Theory 120/Wine ageing/Ratio lens
Longevity Is Tannin Against Acid
The claim
Ageing potential is set by the ratio of tannin to acid, so a wine needs both in proportion rather than either in quantity.
01Mechanism
Tannin provides structure and acid provides protection; the ratio determines how the wine evolves.
02Prediction
Longevity should track the ratio.
03Refutation
Longevity tracking tannin alone would remove acid.
