ProcessRacking or soutirage is a traditional method in wine production of moving wine from one barrel to another using gravity rather than a pump. The process is repeated when the casks are moved to the second-year cellar.[5] Soutirage was developed in the Bordeaux region of France in the 19th century at a time when there was no electricity to power pumps. Many estates such in Bordeaux and some estates in Pomerol and St. Emilion still employ this labor-intensive method. During aging, the wine is decanted several times from barrel to barrel. This process softens tannins, clarifies the wine and enhances aromatic qualities. According to Oz Clarke, "traditionally the wine is 'racked' or drawn from barrel or tank to another empty one on a number of occasions (called soutirage). This helps clarify and freshen the wine by removing the fine lees or sediment which forms and provides a tiny amount of oxygen to help the aging process. The wine may also be 'fined' (collage) using egg white or other materials to settle out particles in suspension which are then removed through further racking."[6] Egg white is often applied to each barrel during the process.[7] EquipmentA racking hose is a flexible, plastic hose, used to siphon wine or beer from one vessel to another. It is used in both racking and bottling operations. A racking cane is a rigid tube, often bent or "L"-shaped, that is attached to the racking hose to make racking easier.[4] A protective cap is placed over the lower end of the cane that allows liquid to be drawn into the cane from above rather than below while keeping most large solids out. The cap allows the tip of the cane to be lowered close to the lees without unduly disturbing them. The lower tip of the racking cane should initially be held about midway between the surface and the lees and gradually lowered as the volume decreases due to the siphoning.[4] See also
