Robert Parker is the foremost wine authority on the planet. His rating system (oddly enough) has been accepted worldwide, and if he says a wine is a '92', baby, it's gonna knock your socks off!

The URL above is for "the wines of the week" and is a good place to start for your Aunts. If you want some more latitude,

this is the vintage chart. Take a second and pick out the gold and Hot Pink vintages… You can bet that almost any bottle in these categories of these years is going to be wonderful, if not an outright world-beater!

Lucky Aunt you've got there!

Best wishes!
