Back in September, Billy Chasen had a mission: concoct the single most expensive Starbucks drink he could. The winner?

I told the barista that I was there as part of a contest to make the most expensive drink. She played along, trying to squeeze as much as we could into a venti cup. She thoroughly enjoyed the problem at hand (although other customers on line were getting peeved).

And the ultimate yuppified result: A 13 shot venti soy hazelnut vanilla cinnamon white mocha with extra white mocha and caramel. It cost a total of $13.76 (with tax).

Chasen's post went up on September 28. Jim Romenesko's Starbucks Gossip linked to his post this morning. And after three months and industry blog exposure, no one's come up with a drink more expensive than Chasen's.

We don't drink coffee. And we certainly wouldn't drink that. But we'd love to know if someone out there has cracked the $14 drink barrier. You?
