Arneis wine grapes in Western Australia

Page last updated: Tuesday, 7 November 2017 - 1:29pm

Arneis is an emerging variety in the Australian wine industry, with commercial plantings established in eastern states. Wine styles vary from light-bodied, dry and faintly grassy to a fuller style with distinctive peach with light oak. 

It has performed well in Manjimup with low disease susceptibility, moderate yields, producing fine and delicate wines.

Production of Arneis at Manjimup

In trials conducted by the Department of Agriculture and Food at Manjimup in the South West, Arneis (Clone CVT CN15) rootlings established well in the field and produced the first crop for wine production in 3.5 years.

This variety was spur-pruned, leaving canopies that required minimal shoot thinning early in the season.

Literature suggests that Arneis has low basal bud fertility, however this was not the case here. Arneis produced at least one bunch per shoot, with many secondary bunches removed at veraison to allow adequate ripening.

Approaching harvest, Arneis fruit is sensitive to sunburn, requiring canopy management to ensure adequate leaf coverage.
