Barista Training Workbook: Espresso Extraction, Milk Steaming, and Latte Art Technique

The margin between a technically correct espresso and one that actually tastes good is narrow and reproducible. Dose weight accurate to a tenth of a gram, tamp pressure consistent enough not to vary extraction, grind adjusted in response to shot time and taste — these are skills built through deliberate procedure, not through pulling shots at random and hoping for improvement. A systematic approach to each variable, practiced with intention, produces results that are both better and repeatable. By the end of this course you will be able to dose, distribute, and tamp a coffee puck following a documented procedure, adjust grind size in response to shot time and taste evaluation, steam and texture milk to appropriate temperature and consistency for flat whites, lattes, and cappuccinos, and pour a heart and a rosetta using correct jug position and wrist movement. What you will learn: - Machine setup: group head temperature, boiler pressure, and daily cleaning routines - Dosing and distribution: weight targets, distribution technique, and why puck preparation affects extraction - Tamping procedure: level tamp, pressure consistency, and how channeling happens and how to prevent it - Shot evaluation: using shot time, volume, and taste to diagnose and adjust grind - Milk steaming: purging the steam wand, tip submersion depth, and the vortex technique for microfoam - Texture targets by drink: flat white silk, latte foam depth, cappuccino dry vs. wet foam - Latte art fundamentals: jug-to-cup distance, pour rate, and the rocking motion for pattern creation - Heart and rosetta pouring: step-by-step written pattern description and common failure corrections Each module presents the procedure in numbered written steps with an accompanying checklist for use during supervised practice. Worked examples trace the diagnosis of an under-extracted shot through grind adjustment and re-evaluation, and the correction of a steamed milk batch that developed large bubbles. Troubleshooting tables cover the most common espresso and milk problems with root-cause analysis. This course is designed for barista trainees, hospitality students, and coffee professionals preparing for or engaged in supervised bar training. Suitable for anyone new to espresso equipment. This course is educational; developing genuine espresso and milk technique requires extensive supervised hands-on practice on professional equipment.
