Yes....it depends. I only have a couple dozen bottles or so that I consider truly special, only in that I'll likely never be able to replace them. I've opened most of my previous "preciouses" with groups of 4-6 and one with two dear friends during a wonderful dinner.
I'm saving the rest for special moments. I don't know what they are yet, but I'll know them when I see them.
I voted "c" just because it's the closest to my track record so far.
