An accumulation of clay and silt particles that have been deposited by the wind. Loess is typically pale-coloured, unstratified, and loosely cemented by calcium carbonate. Favoured for viticulture because it is porous, permeable, readily warmed and easily penetrated by roots.
The lightest in terms of must weight and alcohol among the trio of dry white wine categories in Austria's Wachau region-specifically for unchaptalaized grapes of 73 to 83° Oechsle which result in wines no more than 11% alcohol.

Stirring up the lees in the barrel also effects oak flavour.
Is French for "old vines". The term is used widely on wine labels-as is vinhas velhas (Portugal), alte Reben (Germany)-in the hope that potential buyers are aware that wine quality is often associated with senior vine age.
