As time has passed, the string rim has gotten much smaller and become an anachronism. If a wine is higher in components that mask sugar, such as acidity, tannin or alcohol, the normal threshold may be higher. Sulfites - Amino acids that result from the breakdown of proteins during fermentation. They may be added to through the addition of sulphur during the winemaking process. Tank - A large closed container used for the storing, fermenting or blending wine.
Tanks are often stainless steel, wood or fiberglass lined concrete.
Tannin - The astringent or bitter qualities in a wine come from tannins, which are found in grape skins, stems and seeds. Tannins are extracted from grapes by skin contact and heavy pressing. Another source of a different type of tannin called flavonoids, is aging in oak barrels. Subtle amounts of oak tannins can give wine an aromatic complexity that can be desireable. Thin - A descriptive term used to describe a wine that lacks much flavor, body or depth.
