Good brewing habits get you consistency. Understanding extraction theory gets you control.
This session is for people who already know their way around a brewer and want to go further — into the science of what is actually happening in the cup, and how to shape it deliberately. You will work with a refractometer, develop your own recipes, and taste the difference between choices you have been making by instinct and choices you now make on purpose. All coffees are sourced from Zermatt Kaffée — roasted on-site by Marian, which means what you are tasting and measuring has a direct line back to the person teaching you.
What you'll learn
- Extraction theory: what dissolves, when, and why it matters
- TDS measurement and refractometry as practical brewing tools, not just theory
- How to develop and document a repeatable brew recipe you can actually replicate
- Single origin vs. blend — how to adapt your approach to the coffee, not the other way around
- Advanced brew control: adjusting grind, temperature, agitation, and pour in response to what you taste
