Grind Sizes



At Round Boy Roasters, we use a massive Bunn shop grinder.

Our burrs (the flat grinding plate) are custom modified to use white knight coated (diamond like coating) SSP burr replacements. Suffice to say, we spared no expenditure to get the very best grinding solution we could afford to get you consistent particle size for even coffee extraction.
