There is no single formula for all wines, but there should always be balance between the flavors.
There is no single formula for all wines, but there should always be balance between the flavors. If a wine is too sour, too sugary, too astringent, too hot (alcoholic), too bitter, or too flabby (lack of acid) then it is not a well-balanced wine. If it is young, it is not likely to age well; if it is old, it may be falling apart or perhaps completely gone.
