* first you are commenting on commercial wines so I will assume they are well made/ you are not reacting to defects which home wine can have
* front note should be sweet and last fifteen seconds
* the second note should be a weak wave of acid, (on a white this will last about a minute then leave the mouth saliva in a normal condition)
* with a red this will combine with a tannin note, astringent, rough on the roof of the mouth and tongue, this can last two to five minutes. (Tannin is combining with proteins that make saliva/ normal lubrication)
* the third wave can also have a bitter note
* on a young wine and white there should be fruity aromatics. (pinch your nose before you drink to block aromatics going to the nasal cavity). A good wine has aromatics that will have code words as HINTS of plum
* balance is a key. ,,, How fast does your mouth wash clean and return to start state ,,, are sweet notes longer than normal and overpowering acid. ,,, Are the acids overpowering so you want to spit it out (like tasting raw rhubarb in the garden)
* sugar (residual sugar in wine) fixes problems, humans like sweet, and sweet magnifies fruity sensations
* oak? ,,, hints of vanilla? more tannin note? smokey note?
If you experiment with expensive wine / $200 and $500 you will find the flavors are softer and don’t jump out as much as with $25 wine. There is balance between sweet and acid and the mouth returns to a no tannin condition faster.
