Why does Austrian Sekt taste like that?

Characteristically very low tannin and medium-plus acidity. Commonly associated with green apple, white pepper, lentil, celery.

Not claiming: That every wine from this variety shows these characteristics. This is the range across the category, and site and winemaking move wines within and beyond it.

Characteristically very low tannin, high acidity and light-medium body. Commonly associated with lime, green apple, white peach, apricot.

A wide day–night temperature range is associated with better acid retention, because cool nights slow the respiration that consumes malic acid while warm days continue to ripen the fruit.

Not claiming: That altitude or continentality guarantees high acidity. Both widen diurnal range on average and neither determines the outcome.

The traditional method leaves the wine on its lees in the bottle after the second fermentation, which is where autolytic bread and brioche character develops. Minimum ageing periods are set by appellation rules.

Not claiming: That minimum periods are the same across appellations, or that tank-method wine is inferior — it is made to preserve primary fruit instead.

Autolysis of spent yeast releases mannoproteins and other compounds that contribute texture and weight, and savoury bready characters.

Varies: Effect scales with time and is increased by stirring the lees.

Not claiming: That a bready or brioche character proves long lees ageing. Other routes to similar descriptors exist.

The Klassik tier is for drinking young. Reserve and Grosse Reserve carry substantially longer mandatory lees ageing and will keep five to ten years after release.

Not claiming: That a wine of this style will develop these characters. Ageing potential varies by producer, vintage and storage, and most wine is better young.
