Confusion Matrix
Inference : For the shortest Branch of the tree
If Chloride </=0.06,
Total SO2</=54, </=88.5
Volatile acidity<=0.465,
Sulphates</=0.705, </=1.35
Then Yes the Wine is White
Low Acidity along with Chloride, SO2 & Sulphate gives
White Wine
White Wines are loved for their Zesty acidity, floral
aromas & pure fruit note (No Oxidation)
Min –Max
Chloride - 0.009-0.611
Total SO2 - 6-440
Volatile Acidity - 0.08-1.58
Sulphates - 0.22-2
White Wine & Red Wine
White Wines are loved for their Zesty acidity,
floral aromas & pure fruit note (No Oxidation)
Red wine is made when the crushed grapes are
fermented for one or two weeks in Oak barrels;
whereas white wine is made when the skin and
seeds of white grapes are removed and mixed
with yeast and aged in stainless steel vats for
fermentation.
