In-depth Explanations with Actionable Insights:
Espresso Extraction Parameters and Troubleshooting To master espresso extraction, baristas must understand the four key variables: grind size, dose, water temperature, and extraction time. A balanced espresso shot should have a sweet, rich, and complex flavor profile without bitterness or sourness.
Variable Action Outcome Grind Size Adjust grinder to a finer setting for slow extraction or coarser for faster extraction. Changes the resistance water faces, altering extraction time and taste. Dose Use a digital scale to measure coffee grounds (18-20g for a double shot). Ensures consistency and affects the strength and flavor of the espresso. Water Temperature Set the machine between 195°F and 205°F. Affects the extraction rate of different flavor compounds. Extraction Time Aim for 25-30 seconds for a double shot. Time taken for the water to ...
