Decoding the Glass
Like Duolingo, but for Decoding the Glass. 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.
A short one: 13 levels across 2 sections, about 26 minutes end to end, roughly 5 days at five minutes a day. It moves through The Sensory Ritual and Structure and Selection. It starts from scratch.

Key ideas in Decoding the Glass
- Thick-skinned grapes produce darker colors
- Swirling increases surface area
- Red wines turn brown with age
- Swirling evaporates alcohol to carry aroma
- White wines get darker with age
- Glass shape traps scents
- Color depth and age
- The purpose of swirling
- Short, quick 'bunny sniffs' move air more effectively over the olfactory sensors
- One long inhale numbs the scent receptors quickly
- The motion evaporates alcohol which carries aroma molecules to the top of the glass
- Taking breaks between sniffs prevents 'nose fatigue'
- Sucking in air (slurping) while the wine is on the tongue releases volatile compounds
- White wines actually get darker and more golden with age
- Aeration in the mouth allows the aromas to travel to the back of the nose
- Mixing air with the wine makes the flavors taste more intense and complex
