Racking: The practice of moving wine from one container to another for aeration or clarification, leaving sediment behind.
Cold Stabilization: A clarification technique that can prevent the formation of crystals in wine bottles. Prior to bottling, the wine's temperature is lowered to approximately 30° F for two weeks, causing the tartrates and other solids to precipitate out of solution. The wine is then easily racked off (separated from) the solids.
Sur Lie: Wines aged sur lie (French for "on the lees") are kept in contact with the dead yeast cells and are not racked or otherwise filtered. This is mainly done for whites, to enrich them. (It is a normal part of fermenting red wine, and so is not noted.) The concept originated in Burgundy, with Chardonnay, but is now popular around the world with numerous white grape varieties. Sur lie aging can be overdone, leading to an off-putting leesy flavor.
Riddling: In making sparkling wine, the process of moving the sediment remaining in the bottle from the second fermentation to rest on the cap for easy removal. The process of riddling is unique to méthode traditionelle and was developed by Madame Clicquot (Veuve Clicquot) in the early 1800s to remove the cloudy lees from the bottles. The bottles are loaded in a horizontal position onto wooden racks called pupitres. At this point, the sediment rests on the side of the bottle. As the bottles are riddled, or given a sharp quarter-turn daily and gradually tilted upside-down, the sediment works its way to the bottle neck. Today, most producers use efficient mechanical riddlers.
Kosher Wine: Wine made according to Jewish dietary laws (the kashrut) and certified by rabbinical authorities. Only observant orthodox Jews can handle kosher wine during the winemaking process, including tasks such as racking and drawing samples from barrels. Common fining agents forbidden in the production of kosher wine include casein and isinglass, though the use of egg whites is permitted.
Winemaking: Largely synonymous with "Vinification," winemaking is the process by which harvested grapes are crushed, fermented (and otherwise manipulated through yeast inoculations, temperature control, punch-downs, pump-overs, racking, oak-chip additions, filtering, etc.), aged in barrel, steel tank or other vessel, and finally bottled.
