The man showed up at the facility Friday afternoon, signed a slip for the drinks, used a forklift to load them on to a truck and left, company officials said.
"We realized this happened when our real driver showed up a couple of hours later," BluePrint co-founder Zoe Sakoutis said.
The shipment was meant to be delivered to a facility in Allentown, Pa., which would have pressurized the drinks before they hit stores, the New York Post reported Saturday.
Without the pressurizing, the raw drinks only have a five-day shelf life, as opposed to the standard 30-day shelf life.
BluePrint began as a small boutique store in Chelsea before growing to a $20 million operation, the Post reported. The cleansing drinks sell for an average of $10 and include flavors like lemon cayenne agave and cashew vanilla cinnamon agave.
