Inspired by James Hoffmann "Understanding Espresso" YouTube series - This podcast episode is the first in a six-part series focusing on individual variables in espresso brewing. This episode specifically examines the dose, which refers to the amount of ground coffee used in a portafilter. The primary goal is to explain how the dose affects extraction and overall espresso quality. The series aims to give viewers a better understanding of why certain decisions are made during the espresso "dialing in" process.
