Wine Structure and Longevity
Move past superficial tasting notes to diagnose the biochemical architecture of wine. Analyze acid-tannin balance, evaluate redox dynamics, and accurately predict cellar evolution.
Like Duolingo, but for Wine Structure and Longevity. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
A short one: 8 levels across 2 sections, about 16 minutes end to end, roughly 3 days at five minutes a day. It moves through Structural Diagnostics and Prognosis and Evolution.

Key ideas in Wine Structure and Longevity
- Malic acid imparts a sharp, mouthwatering green-apple crunch that cellar masters intentionally preserve by chilling or sulfuring to block malolactic fermentation
- Tartaric acid additions register as an abrupt, hard, and isolated angularity along the lateral tongue borders when rebalancing warm-climate musts
- Lactic conversion softens the dicarboxylic malic acid into a smoother, rounder mono-acid, fundamentally altering perceived mouthfeel
- Ripe skin tannins yield fine-grained, velvety chains via polymerisation that coat the palate evenly without lingering bitterness
- Unripe or damaged seeds release monomeric catechins and low-molecular phenolics that register as harsh, lingering bitterness at the back of the tongue
- Over-maceration and aggressive mechanical extraction strip unripe seed tannins and herbaceous stalk phenolics, causing abrasive, unyielding friction
- Dry extract—consisting of dissolved solids, glycerol, polysaccharides, and minerals—supplies the physical weight and mid-palate cushion required to counterbalance high acidity and aggressive phenolics
- Wines deficient in dry extract age into hollow, austere, and unpleasantly stripped skeletons because tannins outlive the insufficient fruit extract
- True aging potential demands structural equilibrium: intense acid and phenolics supported by proportionate dry extract concentration
- Solar dehydration elevates sugar content via water evaporation, yielding elevated alcohol without mature skin and seed phenolics
- Diagnostic sensory signatures of distinct acid types to determine specific cellar vinification decisions
- Desiccated fruit manifests as a hot, burning finish accompanied by raisins, prunes, and a surprisingly hollow, astringent mid-palate gap
- Physiological ripeness pairs high potential alcohol with rich fruit extract, fully polymerised sweet tannins, and fresh aromatic complexity without alcoholic burn
- Light hydrogen sulfide and noble flint reduction readily blow off and yield to fruit with splash decanting
- Heavier mercaptans and complex sulfides are chemically resistant to simple aeration and can oxidize into foul disulfides rather than clean up
- Copper contact or targeted cellar remediation resolves mercaptans, whereas air alone often compounds the sensory fault
