs) has several functions and is carefully designed to combine to achieve a perfect extraction.
The spiral shape and position of the ribs help enhance the natural flow of water. Unlike many drippers, the Graycano Dripper's construction is designed to break up any air and water channels that may form. Water can flow freely between the gaps in the V-shape and destroy these channels. Creates an evenly moist coffee bed - ensuring even extraction.
An equally important feature is the natural water agitation of the V shape. Through the asymmetrical ribs, the water agitates itself, and this agitation makes the flavor and taste of the coffee more intense.
Graycano Dripper Unique design for better coffee extraction, enhanced sweetness and more fruity coffee flavor.

High-tech coating: food safe. Insulating the aluminum from the coffee, transferring heat but keeping the flavor of your coffee pure and untouched.

Lava Rib: Rapid water flow and constant agitation of the powder bed for a balanced extraction.

Double layer: Isolates the conical inner wall to slow down heat loss and ensure temperature consistency.

Air Pockets: Capture the heat of the brewing coffee and maintain the temperature of the coffee bed.

Cupping results: The fruity and floral aromas of the coffee were enhanced. A pure and balanced wine with a sweeter, brighter aroma.
