Comparison
Riesling vs Sémillon
How Riesling and Sémillon differ, dimension by dimension.
The short answer
The main differences: Riesling has more aromatic intensity; Sémillon has more oak influence; Riesling has more floral character.
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.
Aromatic intensity
Clear differenceHow strongly the wine smells before it is tasted. Some grapes are intrinsically aromatic; others express mainly on the palate.
Riesling is more aromatic: medium-plus against low-medium.
Oak influence
Clear differencePerceptible impact of barrel or alternative oak contact — vanilla, toast, coconut, smoke, cedar and added texture.
Sémillon is more oaky: medium against low.
Floral character
Clear differenceBlossom, rose, violet, elderflower, acacia and related aromatic notes.
Riesling is more floral: medium 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.
Riesling is fresher: high against 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.
Sémillon is rounder and creamier in texture: medium-plus against low-medium.
Acidity
Clear differenceTotal perceived acidity. Rises in cooler climates and with earlier picking; falls with heat and ripeness.
Riesling is fresher and more acidic: high against medium-plus.
