wasn't always used for rosé production. For some red winemakers, the juice bleed off is simply poured down the drain or used as "topping wine" to fill the ullage (the headspace of barrels and tanks) during storage. Its use in rosé production is sometimes considered an afterthought, as a way to increase cash-flow by producing a second wine to a primary red wine that can be released much sooner and available to market. While many wineries have been able to produce critically acclaimed rosé using the saignée method, its use has provoked criticism from wine personalities such as François Millo, president of the Provence Wine Council (CIVP) who claim that saignée method rosés are “not true rosés" because the bleeding process (which is not pressed with the must) is more of an afterthought. Vin gris Unlike the maceration method which gives some, albeit very brief, time for the juice to be in contact with the skins vin gris are wines made from the immediate pressing of red skin grapes without any maceration time. Despite the name vin gris, the resulting juice is actually not grey but rather a very pale pink that is usually much lighter than traditionally made rosés using the limited maceration and saignée methods. Under French wine laws, wines labelled gris de gris must only be made from lightly tinted grape varieties such as Cinsault, Gamay and Grenache gris. The style is a specialty of the Lorraine Appellation d'Origine Contrôlée (AOC) Côtes de Toul made from Gamay and in Morocco where the orange-pink wine is made from a blend of Cinsault, Grenache and Cabernet Sauvignon. Decolorization Another method of producing rosé is to severely decolorize a red wine using absorbent charcoal such as activated carbon. This purer form of charcoal obtained by the dry distillation of carbon compounds (such as wood or peat) has a high ratio of surface area to weight that adsorbs color compounds as well as other phenolics and colloids in a wine. While it can be used to decolorize a wine, often much more than just color is stripped from the wine which makes this method very rarely used in the production of quality rosés. Color With the exception of very few varieties, known as teinturiers, most wine grapes produce clear or colorless juice. This includes such well known red wine grape varieties such as Cabernet Sauvignon and Pinot noir. The color in
