The acquisition was completed with further financing from ISIS, which invested £8.2 million in a management buy-out of Enotria in December 2005.

Great Western Wine’s managing director Philip Addis, who founded the company, will join Enotria’s board under the terms of the transaction.

The deal follows Enotria’s acquisitions of Wheeler Cellars and Select Vineyards in 2008, which were also backed by ISIS.

London-headquartered Enotria has recently appointed ex-Majestic chief executive Tim How to its board as deputy chairman.
