Comparison
Assyrtiko vs Sémillon
How Assyrtiko and Sémillon differ, dimension by dimension.
The short answer
The main differences: Sémillon has more sweetness; Assyrtiko has more perceived freshness; Assyrtiko has more acidity.
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.
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.
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.
Assyrtiko is fresher: high against medium.
Acidity
Clear differenceTotal perceived acidity. Rises in cooler climates and with earlier picking; falls with heat and ripeness.
Assyrtiko is fresher and more acidic: high against medium-plus.
Alcohol
Clear differencePerceived alcoholic strength, which tracks actual ABV but is modified by sweetness, acidity and body.
Assyrtiko is stronger and warmer: medium-plus against medium.
Body
Clear differenceThe overall weight and viscosity of the wine in the mouth — a composite of alcohol, sugar, extract and glycerol.
Assyrtiko is fuller and richer: medium-plus against medium.
Aromatic intensity
Clear differenceHow strongly the wine smells before it is tasted. Some grapes are intrinsically aromatic; others express mainly on the palate.
Assyrtiko is more aromatic: medium against low-medium.
