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. The name comes from a feathery grass species indigenous to the local vineyard terraces.
Methods of vine training, which vary considerably around the world. The word describes the actions of pruning in winter and summer, and shoot and cane placement, so that the vine's trunk, arms, and cordons and buds are appropriately located on the trellis system.
Widely used in filtration, is a naturally occuring, highly porous, chalky textured sedimentary rock made mainly of silica and consisting of fossilized remains of diatoms, a type of hard-shelled algae.
Is a French synonm for Sauvignon Blanc, notably in Pouilly-sur-Loire, centre of the Pouilly-Fumé, or Blanc Fumé de Pouilly, appellation, many of whose aromatic dry whites do indeed have a smoky, if not exactly smoked, perfume.
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.
Downy mildew attacks all green parts of the vine and young leaves are particularly susceptible. When severly affected, leaves will drop off. The loss of leaves reduces photosynthesis and thus causes delays in fruit ripening and, typically, levels of fruit sugars, vine reserves of carbohydrates, and anthocyanins are depressed.
Term often used in France, particularly in Bordeaux, for the cellermaster, as opposed to the régisseur, who might manage the whole estate, or certainly the vineyards.
A fortified wine made by adding brandy to arrest fermenting grape must which results in a wine, red and sometimes white, that is both sweet and high in alcohol.
An instrument for measuring a refractive index, which is related to the amount by which the angle of a light wave is changed when passing through the boundary between two media. The amount of refraction is a convenient way to measure solute concentration of a solution and is widely used in viticultural and winemaking to follow the ripeness of grapes and changes during vinification.
Is by German law a rosé wine at least 95% of which is made by direct pressing of a single red wine grape variety named on the label (Spätburgunder and Portugieser are especially common).
French term for racking, or moving clear wine off ist sediment and into a clean container. It can also be used for the wine serving process of decanting.
Named after the principal town of Nuits-St-Georges, this is the northern half of the escarpment of the Côte d'Or, producing the greatest red wines of Burgundy, from the Pinot Noir grape, and very occasional white wines.
French term meaning "bled" for a winemaking technique which results in a rosé wine made by running off, or "bleeding", a certain amount of free-run juice from just-crushed dark-skinned grapes after a short, prefermentation maceration.
Sleep, the normal state of vines in winter. This period normally starts with autumn leaf fall, although buds are in a state of so-called organic dormancy from veraison onwards.
French word for various systems of pumping over. In winemaking terms it is the pumping of the liquid in the fermentation tank over the cap of skins and solids during the red wine fermentation.
The most valuable category of white wines made from the ripest grapes on the best sites of the Wachau in Austria. The category is named after the green lizard that basks in the sun on the Wachau's steep stone terraces above the river Danube. Alcohol levels in the unchaptalized Grüner Veltliners and Rieslings that qualify must be more than 12.5%.
The practice of adding spirits, usually grape spirit, to wine to ensure microbiological stability, thereby adding alcoholic strength and precluding any further fermentation.
Microscopic, single-celled fungi, having round to oval cells which reproduce by forming buds, are vital to the alcoholic fermentation process, which, starved of oxygen, transforms grape juice to wine.
