Burglars have stolen between £20,000 and £30,000 of wine from a house in Combe Down.
Police are investigating the crime which happened some time between Monday, November 19 and Friday, November 23.
The thieves took around 40 cases of white wine and port and officers believe they must have had a vehicle nearby to transport such a large quantity.
Police want to hear from anyone who saw anything suspicious or a vehicle parked in the Summer Lane area.
They also want to hear from anyone who may have been offered fine wine or port for sale.
Anyone with information is asked to contact Bath police on 101.
