Espresso Science

Espresso Science is a focused technical workshop designed to help baristas better understand extraction, dialling in, and the variables that influence espresso quality. Ideal for Baristas and new coffee professionals looking to deepen their technical understanding, this course explores how grind size, dose, yield, time, and recipe adjustments impact flavour, consistency, and workflow during service. Participants will move beyond simply following recipes and begin developing the confidence to understand why espresso behaves differently throughout the day and how to respond effectively under pressure. Your team will learn how to: Understand espresso extraction and balance Dial in coffee confidently and consistently Adjust grind size with purpose Understand the relationship between dose, yield, and time Identify under and over extraction Troubleshoot inconsistent espresso shots Maintain consistency during changing service conditions Improve workflow and communication on bar By the end of the workshop, participants will feel more confident controlling espresso quality and making informed adjustments during service. The result is improved consistency in cup quality, reduced waste, stronger workflow under pressure, and greater confidence behind the espresso bar. Delivered by the North Star Coffee Academy, this course combines practical espresso training with approachable coffee science to help baristas build real understanding, not just repetition.
