The Chateau Lafite Rothschild wine, one of the most expensive reds in the world, could be worth up to £10 million ($16m) if it's found to be genuine.
Police suspect that the stash is fake and are already searching for the illegal workshop.
With only 50,000 bottles of genuine Chateau Lafite Rothschild imported into China each year, officials say that 70% of the bottles sold in the country are counterfeit.
The large house in Wenzhou reportedly had good security including five guard dogs.
However, the homeowner, known as Zou, told police that the property had been empty for nine years, and that he knew nothing about the potentially valuable find.
