A privately owned winery in Australia's Hunter Valley, Peppertree Wines, is on the market in whole or part with an estimated value of A$30m (US$14.7m).

Managing director Chris Cameron said the board would prefer to sell Peppertree, which also has interests in the Coonawarra district of South Australia, intact but had several parties interested in parts of it.

Peppertree is owned by James Fairfax, a member of a prominent Australian press and media family and sells premium wines domestically and overseas. Fairfax's decision to put Peppertree on the market followed rejection of a float option and a decision to halve production to 65,000 cases a year to rein in growth.

 According to press reports, Cameron said any buyer must be prepared to pay a premium as it was a business on the rise, not the slide.
