Red grape oversupply in 2026: what the vintage, export and policy numbers say

For several years the story of the Australian wine sector has been too many red grapes and not enough buyers. The 2026 numbers show the industry shrinking to fit — and they also show that a smaller crop has not, so far, fixed prices. Here is what Wine Australia’s latest reports actually say, and what is changing for growers and wineries over the next year.

Vintage 2026: the smallest crush since 2000

Wine Australia’s National Vintage Report 2026, released on 15 July 2026, estimates the national crush at 1.27 million tonnes:

• Down 306,334 tonnes (19%) on 2025, and 25% below the 10-year average of 1.69 million tonnes — roughly 33 million fewer 9-litre cases.
• Reds fell by 243,560 tonnes (29%), the smallest red crush since 2000, and accounted for 80% of the national decrease.
• Whites fell by 9%, lifting their share of the crush to 53%.
• The average purchase value of grapes was $570 a tonne, down 6% on 2025.

Wine Australia attributes the fall to seasonal pressures, including flooding in inland regions, to a deliberate adjustment by the industry to market conditions, and to shifting demand: citing IWSR, it notes that global red wine consumption has been falling about twice as fast as white since 2017.

“There has been no improvement in grape prices, which suggests that demand is still very soft.” — Peter Bailey, Manager, Market Insights, Wine Australia

Prices: no rebound, even with less fruit

By segment, the report shows prices for cool/temperate reds and whites both down 3%, warm inland reds down 1% and warm inland whites down 12%. Wine Australia describes the drop in volume as an “underlying reset” in the tonnage winemakers need — which is a polite way of saying the cut in supply has so far matched the fall in demand rather than overtaken it. It also warns of a risk of over-correction, and notes that the sector lacks reliable data on what is being planted and removed.

Exports and China

China removed its duties on Australian bottled wine from 29 March 2024. Before the duties, in 2019, Australia’s wine exports to China were worth $1.1 billion, and the reopening brought a burst of shipments. That restocking phase is now over. Wine Australia’s export report for the 12 months ended June 2026 shows:

• Export value of $2.30 billion, down 7%.
• Export volume of 598 million litres, down 6%.
• An average of $3.84 a litre FOB, down 1%.
• Lower shipments to mainland China, which Wine Australia puts down to the end of post-tariff restocking and subdued underlying consumer demand.

In short, China is open again but it has not become the outlet for surplus red that some hoped for. With export volumes still falling, the adjustment has to come mostly from the vineyard side.

What is changing in policy

Three changes are worth tracking if you grow or buy grapes:

• A mandatory code of conduct for winegrape purchases comes into effect from 1 January 2027. It covers dealings between growers and large winemakers and aims for more transparency, more consistent trading terms, more certainty on price deductions and dispute resolution, and key financial information for growers. Wine Australia says it will be administered by the ACCC. Consultation on the exposure draft closed on 9 October 2026, so check the final text before vintage 2027 contracts.
• The Wine and Other Legislation Amendment Bill 2026, which amends the Wine Australia Act 2013 to support the code and lets Wine Australia conduct or arrange industry surveys, passed both Houses of Parliament on 10 September 2026.
• A National Vineyard Register is being built. Wine Australia says the platform will launch in late 2026 and it will take at least 12 months to record all plantings. Growers will enter variety, area, location and whether vines are bearing, with year planted, clone and rootstock optional; ownership details are kept confidential.

Separately, the Wine Australia Regulations 2018 are due to sunset on 1 April 2028 and are under review, so the rules behind labelling and export will be looked at again in the next 18 months.

What it means on the ground

None of this tells an individual grower whether to pull a block of Shiraz. What the data does make clear is that decisions are being made with thin information — Wine Australia’s own vintage survey is voluntary and cannot see fruit left unpicked. A few practical steps follow:

• Know your planted area, variety, age and yield by block. You will need it for the National Vineyard Register anyway, and it is the starting point for any decision to graft, replant or remove.
• Know your real cost per tonne and per litre by block and by wine, not just the winery average, so you can tell which blocks pay their way at $570 a tonne or less.
• Keep supply records tidy: tonnes delivered, dates, varieties and GIs, and the terms agreed. Under a mandatory code, documented terms and deliveries are what a dispute will turn on.
• Watch the white/red balance in your own sales. The national crush has already tipped to 53% white.

GrapeFlow keeps the block-level side of this together — variety, area and planting year for each block, maturity samples, intake by block and the lots each block produced — so the information is to hand when you need to report it or make a call on a vineyard. It does not submit data to Wine Australia, the National Vineyard Register or any survey.
