Sweetness of wine or the slightly sweeter classification of "Brut" or even "Extra Dry/Extra Sec/Extra Seco" (because 9 + 3 = 12 grams per litre). The rules applicable to labellings before 14 July 2009 were: In Austria, the Klosterneuburger Mostwaage (KMW) scale is used. The scale is divided into Klosterneuburger Zuckergrade (°KMW), and very similar to the Oechsle scale (1 °KMW =~ 5 °Oe). However, the KMW measures the exact sugar content of the must. In Canada, the wine industry measures wine sweetness as grams of sucrose in 100 grams of grape juice or grape must at 20 °C in degrees Brix. In
Phenolic content in wine increase during ripening so does the concentration of anthocyanins. In most grapes anthocyanins are found only in the outer cell layers of the skin, leaving the grape juice inside virtually colorless. Therefore, to get color pigmentation in the wine, the fermenting must needs to be in contact with the grape skins in order for the anthocyanins to be extracted. Hence, white wine can be made from red wine grapes in the same way that many white sparkling wines are made from the red wine grapes of Pinot noir and Pinot Meunier. The exception to this is the small class of
