The Logic of the Label
Like Duolingo, but for The Logic of the Label. 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: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through The Architecture of the Sip and Decoding the Professional Bottle. It assumes you already know the basics.

Key ideas in The Logic of the Label
- Acidity provides the structural lift that balances fruit sweetness
- Tannins are polyphenols that create a drying, astringent 'grip' in the mouth
- Low acid wines are described as 'flabby' or 'flat' on the palate
- Tannic sensation is felt physically on the gums and inner cheeks
- High acidity creates a mouth-watering sensation that cleanses the tongue
- Tannins come from grape skins and seeds, providing texture rather than taste
- Higher alcohol increases a wine's viscosity, making it feel 'heavier'
- Low-alcohol wines (under 12.5%) feel light and watery like skim milk
- Recognizing the structural role of acidity
- High-alcohol wines (over 14%) feel rich and coating like whole milk
- Balance occurs when acid, tannin, and alcohol are in harmony
- Distinguishing the tactile sensation of tannins
- A balanced wine doesn't have a 'burning' finish from excessive alcohol
- In balanced wines, the fruit concentration matches the structural intensity
- Ranking wines by their 'weight' or body based on alcohol content
- Identifying a balanced wine
