Croser & Bizot: a family vision in Wrattonbully

Wrattonbully, in South Australia’s Limestone Coast region, is home to two powerhouse wine families from opposite sides of the world now entwined by marriage. Sarah Ahmed chats with Australian wine legend Brian Croser and his son-in-law Xavier Bizot of the Bollinger Champagne house, and tastes through some recent releases.

Bringing impetus to Croser’s bold pursuit of distinguished sites – first at Petaluma then Tapanappa – the Bizots have helped engineer a new Australian fine wine landscape in both Wrattonbully and Adelaide Hills. One which now also finds expression in Terre à Terre, the label Bizot and wife Lucy Croser established in 2008.

How did these families from opposite sides of the world attract, and how do Tapanappa and Terre à Terre compare?

California dreaming

The meeting of minds between Brian Croser and Christian Bizot drew inspiration from California. It was here Croser studied his masters in viticulture and oenology at UC Davis (and fell in love with Chardonnay). Between 1972 and 1973 he was one of the last to study under such legendary professors as AJ Winkler and Maynard Amerine.

Californian viticulturalists had been using Winkler’s growing degree days system (matching varieties to climate) for some time. It underpinned the state’s nascent but precocious boutique wine industry which, in 1976, famously triumphed over benchmark Burgundy and Bordeaux in the Judgement of Paris.
The Winkler index informed Croser’s ‘belief in the expression of distinguished sites through the choice of suited variety and appropriate planting regimes’. He says this belief ‘has never wavered and has been reinforced continually’ in his 50-year career.

Tiers Vineyard

Armed with his ‘golden rule’ for matching Australian sites to Burgundian and Bordelais grapes – ‘close to a metre of rain a year and then a cool climate, at altitude’ – Croser located his first brand, Petaluma, at 450m in the Adelaide Hills’ highest, wettest, coolest point: the Piccadilly Valley.
In 1979, he planted his Tiers Vineyard (‘Adelaide Hills’ first 20th century vineyard’) to Chardonnay at 3,175 vines per hectare. This was revolutionary, compared with Australia’s then typical 1,000-1,500 vines/ha.

Croser was aiming for a style ‘somewhere between Chevalier-Montrachet and California’. In 2003, when he replanted a parcel to Burgundy clones at 4,444 vines/ha, Chevalier-Montrachet ‘my mind’s eye inspiration’.

The French connection

When Croser visited Champagne in 1984 to find a partner for Petaluma’s ‘Croser’ sparkling wine project, he discovered that Christian Bizot was equally receptive to California’s application of science in pursuit of terroir.

The following year Bollinger not only became Petaluma shareholders, but also partnered with British brewers Whitbread and Tuscany’s Antinori, to plant the pioneering Atlas Peak Vineyard at altitude in the Napa Valley.

In 1995, Bizot acquired a Piccadilly Valley site at 550m for sparkling production. With Croser’s guidance, it was planted at similar density to Tiers, with multiple Chardonnay clones and a small block of Pinot Noir.
Following Petaluma’s takeover by Lion Nathan in 2001, Croser and Bizot founded Tapanappa a year later, cutting in a third partner, the Cazes family of Lynch-Bages in Pauillac.

Rather than planting from scratch (or acquiring a vineyard in Coonawarra, where Petaluma had focused its Bordeaux blend ambitions), Tapanappa acquired the Koppamurra Vineyard in Wrattonbully, renaming it Whalebone Vineyard.

Located on South Australia’s Limestone Coast, Wrattonbully shares Coonawarra’s famously well-drained terra rossa over (older) limestone soil. But Croser observed that Wrattonbully’s cool but less windy conditions ‘bridged St-Emilion and Tain l’Hermitage’.

Being sufficiently maritime to ripen Bordeaux varieties but also continental enough for Shiraz, the Whalebone Vineyard became a seat of ambition for that iconic Australian red blend of Cabernet-Shiraz. Initially to supply Tapanappa with fruit, Croser also planted the vineyard next to Whalebone in 2004. His daughter Lucy and husband Xavier named it Crayères, and managed it from France for a year before settling in Australia in 2005.

