Wines as Gifts

[Rnf]

I have had the pleasure of receiving wines as gifts. But I usually get wines I do not know much about. Here are three:

1997 Quintessa Rutherford - Red Wine
1993 Barrel Reserve Randall Monroe Cabernet
1998 Pine Ridge Cabernet - Rutherford

What can I find out about them? I am always curious about the price. Finally, would you open and enjoy now or hold and enjoy later ---- if later how much later

thanks
