Scale 1
Macro
How many wines of each quality exist? Red and white diverge in distribution shape — not just flavour.
Scale 2
Meso
Select any chemical feature. See how Low / Mid / High quality wines pull apart — or don't.
Scale 3
Micro
Each quality score (3–9) is its own distribution. A score of 6 hides more chaos than you'd expect.
Red Wine
Solid lines throughout. Darker = lower quality score, brighter = higher.
White Wine
Dashed lines (micro view). Warm amber palette from low to high quality.
Low
Mid
High
Quality tiers used in the Meso view: ≤5 · 6–7 · ≥8.
