After electric cars, space rockets, tunnel-boring technology and high-speed transportation systems, Elon Musk appears to be branching into booze.

Musk had Twitter tongues a-wagging, after posting a simple tweet that read "Teslaquila coming soon..." and linking to a CNBC article revealing that the entrepreneur had filed an application with the US Patent and Trademark Office to trademark the name "Teslaquila."

That tweet was followed by a photo titled "Visual approximation" featuring a red bottle label with a banner that reads "Teslaquila" under the company's signature Tesla logo.

The trademark is for "distilled agave liquor" and "distilled blue agave liquor," says CNBC. Followers of the prolific entrepreneur may remember a cheeky Tweet posted as an April Fool's Day joke earlier this year, in which he claimed Tesla was going under and that he had been caught passed out in a Tesla Model 3 car surrounded by "Teslaquila bottles."

While there's little else in the way of official information about the Tesla-themed tequila, CNBC points out that the company filed an "intent to use" trademark for the name, which means they have "good faith intention" of using it in the future.
