Sweetness scale

[Thomas]

Hello,

Tart and bitter are not the same sensation. Tart attacks the sides of the tongue, bitter is something that either coats the tongue or hits it at the back.

I don't know of any chart that exists. The closest, regarding wine, to a listing that I know of for the consumer is with wines from Ontario, Canada. There they have a numbering system that ostensibly identifies the level of sugar/sweetness in wine.

Why do you need the chart? Diabetic?
