The truck was taken from Montclair, California, while carrying 40,000lb of beer.

Pabst has posted several appeals on Instagram, including an offer to waive questions if the truck and its cargo are returned within a specified period.

“Pabst is officially starting the clock now – you have exactly 18 days and 44 minutes to return our truck, no questions asked. Leading up to that time, we will be offering a reward to anyone who can help us solve this mystery,” the company said.

“P.s. this is real and we are deadly serious.”

The company said it was working with local authorities to recover the truck and added: “We hope that whoever managed to steal our truck also knows the importance of keeping beer cold.”
