We can’t all be billionaires—but at least we can drink like one.

Wine expert and writer Mark Oldman has coined the term “billionaire drinker”in his third book, How to Drink Like a Billionaire. As he defines, it’s not someone who can afford the most expensive spirits—it’s someone who can find the most delicious bottles for the best price.

Oldman’s primary motto is “price is not necessarily proportionate to deliciousness.”

“After a certain price, you’re paying less for inherent quality—the grapes, the selection, the barrels—and you’re paying for other things: the scarcity, the story behind it, the critical scores,” he said. “Or, it could simply be priced higher so we value it more—the luxury good effect.”

To get the best taste for your money, his first tip is to “buy wine from a region not known for it because you’re probably going to pay a premium getting a Cabernet from Napa (Valley).”
