Strong growth in white wine production underpinned a record 2005 vintage, the Winemakers Federation of Australia has reported.

The statistics, based on a members' audit, confirmed earlier projections of a bumper year.

Federation chief executive Stephen Strachan said the 1.824m tonne crop was 6% up on 2004.

The white crush was up 13.5% and red just 0.5% even though Australia's continuing export boom is fuelled by demand for reds.

Chardonnay has replaced Cabernet Sauvignon as the second most popular grape behind Shiraz.

"Most areas enjoyed favourable seasonal conditions during both ripening and vintage, delivering quality across all our major regions," Strachan said.

"Although record vintages for two years running could compound some of the supply challenges facing our industry at present, reassuringly the volume of Australian wine sales has continued to grow in both the domestic and export markets."
