Ever wonder why some espressos taste harsh and bitter while others feel smooth and balanced? The truth is, there’s no universal espresso blueprint—but over the decades, a set of widely accepted parameters have emerged, largely thanks to the work of Dr. Ernesto Illy, grandfather of Andrea Illy, co-author of Espresso Coffee. These early efforts helped lay the foundation for consistency in espresso production, even as debates continue over how rigid those standards should be.
