GRIFFITH, Australia, March 9 (Reuters) - Millions of

vines are being destroyed in Australia and tens of millions more

must be pulled up to rein in overproduction that has crushed

grape prices and threatens the livelihoods of growers and wine

makers.

Falling consumption of wine worldwide has hit Australia

particularly hard as demand shrinks fastest for the cheaper reds

that are its biggest product, and in China, the market it has

relied on for growth until recent years.

The world's fifth largest exporter of wine had more than two

billion litres, or about two years' worth of production, in

storage in mid-2023, the most recent figures show, and some is

spoiling as owners rush to dispose of it at any price.

"There's only so long we can go on growing a crop and losing

money on it," said fourth-generation grower James Cremasco, as

he watched clanking yellow excavators strip out rows of vines

his grandfather planted near the southeastern town of Griffith.

About two-thirds of Australia's wine grapes are grown in

irrigated inland areas such as Griffith, its landscape shaped by

vine-growing techniques brought by Italian migrants arriving

around the 1950s.

As major wine makers such as Treasury Wines and

Carlyle Group's Accolade Wines refocus on more expensive

bottles that are selling better, the areas around Griffith are

struggling, with unpicked grapes shrivelling on vines.

"It feels like an era is ending," said Andrew Calabria, a

third-generation vineyard owner and wine maker at Calabria

Wines.

"It's hard for growers to look out the back window and see a

pile of dirt instead of vines that have been there as long as

they've known."

Nearby, the remains of 1.1 million vines that once comprised

one of Australia's largest vineyards were piled in heaps of

gnarled and twisted wood as far as the eye could see.

Red wine has suffered the most. In regions like Griffith,

prices of the grapes going into it fell to an average of A$304

($200) a ton last year, the lowest in decades and down from

A$659 in 2020, data from industry body Wine Australia show.

The government, which forecasts lower prices again this

year, said it recognises the significant challenges facing

growers and is committed to supporting the sector, though many

growers say it can do more.

Cremasco said some of his red grapes sold for little more

than A$100 a ton.

To balance the market and lift prices, up to a quarter of

the vines in areas such as Griffith must be pulled up, said

Jeremy Cass, head of Riverina Winegrape Growers, a farmers'

group there.

That would destroy more than 20 million vines across 12,000

hectares (30,000 acres), Reuters calculations based on Wine

Australia data show, or about 8% of Australia's total area under

vine.

Growers and winemakers in other regions have also been

pulling out vines.

"If half the vines in Australia were ripped out, it still

might not solve the oversupply," said a wine maker in Western

Australia.

Still, many growers unwilling to pull up vines are losing

money while hoping for the market to turn around.

"It's chewing up wealth," said KPMG wine analyst Tim

Mableson, who estimates that 20,000 hectares (49,000 acres) of

vines need to be taken out nationwide.

GIVING IT AWAY

Health concerns are prompting consumers worldwide to drink

less alcohol and when they do drink wine, they pick pricier

bottles.

Chile, France and the United States are among the other

large wine producers also grappling with oversupply, with even

prime areas such as Bordeaux uprooting thousands of hectares of

vines.

When China blocked imports during a political dispute in

2020, Australia lost its biggest wine export market by value.

And unlike Europe, it offers farmers no financial aid to help

them destroy vines and excess wine.

Even though China is expected to allow imports again this

month, that will not mop up the glut, as demand there has fallen

much more rapidly than elsewhere.

Wine sold for less than A$10 a litre - most of it made from

grapes grown in areas like Griffith - accounted for two-thirds

of the value of Australian wine exports worth A$1.9 billion in

the year to December 2023, Wine Australia says.

Some areas are faring better, such as Tasmania and the Yarra

Valley in Victoria, which produce more white wines and lighter,

more expensive reds that are growing in popularity.

But across Griffith there are clusters of metal storage

tanks, each holding thousands of litres.

"Everyone is trying to clear wine," said Bill Calabria,

Andrew's father, adding that wineries were "all but giving it

away" to make room for the incoming vintage.

Many growers are turning to citrus and nut trees instead.

Cremasco hopes for greater profits from the prune trees he

is planting in his grubbed-up acreage, while GoFARM, a

corporation, is putting in more than 600 hectares (1,500 acres)

of almonds nearby, also replacing vines.

"There'll be no next generation of family grape growers,"

Cremasco added. "It'll be all big corporates, and all the local

young guys will be working for them."
