Is this the most expensive Starbucks drink ever?

Sixty shots of espresso. A 128-ounce glass.

A Starbucks customer going only by Andrew claims he's ordered the coffee chain's biggest, most expensive drink to date.

The Sexagintuple Vanilla Bean Mocha Frappuccino cost $54.75, according to a receipt of the purchase he posted on Twitter.

But because Andrew is a Gold member of the Starbucks loyalty program, he got the concoction for free.

Starbucks confirmed the coffee colossus is the real deal.

But a spokesperson told The Huffington Post t hat while it does allow customers to customize free beverages earned through its reward program, this one "was excessive and something that we do not encourage."

"I gotta say, it was delicious," Andrew told The Consumerist.

And yes, he finished it.
