Victoria’s grape growers faced an array of difficulties during the 2024 vintage season, as outlined in this year’s vintage report. While some varietals managed to shine despite the adversities, the overall narrative paints a picture of resilience amidst trying circumstances.
The period from September to November initially provided a semblance of stability, only to be disrupted by heavy rainfall in December and January. With precipitation levels reaching up to 70mm, this deluge significantly impacted the crucial two-week flowering phase, setting the tone for ensuing challenges.
Vineyards situated downhill had a slight advantage, navigating the inclement weather more adeptly compared to their uphill counterparts. However, the latter faced an uphill battle against wet and humid conditions, which fostered the proliferation of downy mildew and bacterial inflorescence necrosis. Notably, high-elevation vineyards around Main Ridge bore the brunt of these conditions, suffering substantial yield losses.
Despite the setbacks, pockets of resilience emerged in regions such as Tuerong, Balnarring, Moorooduc, and lower, northerly vineyards, which managed to maintain commendable yields and concentration.
The aftermath of heavy rainfall gave way to a seven-week dry spell, commencing at veraison, the grape ripening phase. This prolonged period sans precipitation, coupled with two notable heat waves, contributed to elevated levels of titratable acidity and pH. Winemakers now face the task of delicately balancing these factors during the vinification process.
The accelerated ripening process prompted an earlier-than-usual harvest, commencing around 16 February instead of the customary 1 March start date. Despite the expedited timeline, reports indicate minimal crop damage, a testament to growers’ adaptability in navigating adverse conditions.
Olivia Barrie, CEO of Mornington Peninsula Wine, offered insights into the silver linings of the 2024 vintage, highlighting the pressure to expedite harvest as a catalyst for exceptional outcomes. “Chardonnay stands out as a star performer, boasting impressive colour, intensity, and enticing flavour profiles,” she remarked. Additionally, Barrie noted the enriching contribution of pinot noir, which added layers of complexity to the vintage.
While acknowledging the resilience demonstrated by various varietals, Barrie emphasized the significance of diversification in mitigating risks associated with vintage and climate volatility. This sentiment underscores the industry’s ongoing efforts to adapt and innovate in the face of unpredictable weather patterns, ensuring the continued success of Victoria’s viticultural landscape.
