Giaconda's estate vineyard is managed sustainability and carefully according to environmental consciousness. Since 2018 they have been fully certified organic by the Bio Dynamic Research Institute (BDRI). The Australian Demeter Bio-Dynamic Method is a world leader in practices of ecological and sustainable farming.
At an altitude of 400+ metres (1,312 feet) the site and climate are influenced by the surrounding alpine valleys. The Chardonnay is planted on a relatively cool south-facing slope which is sheltered from the direct impact of the sun's rays. This results in a much slower ripening period, greater flavour complexity and natural acid levels. The Estate lies in a small valley which benefits from a light breeze much of the time; this is very effective in controlling disease.
The soil is 450 million year old granitic loam over decomposed gravel and clay. The clay is important in allowing sustained water-release to the vine roots; while the soil, being not too rich, is ideal for wine quality - lower yields are naturally regulated. The vines are drip irrigated in hotter years only when it is necessary to prevent vine stress. The average rainfall is 800 mm annually, a little of which can be received during summer. Nights are generally cool with days being fairly warm, providing ideal conditions for slow ripening. Vintage begins in late February or early March, depending on the season. All grapes are hand-picked in the cool of the early morning before being processing at the winery on site. Cropping levels are approximately 2.5 tonnes per acre.
To Giaconda wine making should be subtle and always seek balance - this should never seek to dominate the Terroir or characteristics of any given vintage. Giaconda wines are hand-crafted according to basically a natural wine making process. To us this means indigenous yeasts are employed for fermentation, natural bacteria for Malolactic fermentation, French oak barrel ageing, minimal sulphur additions, and no filtration before bottling.
The winery, barrel maturation cave and bottling facility are all set up for gravity flow. This means the wines are very rarely pumped or manipulated mechanically. Instead they are gently moved by gravity or gas pressure during the entire wine making process.
In the case of Chardonnay, fruit is hand picked, lightly crushed and then basket pressed - before being transferred to French oak barrels (approximately 30% new) for fermentation and ageing. For the red wines, a combination of whole bunch and de-stemmed crushed fruit is transferred to large concrete tanks for fermentation. These wines remain on skins for an extended period to develop softer, finer tannins and more complexity; before being basket pressed and transferred to French oak barrels (up to 40% new in some cases) for ageing.
Wines are aged in French oak for almost two years - deep underground in the granite purpose built maturation cave. This cave offers optimal conditions for fermentation and ageing with a stable temperature of 16 degrees centigrade and naturally high humidity all year round.
