Stop treating light roasts like traditional espresso beans. Their dense cellular structure demands a complete rethink of extraction ratios and puck preparation to avoid the dreaded sour-bitter trap. By shifting your focus from grind time to yield ratio, you can finally unlock the hidden floral and juicy notes that usually get lost in a standard pull.

The long-held belief that boiling water is mandatory for light roasts is under fire. Controlled experiments show that extraction yields remain virtually identical between 85°C and 100°C, but the sensory impact is night and day. Discover why your pursuit of higher temperatures might actually be ruining your coffee's flavor profile.
