Essential answers for the perfect pour.

Dialing in whole bean coffee shouldn't feel like guesswork. Here is the exact technical baseline our head roaster uses to calibrate extraction across every roast tier.

Light roasts are denser and extract slower, requiring a finer grind size and higher water temperatures (205°F–208°F) to unlock vibrant floral notes. Dark roasts are more porous and extract rapidly, so grind slightly coarser with cooler water (195°F–200°F) to prevent harsh bitterness. Medium roasts perform best with a balanced medium-fine grind at 200°F.

Roaster Note:Pro tip: Adjust your grind in small micro-clicks rather than changing brew water temperature simultaneously.
