Where they genuinely differ
Only differences large enough to notice in the glass are listed here. A gap of half a point on a five-point scale is noise, and WineHQ does not dress it up as a finding.
Acidity
Clear differenceTotal perceived acidity. Rises in cooler climates and with earlier picking; falls with heat and ripeness.
Sauvignon Blanc is fresher and more acidic: high against low-medium.
Floral character
Clear differenceBlossom, rose, violet, elderflower, acacia and related aromatic notes.
Viognier is more floral: high against low-medium.
Herbal / green character
Clear differenceHerbs, grass, blackcurrant leaf, capsicum and other green notes, largely driven by methoxypyrazines and picking decisions.
Sauvignon Blanc is more herbal and green: medium-plus against low.
Perceived freshness
Clear differenceThe overall impression of liveliness — a composite of acidity, alcohol balance, fruit character and the absence of tiredness. Distinct from raw acidity: a wine can be high in acid yet taste heavy.
Sauvignon Blanc is fresher: high against low-medium.
Texture
Clear differenceMouthfeel independent of weight — from lean and cutting through to creamy, waxy or velvety. Driven by lees contact, malolactic conversion, skin contact and ageing.
Viognier is rounder and creamier in texture: high against low-medium.
Body
Clear differenceThe overall weight and viscosity of the wine in the mouth — a composite of alcohol, sugar, extract and glycerol.
Viognier is fuller and richer: high against medium.
