Why did it stand out so much? It's a nice medium-bodied red with lots of solid berry flavor and just a slight amount of spice. The finish is just right and lingers just long enough to remind you that you need another sip.
I emailed the winery and they forwarded the list of stores below. It retails in the "real world" under the name: 2004 Pedroncelli Cabernet Sauvignon Three Vineyards*. You can buy directly from the winery or find it at a good number of places with the Google Product Search.
Leave a comment if you have a chance to try it!

*Under the Stanford label it was called 2004 Dry Creek Valley Cabernet Sauvignon
