Decoding the Bottle
Like Duolingo, but for Decoding the Bottle. 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: 10 levels across 2 sections, about 20 minutes end to end, roughly 4 days at five minutes a day. It moves through The Architecture of Taste and Navigating the World. It assumes you already know the basics.

Key ideas in Decoding the Bottle
- Tannins are polyphenols that bind to saliva, creating a physical drying sensation.
- Acidity triggers salivation, which cleanses the palate and makes a wine feel refreshing.
- High-tannin grapes like Cabernet Sauvignon affect the gums and cheeks, not the tongue's taste buds.
- A 'spine' of acidity prevents high-alcohol or oaky wines from feeling cloying or flat.
- Distinguishing tannin as a physical sensation rather than a taste
- Recognizing the role of acidity in balancing wine structure
- Alcohol increases the viscosity of wine
- Distinguishing tannin as a physical sensation
- Mapping alcohol levels to perceived body
- The finish measures flavor persistence
- Role of acidity in balancing wine structure
- High-quality wines have a long finish
- Fruitiness is an aroma (nose), while sweetness is the physical presence of residual sugar (tongue).
- Mapping alcohol levels to the perceived body of the wine
- A wine can smell like sweet tropical fruit but have zero sugar, a profile common in 'dry' aromatic whites.
- Using the finish to judge wine quality
