Even if I was wealthy I probably wouldn't spend more than $1,000 on a bottle of booze. In most cases I wouldn't spend over $100.
I've been fortunate enough to taste some very high end wines and spirits, including a pour off a 1955 Barolo double magnum that went for $25,000 per bottle.
The thing with that stuff is, while some of it is very very good, it doesn't give you more pleasure in relation to its outlandish price.
$30K on a bottle of booze is for billionaires who can't spend their money fast enough. There is a limit to just how good something can be, and beyond that you're just paying for the fancy bottle, the handwritten label, the limited release, etc. There's a lot of bullshit marketing involved.
As far as single malt scotch goes, the best bottles tend to top out at around $300, but you can get any number of fantastic bottles for under 100. Over $300 and you're probably getting into the limited release stuff that's up for auction.
Nice call on the Blanton's btw ^^^ very good bourbon for that price range. A personal favorite.
