Despite being grown in Australian vineyards since the arrival of the First Fleet, chardonnay really only became popular in the 1970s and subsequently sales boomed through the 1980s. Today chardonnay is the second most widely planted variety in Australia (behind shiraz), with almost 32 000 hectares currently under vine.
Chardonnay is not only loved by wine drinkers, but it is also a favourite of winemakers and grape growers alike, and there are two major reason for this. The first reason is its ease of cultivation. Chardonnay is able to adapt to many conditions and hence is found in vineyards with very diverse climates – from the cold of Tasmania to the warmth of the Riverland. Many grape varieties are not capable of this, with varieties like pinot noir performing best in a cooler climate.
The different climates where chardonnay is grown are also reflected in the finished wine. Chardonnay from cooler climates taste more of gooseberry, grapefruit and lime, while warmer climates produce chardonnay with flavours of tropical fruit and rockmelon.
The second reason that winemakers love producing chardonnay is due to its malleability. There are a range of different winemaking practices that can be utilised in its production. This gives winemakers the opportunity to endlessly experiment with these different techniques. Some of the major winemaking techniques used in the production of chardonnay are:
Wild Yeast. Most wine is produced using cultured yeasts that have predictable behaviour, produce known characters and aromas in finished wine, and will tolerate a high alcoholic-strength environment. But wine can also be produced using the natural yeast strains that occur in the vineyard and winery. These wild or indigenous yeasts often produce some unusual flavours (often termed funky) that can add extra complexity to the finished wine.
Time on Lees. Called sur lie in French, this involves leaving the dead yeast cells, skin, pulp and grape seeds (collectively known as lees) that collects at the bottom of a vessel after fermentation in contact with the wine for two to twelve months (in some styles, even longer). The presence of the lees improves mouthfeel, by creating a creamy texture in the wine, as well as adding cream and yeast flavours. Often times lees-stirring (or bâtonnage), where the lees are regularly mixed in the barrel or tank, is also cemployed: this prevents the formation of off-putting hydrogen sulphide characters in the wine. Leaving a wine on lees also encourages malolactic fermentation to commence (see below).
These are a variety of these techniques that the winemakers at Balgownie use in the production of out two Estate chardonnays. As these two wines originated from two very different climates – the Yarra Valley and Bendigo – they employ slightly different winemaking techniques.
Grown in the cooler Yarra Valley, this chardonnay was fermented with wild yeast to add complexity to the finished wine. It spent 11 months on less while maturing in French oak barrels – a combination of 30% new barrels and 70% old barrels. To maintain the freshness of the wine and its crisp acidity, the Yarra Valley Chardonnay did not go through malolactic fermentation.
The warmer climate in Bendigo tends to produce riper and richer fruit that results in a heavier wine. The Bendigo Chardonnay was partially fermented with wild yeast and partially with cultured yeast before spending 11 months on lees. The wine was matured in a combination of new and old French oak barrels. This wine also did not go through malolactic fermentation to preserve the natural grape acidity and freshness.
