Comparison
Bacchus vs Sémillon
How Bacchus and Sémillon differ, dimension by dimension.
The short answer
The main differences: Bacchus has more floral character; Bacchus has more herbal / green character; Bacchus has more aromatic intensity.
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.
Floral character
Clear differenceBlossom, rose, violet, elderflower, acacia and related aromatic notes.
Bacchus is more floral: medium-plus against low.
Herbal / green character
Clear differenceHerbs, grass, blackcurrant leaf, capsicum and other green notes, largely driven by methoxypyrazines and picking decisions.
Bacchus is more herbal and green: medium-plus against low.
Aromatic intensity
Clear differenceHow strongly the wine smells before it is tasted. Some grapes are intrinsically aromatic; others express mainly on the palate.
Bacchus is more aromatic: medium-plus against low-medium.
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.
Bacchus 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.
Sweetness
Clear differencePerceived sugar in the finished wine, driven mainly by residual sugar but modified by acidity, alcohol and fruit ripeness.
Sémillon is sweeter: medium against low-medium.
