Why is Australian wine oversupply worse for red varietals?

Consumer preference globally has been shifting toward white wine, sparkling, and premium alternatives, while Australian production historically skewed toward red varietals, especially Shiraz and Cabernet Sauvignon. In 2024-25, the crush of red varieties increased 20% year on year, widening the mismatch between production and demand just as per-capita alcohol consumption globally continued to fall. Shiraz in particular has excess supply concentrated in South Australia and Victoria, where large-scale production is most difficult to redirect.

How has the China market reopening affected the oversupply situation?

China lifted its tariff restrictions on Australian wine in March 2024, which provided a significant short-term relief valve. In the 12 months to June 2025, Australian wine exports increased 13% in value and 3% in volume, partly driven by China resuming imports. However, the reopening has begun to stabilise rather than accelerate, and exports in the 12 months to December 2025 then declined 8% in value to $2.34 billion AUD. The China reopening helped reduce the inventory peak but has not resolved the structural imbalance between red varietal production and global consumer demand.

What is the stock-to-sales ratio and why does it matter for exporters?

The stock-to-sales ratio measures how many litres are held in national inventory relative to annual export and domestic sales volume. Australia's 10-year average SSR is 1.66, meaning producers historically hold roughly 20 months of forward sales in stock at any given time. At 1.9, the current ratio represents approximately 23 months of supply, which means capital is tied up in inventory for an extra two to three months relative to a balanced market. For an exporter with large bonded warehouse holdings, a sustained elevated SSR translates directly into higher storage costs, greater vintage degradation risk on wine not suited to extended cellaring, and reduced negotiating leverage with importers who know supply is plentiful.

How Do Australian Wine Exporters Manage Oversupply?

Australian wine exporters manage oversupply by segmenting inventory at the varietal and vintage level rather than treating it as a bulk position, then targeting export markets where price-per-litre benchmarks can still absorb surplus volume without collapsing domestic price floors. National inventory as of June 2025 sat at 2.06 billion litres, 15% above the 10-year average, with a stock-to-sales ratio of 1.9 versus a long-run average of 1.66. The most resilient exporters in this environment are those with real-time visibility into which parcels are accumulating relative to contracted forward sales, allowing them to redirect volume toward higher-value markets before the surplus forces below-cost bulk sales.

The Scale of Australia's Current Wine Inventory Position

Australia's wine industry held 2.06 billion litres of inventory as of June 2025, according to Wine Australia's annual production, sales and inventory report. That figure represents a 5% increase from the prior year and sits 15% above the industry's 10-year average. For context, total Australian wine production in 2024-25 was 1.13 billion litres, meaning the country is holding close to two full years of production volume in national stock.

The stock-to-sales ratio (SSR) reached 1.9 in 2024-25, up 4% from the prior year. The 10-year average SSR is 1.66. The gap between those two figures, 0.24 ratio points, represents hundreds of millions of litres of wine sitting in tank and bonded warehouse beyond what a balanced market would carry. That is not a number that normalises quickly through pricing adjustments alone.

The underlying production driver is a varietal mismatch. In the 2024-25 crush, red varieties increased 20% year on year while white varieties rose only 2%. Yet consumer demand globally continues to shift toward white wine, sparkling, and premium alternatives. The Shiraz and Cabernet Sauvignon parcels accumulating in South Australia and Victoria are the most directly exposed to this mismatch, because the export markets that historically absorbed Australian red wine in volume — particularly the UK and China — have both shown declining average price-per-litre for bulk red wine product.

How the Market Correction Is Playing Out

The China market reopening in March 2024 provided temporary relief. In the 12 months to June 2025, Australian wine exports increased 13% in value to $2.48 billion AUD and 3% in volume, reflecting a combination of pent-up demand from Chinese importers and favourable exchange rate conditions. However, that stimulus has faded. In the 12 months to December 2025, exports declined 8% in value to $2.34 billion AUD and 6% in volume to 613 million litres.

The pattern is consistent with other post-tariff market normalisations: initial volume recovery driven by restocking, followed by a return to underlying demand levels. The China market has reopened but it has not grown back to pre-2020 levels, and it is absorbing Australian wine at a measured pace rather than acting as a clearing mechanism for surplus.

The weaker Australian dollar and improving freight conditions from recent years provide some structural support for export competitiveness. But currency support does not solve a varietal composition problem. A South Australian producer with 500,000 litres of 2022 Shiraz in tank at a $4.50 per litre cost of production who can only achieve $3.80 per litre in the current bulk market is not going to be rescued by exchange rate movements within a normal trading range.

Exporters who are navigating this environment most effectively are doing two things differently. First, they are segmenting their inventory at the parcel level rather than managing it as an aggregate volume position. A producer who knows exactly which parcels by vintage, variety, and tank location are contracted forward, which are uncontracted but in active negotiation, and which are genuinely surplus has a materially different set of options than one who knows only their total litres on hand. Second, they are monitoring import demand signals in real time across multiple markets rather than reviewing quarterly export reports.

Why Inventory Visibility Determines the Outcome

The difference between a controlled surplus reduction and a distressed bulk sale is often timing. An exporter who identifies a 60,000-litre Shiraz parcel accumulating against a contracted forward position six months before the contract delivery window can redirect it to a different importer, blend it into a product specification with stronger demand, or renegotiate the delivery schedule before the importer is aware of the pressure. An exporter who surfaces that same situation two weeks before contractual delivery has materially fewer options and typically absorbs a significant price concession to resolve it.

Real-time inventory visibility at the parcel level, connected to contracted forward sales by market and importer, is the operational capability that creates that six-month window. Without it, inventory management defaults to periodic stocktakes that are backward-looking by definition.

The Wine Australia production and inventory data confirms that the oversupply problem is a national one. The resolution of it, for each individual producer and exporter, depends on how precisely they can match their specific parcel mix to the markets where demand currently exists.

What Australian Exporters Should Track in 2026

Three data points are worth watching closely through 2026. The first is the Chinese import trajectory: if China continues to absorb Australian wine at the post-reopening normalised pace, it absorbs surplus volume at a controlled rate. If Chinese domestic economic conditions soften further, that absorption rate could slow.

The second is the southern hemisphere harvest comparison. In 2025, New Zealand's crush increased 32% and South Africa's increased 16%, alongside Australia's 11% increase. Southern hemisphere oversupply is not exclusively an Australian problem, and bulk wine price benchmarks for white varieties in particular are affected by regional harvest outcomes across all three markets.

The third is the Australian domestic market trajectory. Per-capita wine consumption in Australia has been declining alongside the global trend. Domestic sales cannot be expected to absorb the surplus that export channels cannot clear.

For exporters, the practical response to all three of these pressures is the same: know exactly what you have, where it is, what it costs, and which markets have the current capacity to absorb it at an acceptable margin. That is an inventory visibility and demand matching problem. It is solvable.

How Vintaflow helps

Real-Time Inventory Management

Vintaflow's Real-Time Inventory Management gives Australian wine exporters a live view of inventory by parcel, variety, vintage, and bonded warehouse location across multiple markets simultaneously. When stock-to-sales ratios diverge between the domestic and export ledger, the system surfaces the discrepancy in real time rather than at the next monthly stocktake. This allows an export manager to identify a 40,000-litre Shiraz parcel accumulating at a UK importer before it triggers a distressed bulk sale, and redirect volume to a market with stronger current demand. No ERP required: Vintaflow integrates with the warehouse management and freight documentation systems already used in the Australian export supply chain.