From France to Wrattonbully

Following the 2008 global financial crisis, the young Bizots were faced with a difficult decision, as it became obvious that Tapanappa could not absorb all the harvest from the Crayères Vineyard.
Deciding to take on both management and fruit and make their own wine, the couple founded Terre à Terre.

Xavier’s country of origin may have informed the name of the vineyard and brand, but not the wines. With ‘a fondness’ for Cabernet-Shiraz, the former lawyer says he now feels at ease in his RM Williams boots.

The Bizots vision for Terre à Terre’s Daosa sparkling wines is ‘radically different’ from Champagne or any of Australia’s early-picked Champagne wannabes. ‘Our climate, our sunshine, our soils make fruitier and more approachable wines,’ asserts Xavier, ‘so they are distinctively Australian and all the better for it.’

Lucy Croser and Xavier Bizot

Sourced exclusively from the Piccadilly Valley vineyard his father planted in 1995 (which Xavier and Lucy now own), Daosa’s full-bodied Blanc de Blancs – a Platinum winner at the 2020 Decanter World Wine Awards – is a testament to the quality.

Terre à Terre’s finely honed, perfumed Wrattonbully reds evoke stereotypical Old World descriptors, versus Tapanappa’s big-boned, densely concentrated, more savoury New World style.

This is particularly evident in Terre à Terre’s Crayères Cabernet Franc, planted from Whalebone cuttings. This might be expected, given Whalebone’s vines are 30 years older and Terre à Terre also uses large-format oak foudres.

While pointing out ‘how elegantly and freshly’ Tapanappa’s Whalebone 2004, 2006 and 2008 Cabernet Francs have aged, Croser nevertheless has ‘absolutely no doubt’ that Crayères’ precocious refinement reflects his higher- density planting regime of 4,444 vines/ha.

It was a regime also implemented at the Tiers Vineyard and Foggy Hill – Croser’s Pinot Noir vineyard in Parawa, the highest point of the Fleurieu Peninsula.

In the family

Spelling out the benefits of high-density planting for ripening in Australia’s cooler climates, Bizot explains it ‘devigorates’ and, by increasing the canopy per hectare, improves fruit spread and sunshine exposure.
Croser forecasts that in 10 years’ time ‘Crayères will be the equivalent of or better than Whalebone, with the same density and same seriousness of tannin, but it will always retain its more floral, juicy fruit element.’

Does it annoy him that Crayères is no longer a Tapanappa vineyard? ‘No,’ he insists. ‘It’s in the family. There are separate ownership structures, but the ambition of everybody is to make a success out of all our assets.’

Foggy Hill Vineyard

And it’s not just Croser’s daughter Lucy and husband Xavier who are part of the wider Croser winemaking family. Sam Barlow, the husband of his youngest daughter, Caroline, manages the Tapanappa winery where both labels are made and bottled.

In 2014, the Croser family bought out Bollinger and the Cazes family, taking full ownership of Tapanappa.
Reflecting on the ‘immense’ importance of the two families’ roles during his ‘long and mostly lonely battle’ to improve and promote Australian fine wine, Croser describes Christian Bizot and Jean-Michel Cazes as ‘revered mentors’.

Their French perspective gave him confidence to continue on the ‘terroir pathway’ that he discovered as a student in California.

Realising the vision

Despite Croser’s successes, it’s been a rollercoaster ride. ‘Like vines, winemakers mature with time,’ he says wryly.

Reflecting on his vision for Tiers Vineyard Chardonnay all those years ago, Croser says that while he can identify a similar intensity and delicacy of power between Tiers Chardonnay, Chevalier-Montrachet and top California Chardonnay, he has come to appreciate the merits of being ‘totally and joyfully different’.
‘Tiers is an expression of where we are, rather than a copy of somewhere else in the world,’ he says.

The justification for all the ‘hard yards’, says Croser, rests in the family’s desire to be part of the journey. But how his vision will ultimately be achieved he says, ‘will be more and more in Xavier’s capable hands’.
While the pair avidly talk about the potential of new, yet-to-be-discovered distinguished sites in Victoria and Tasmania, Bizot is focusing closer to home, excited by the prospect of working with more mature Piccadilly Valley vineyards, planted by Croser. ‘It’s a privilege,’ he beams.
