DAOSA crafts premium sparkling wines using the traditional Méthode Classique. By managing their own vineyards in the cool-climate heart of the Piccadilly Valley, they ensure exceptional fruit quality. Every step of the process, from hand harvesting to extended lees ageing, is carefully chosen to produce wines of finesse, complexity, and balance that truly reflect their unique site.

The Bizot vineyard is located in Summertown, in the heart of Piccadilly Valley sub-region in the Adelaide Hills, and is one of the highest vineyards in the valley at 550m altitude. It was planted by Petaluma in 1995/1996 for DAOSA with Chardonnay. It was planted with several clones, including French “Burgundy” clones 76, 95, 96 and 277. It is also one of the first Australian vineyards to have been planted using rootstocks in part of the vineyard. The soil is red clay and sandy loams over a 70 million year old shale rock formation. The Chardonnay is planted on a north-north east facing slope, at a relatively high density of 3,200 vines per hectare.

The juice was very clear with great acid balance and good primary fruit characters. The juice was cold settled in tank before being run into old 600L barrels for primary fermentation. Once primary fermentation was completed, the barrels were topped and the wine stayed in barrel, with some lees stirring, for a further 6 months where it went through malolactic fermentation.

The wine was then tiraged in October 2021, by the addition of yeast and sugar to the wine just before bottling,to induce the secondary fermentation in bottle. The resultant sparkling wine was aged for over three and a half years in bottle before being disgorged with the addition of a low dosage of 4g/L in June 2025. The DAOSA Blanc de Blancs 2021 has spent more than 4 years on lees in total, in barrel and in bottle.

Tasting Note

"A pitch-perfect Blanc de Blancs. This stellar release offers up richness, savoury detail of brioche and nougat and bristles with mineral charges of brine and chalk. It goes taut with citrus and crunchy green apple characters. Layers on layers of flavour and yet a levity and vitality in tow. A marriage of all the right elements here." 95 points - Halliday Wine Companion, Mike Bennie (2025).
