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
Acids in wine has completed one successful malolactic fermentation will almost always induce MLF in every wine stored in it from then on. While very common in citrus fruits, such as limes, citric acid is found only in very minute quantities in wine grapes. It often has a concentration about 1/20 that of tartaric acid. The citric acid most commonly found in wine is commercially produced acid supplements derived from fermenting sucrose solutions. These inexpensive supplements can be used by winemakers in acidification to boost the wine's total acidity. It is used less frequently than tartaric and malic due to the aggressive citric
