Craft Cocktail Mechanics, a free food & drink course on Tomo

Craft Cocktail Mechanics

Step beyond memorized recipe cards and understand how temperature, texture, and structural ratios govern great drinks. Learn to diagnose cocktails by sight and adjust dilution, aeration, and balance on the fly.

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

A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through The Physics of the Pour and Balance and Presentation. It assumes you already know the basics.

What you'll learn

Key ideas in Craft Cocktail Mechanics

  • A proper wash line should sit roughly a quarter-inch below the coupe's rim.
  • Under-shaking fails to add the necessary melt water, leaving total drink volume short.
  • The wash line instantly exposes whether total volume matches proper dilution.
  • Higher ice surface area accelerates melting and chill exchange in the drink.
  • A large single rock keeps spirit-forward drinks cold without flooding them.
  • Crushed or pebble ice melts rapidly to soften overproof spirits in Tiki drinks.
  • Standard shaking or stirring adds 20% to 25% water volume through ice melt.
  • Proper dilution lowers ethanol perception to reveal delicate aromatic compounds.
  • Cocktails served without sufficient melt taste harsh, unbalanced, and muted.
  • Room-temperature glassware causes thermal shock that pops and thins out egg-white foam.
  • A warm glass raises drink temperature instantly, accelerating ice melt on served rocks.
  • Excess melt water bleaches out the rich pigment and color saturation of syrups and spirits.
  • Over-dilution ruins body and viscosity, leaving the liquid's surface thin and flat.
  • Too much water weakens spirit emulsion, causing juices and aromatics to separate quickly.
  • Gliding the spoon along the wall keeps liquid in smooth laminar flow without trapping air
  • Bouncing or splashing the spoon whips tiny micro-bubbles into the spirits that haze the drink
