The gap between pulling a good shot and pulling the same good shot twenty times in a row is where most baristas quietly stall. This session addresses that gap directly.
You will work through extraction theory in depth, develop a sensory-led approach to dialling in, and practise the kind of workflow that holds up under real pressure. The milk science section alone tends to change how people think about texture. All coffees used are from Zermatt Kaffée — Marian's own roastery — so the feedback loop between what you are tasting and the decisions behind the roast is unusually short.
What you'll learn
- Advanced espresso extraction theory: under-extraction, over-extraction, and channelling — how to identify and correct each
- Sensory-led dialling: using taste, not just numbers, to make the right adjustments
- Workflow under pressure: speed, consistency, and how to recover when things go wrong
- Producing consistent results without losing quality control as pace increases
- Milk science in depth: fat content, protein structure, temperature thresholds, and how they determine texture and flavour
