Interactive Coffee Tools & Simulators

Interactive Coffee Tools & Simulators

Coffee is easiest to understand when you can get your hands on it. That's why we've packed our knowledge into interactive tools: move the grind size, ratio, pressure or lever and see straight away what happens inside the machine and in the cup. Every tool has examples you can click and tells you in one sentence what your result means.

We dose by weight and ratio, not by the clock. The tools show you the direction; your cup decides: if you like it, you're right.

Seventeen tools, four kinds. Next to its topic, every card says what the tool does:
  • calculatesnumbers as a result that change with your inputs.
  • showsan animation you can switch through, with no numbers as a result.
  • findspicks out something from our range that fits you.
  • explainsa knowledge page to read, not a tool with settings.
All numbers from the calculating tools are model values, not measurements: estimated and computed, not measured on your machine. The finding tools suggest what fits based on our experience from the showroom and courses. That's an assessment, not a test verdict. Every tool page says what its model is based on.

Which machine suits you?

By look, kitchen and daily routine instead of spec sheet: a few questions, photos of real kitchen setups, and for every machine one sentence on who it's a good fit for.

Which grinder suits you?

Body or clarity, a new bean every day or your favourite bean in the hopper: five questions, and you'll see which grinders fit you and your machine.

Espressocalculates

Espresso Extraction

Dial in by weight and ratio, not by the clock: we grind fine, start at 14.5 g and work our way up, usually to 17 g, at a ratio below 1:2. You see when the cup turns more sour, balanced or more bitter. With examples like “tastes sour” and the extraction yield (EY) in percent. The TDS calculation lives in the Filter Coffee Simulator.

Espressocalculates

Pressure Profiling Simulator

See how pre-infusion, peak pressure and a declining profile change the water's path through the puck, and where channels form.

Try it
Espressocalculates

Puck Prep & Channeling

See how distribution (WDT), tamping and grind size prevent channels, and why an uneven puck tastes sour and bitter at the same time.

Espressofinds

Puck Prep Workshop

Put your setup together: dosing, WDT, leveler, tamper or Puqpress, puck screen. With real products in the size of your portafilter.

Milkcalculates

Milk Foam Simulator

Add air first, then roll, then stop: see what happens in the pitcher, how milk, air and temperature shape the foam, and when the milk stays sweet.

Try it
Milkshows

Latte Art Trainer

From the side and from above: pouring from high up mixes the milk under the crema, low and close draws on top of it. That's how a brown blob turns into a heart, a tulip or a rosetta.

Try it
Watercalculates

Water Chemistry Simulator

Hardness and buffer shape taste and scale. See where your water sits on the SCA chart, with sample values for Zurich and Bern.

Try it
Grindercalculates

Coffee Grinder Simulator

How do flat or conical burrs and grind size change your coffee? With a particle distribution curve, explained in everyday language.

Try it
Beanscalculates

Roast Level & Freshness

How light or dark shapes acidity, body and bitterness, and why freshness is a window, not a date. Older beans can taste very good too.

Try it
Filtercalculates

Filter Coffee Simulator

Play through recipe in grams, temperature and grind size for pour-over and the like, with TDS and extraction yield as model values.

Cold Brew vs. Cold Drip

Immersion or percolation? Play through method, ratio and time: soft and sweet or clear and lively.

Filter Basket Finder

Find the right precision basket for your portafilter, your dose and your taste, with a cross-section animation and one sentence on who each basket is a good fit for.

Still have questions about your result? Jackson, our AI advisor, puts it in context, around the clock. Or the Machine Finder guides you to your setup with a few questions.

You'll also find us in person: in Bern and Zurich, many of the machines are set up and running, and there's an espresso waiting at the bar.
