Craft Bartending Technique

Like Duolingo, but for Craft Bartending Technique. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

For the part of you with thirty open tabs that never became anything.

22 levels across 4 sections, about 44 minutes end to end, roughly 9 days at five minutes a day. It moves through Mechanics and Thermal Control; Cocktail Architecture and Flavor Balance; Speed, Station Setup, and Service Flow; and Aromatics, Texture, and Finishing. It assumes you already know the basics.

What you'll learn

Key ideas in Craft Bartending Technique

  • A cocktail reaches thermal equilibrium and ~20-25% dilution within 10 to 12 seconds of shaking.
  • Shaking beyond twelve seconds adds excessive water without making the liquid any colder.
  • Rapid ice impact quickly plateaus the temperature near -5°C to -7°C.
  • Keeping the spoon back against the glass prevents turbulent splashing and air pocket formation.
  • A proper push-pull stir maintains glassy visual clarity in spirit-forward drinks like the Martini.
  • Lifting the spoon blade introduces pocket aeration that turns clear spirits cloudy.
  • Dry shaking without ice emulsifies and unfolds egg albumins at room temperature.
  • Adding ice only after initial emulsification locks the foam structure while chilling.
  • Straining separates the chilled liquid while preserving a dense, velvety head.
  • Pushing the strainer hood forward closes the gate, trapping foam and ice shards inside the tin.
  • Opening the gate wide allows airy egg-white or citrus foam to pass into the coupe unhindered.
  • Fine-mesh strainers catch microscopic ice shards that otherwise melt fast in a stem glass.
  • Floating ice micro-shards cause uncontrolled, rapid secondary dilution in drinks served up.
  • Sieve filtration preserves a velvety surface sheen instead of an uneven, icy crust.
  • Greater surface area relative to volume accelerates meltwater release
  • Larger ice cubes yield maximum chilling with minimal liquid dilution
