I have decided to give Scotch whiskey a try, so I went out and found a bottle of 12 y/o Cardhu. Thoughts on my choice?

I can't say there was any logic in this choice, as I don't really know much about Scotch other than to avoid anything less than 10 y/o, and to be honest, I don't even remember where I heard that bit of advice, but it was top shelf and in company with Glenfiddich, Glenlivet, and Glenmourangie.

Plus it comes in a really nice box!

Any suggestions on how I should enjoy it? Water? Ice? With food?
