Is the winemaking operation of storing a fermented wine in wooden barrels to create ideal conditions for the components of the wine to evolve and so that the wood imparts some oak flavour.
Is a complex of sensations resulting from the shrinking, drawing, or puckering of the tissues of the mouth. The most important astringent materials are tannins.
The most important, and variable, appellation in the southern Rhône in terms of quality, producing mainly rich, spicy, full-bodied red wines which can be some of the most alluring expressions of warm-climate viticulture, but can also be either impossibly tannic or disappointingly jammy.
Essential element for healthy vine growth. A deficiency of zinc affects the plant's ability to synthesize the hormones auxins, deficiency in which results in a failure of the shoots to grow normally.
Before concrete, stainless steel, and other inert materials replaced wood as the most common material for wine fermentation vessels and storage containers in the 1960s, each wine region had ist own legion of barrel types. Even today such terms as feuillette, tonneau, and fudre may be used to measure volumes of wine long after the actual containers themselves have been abandoned.
Or insert, planks of wood, usually oak, placed in a stainless steel tank and held in position by a metal framework, are a way of imparting oak flavour to wine more cheaply than by fermenting or ageing in barrels since the staves are easily replaced.
French for "white of blacks", describes a white wine made from dark-skinned grapes by pressing them very gently and running the pale juice off the skins as clear as possibl.
White winemaking technique wheereby the grapes are not subjacted to destemming and bunches of ripe grapes are pressed whole, with the stems used as conduits for what can often be particularly viscous juice.
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.
Is just west of, and very much smaller than, the much more famous Sancerre, near the city of Bourges, producing a not dissimilar range of red, white, and rosé wines which can often offer better value.
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%.
Are the dissolved inorganic constituents of vines, grapes and wine, often called nutrients, and primarily obtained from geological minerals in the groung.
Occasionally RS, the total quantity of sugars remaining unfermented in the finished wine. This may include both fermentable sugars, mainly glucose and fructose, which have for some reason remained unconverted to alcohol during fermentation, and small amounts of those few sugars which are not readily fermented by typical wine yeast.
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.
French word for the important operation in the production of fine wines of deciding which lots will be assembled to make the final blend. It plays a crucial role in sparkling winemaking when some cuvées may be assembled from several hunderd different components.
Qualitätswein is what POD wines are called in German. This is Germany's largest and lowest wine category and in practice includes all those wines once known as QbA. The grapes must originate in one of Germany's 13 official wine regions and reach minimum must weights.
