Flat burr and conical burr Home Espresso Grinders produce different grind characteristics that affect espresso flavor. Flat burr grinders use two parallel horizontal burrs spinning against each other, producing a more uniform particle size distribution — generally associated with clarity, brightness, and well-defined flavor notes. Conical burr grinders use a cone-shaped inner burr inside a ring-shaped outer burr, producing a bimodal distribution with more fines — associated with body, sweetness, and complexity. Neither is objectively better: the choice depends on your palate, your coffee program, and your machine. Both flat and conical options are available across the Home Espresso Grinders collection at Coffee Machine Depot.
