tasting tips wanted

[Major Rex]

Hello all - firstly what a wonderful site this is!!
I am interested in the procedure for actual tasting the wine.
Specifically where and what to taste for in different parts of the palate. All I remember from a wine course years ago was that tannin is tasted on the upper gum between to top lip and teeth. (make sense?). What about acid, fruit, oak etc.
Any help greatly appreciated to the forum or home email.
Thanks
Rex
