Tapanappa

Brian Croser is one of the most influential figures in modern Australian wine. After studying at Roseworthy Agricultural College and the University of California Davis under Maynard Amerine, he founded Petaluma in 1976 and built it into one of the country's most respected cool-climate wineries, particularly for its Tiers Chardonnay and the Croser sparkling wine. Croser was also a founding chairman of the Winemakers' Federation of Australia and a founding member of the Australian Wine Research Institute, and he received the Order of Australia for his contributions to the industry. Petaluma was sold to Lion Nathan in 2001, and Croser stepped away from the operational leadership over the following years. In 2003 he established Tapanappa as a new boutique enterprise, initially in joint venture with two storied European partners: the Cazes family of Chateau Lynch-Bages (the famous Pauillac fifth growth estate) and the Bollinger Champagne house. The international partnership reflected the global respect Croser had earned over three decades. The venture has since reverted to Croser family ownership, with daughter Lucy Croser playing an increasing role in the operations.

The Tiers Vineyard sits in Piccadilly Valley at the highest elevations of the Adelaide Hills, approximately 500 metres above sea level. Brian Croser planted the site in 1979 as one of the earliest premium Chardonnay vineyards in the Adelaide Hills, and the Petaluma Tiers Chardonnay built from this site became one of the benchmark cool-climate Australian Chardonnays through the 1980s and 1990s. Following Petaluma's sale, the Tiers Vineyard transitioned to Tapanappa's exclusive use, and the Tapanappa Tiers Chardonnay now carries the direct lineage of the original Croser Tiers programme. The site is defined by free-draining soils on Mount Lofty Ranges fractured rock substrate, cool nights, and a late ripening pattern that preserves natural acidity. The Chardonnay is whole-bunch pressed, cold-settled, fermented in French oak with native yeast on the premium parcels, and aged extensively on lees in a regime that has remained consistent with Croser's classical winemaking approach for over four decades.

• Whole-bunch press, cold settle, native yeast French oak fermentation, extended lees ageing; consistent Croser winemaking approach for 40+ years

The Whalebone Vineyard sits in Wrattonbully, the Limestone Coast region immediately north of Coonawarra. The site is planted on the same terra rossa over limestone formation that defines Coonawarra: a shallow red iron-rich clay loam over hard cap rock and underlying limestone, with the soft soil over hard rock combination that gives Wrattonbully and Coonawarra Cabernet its characteristic structure and longevity. The vineyard takes its name from whale fossils discovered in the underlying limestone, a reminder of the marine origin of the South East South Australia limestone formation. Plantings include Cabernet Sauvignon, Cabernet Franc, Merlot, and Shiraz, with the Cabernet-led wines representing the Tapanappa expression of the Limestone Coast terra rossa terroir. The flagship Whalebone Vineyard Cabernet Shiraz blend honours the classic Australian red blend tradition while drawing structural elegance from the Wrattonbully site. Single-variety Whalebone Cabernet Sauvignon is also produced in selected vintages.

The Foggy Hill Vineyard sits on the southern Fleurieu Peninsula, approximately 7 kilometres from the Southern Ocean. The site is one of South Australia's southernmost mainland Pinot Noir plantings, planted on schistose and slate-derived soils with strong maritime moderation from the cool southern coastal influence. The cool maritime climate, low yields, and acidic schistose soils suit the production of Burgundian-style Pinot Noir with restrained alcohol, vibrant acidity, fine tannins, and savoury aromatic complexity. The Foggy Hill Pinot Noir has become one of Tapanappa's most acclaimed wines and one of the most respected mainland South Australian Pinot Noirs, distinguishing the Fleurieu Peninsula as a serious Pinot Noir terroir alongside the Adelaide Hills. Croser has long argued that mainland South Australia is capable of world-class cool-climate Pinot Noir given the right site selection, and the Foggy Hill bottling has done as much as any single wine to make that case.

• Foggy Hill Vineyard: southern Fleurieu Peninsula, ~7 km from the Southern Ocean; among South Australia's southernmost mainland Pinot Noir plantings
• Schistose and slate-derived soils; cool maritime climate with strong moderation from the Southern Ocean
• Burgundian-style Pinot Noir with restrained alcohol, vibrant acidity, fine tannins, savoury aromatic complexity
• Distinguished the Fleurieu Peninsula as a serious mainland Pinot Noir terroir alongside the Adelaide Hills

Tapanappa wines carry Brian Croser's hallmarks of acid retention, extended lees ageing, classically structured Burgundian and Bordeaux influences, and measured oak in support of fruit rather than dominating it. The Tiers Chardonnay is the most direct expression of the Croser winemaking lineage: whole-bunch pressed, cold-settled, native yeast fermentation in French oak (with controlled new oak), extended lees ageing without battonage, and bottling at moderate alcohol with vibrant natural acidity. The Whalebone wines follow a Bordeaux-influenced approach: traditional fermentation, French oak ageing, classical structure built for cellaring over 15 to 25 years. The Foggy Hill Pinot Noir takes a Burgundian model: destemmed (with some whole bunch in cooler vintages), native yeast in small open vessels, gentle extraction, French oak ageing with modest new oak. Across the range, the wines emphasise place-specific expression rather than producer-style imprint, with each single-vineyard cuvee designed to express the terroir of its source. Production is intentionally limited; the wines are distributed via mailing list and select fine wine retailers in Australia and key export markets.

• Croser winemaking hallmarks: acid retention, extended lees ageing, classical Burgundian and Bordeaux influences, measured oak in support of fruit
