Pierro

Pierro was established in 1979 by Dr Mike Peterkin, a Perth-based medical doctor who had pursued formal oenology training at Roseworthy Agricultural College (Australia's most prestigious wine-education institution, located in Adelaide). Peterkin's connection to Margaret River was familial as well as scientific: he married Shelley Pannell, the daughter of Bill and Sandra Pannell of Moss Wood (Margaret River's second wine estate, founded 1969), making Peterkin part of the founding-era Margaret River wine family directly. Shelley Pannell is the sister of Stephen Pannell, who later founded SC Pannell in McLaren Vale. Peterkin planted the Pierro vineyard on the south bank of Willyabrup Brook in the Wilyabrup sub-region, immediately adjacent to the Moss Wood and Cullen estates, and the boutique scale of Pierro (kept deliberately small across its history) reflects Peterkin's quality-over-quantity philosophy. The estate has remained family-owned and operated across more than 45 years, with Peterkin continuing to practice medicine as a GP one day per week (typically Fridays) alongside winery management.

• Mike Peterkin married Shelley Pannell (daughter of Bill Pannell of Moss Wood); son-in-law of Margaret River's second founding family
• Brother-in-law of Stephen Pannell of SC Pannell in McLaren Vale; deeply connected to the founding Pannell winemaking family
• Family-owned and boutique across more than 45 years; Peterkin continues to practice medicine as a GP one day per week

Pierro Chardonnay is the estate's flagship and is widely considered Margaret River's premier Chardonnay specialist bottling, competing at the highest tier of Australian Chardonnay alongside Leeuwin Art Series, Vasse Felix Heytesbury, Cullen Kevin John, Giaconda, and Bindi. The wine is built on a combination of the Mendoza clone (a Western Australian-favoured Chardonnay clone with small bunches and concentrated fruit) and the Gingin clone (the Margaret River-adapted clone that defines much of the region's Chardonnay programme), with Peterkin's medical-precision approach to winemaking producing a Chardonnay style that is restrained, structured, and built for cellaring. The wine has received multiple 95-plus and 97-plus scores from James Halliday across decades, and aged Pierro Chardonnay regularly outperforms much younger vintages, developing honey, toast, and complex texture while retaining the original acid backbone. Pierro Chardonnay is one of Margaret River's defining white wines and a fixed reference point in Australian Chardonnay discussions, despite the boutique production volumes that make the wine relatively allocated.

• Pierro Chardonnay: Margaret River's premier Chardonnay specialist bottling; competes at the top tier of Australian Chardonnay
• Built on Mendoza clone (small bunches, concentrated) and Gingin clone (Margaret River-adapted)

• Restrained, structured, age-worthy style; cellars 15 to 20+ years developing honey and toast complexity

Pierro made two foundational pioneering contributions to Margaret River that have shaped the region's broader practice. First, Peterkin established the first high-density vineyard planting in Margaret River, with vine density running from 4,000 to 5,500 vines per hectare (well above the regional norm of 1,500 to 2,500 vines per hectare at the time of planting). High-density planting was adopted from Burgundian and Bordeaux models and stresses individual vines through root-zone competition, producing smaller berries and more concentrated fruit. Pierro's high-density success directly influenced subsequent Margaret River plantings. Second, Pierro pioneered Australia's first Semillon-Sauvignon Blanc blend, the LTC (variously named Late Trellised Chardonnay reflecting Peterkin's vineyard trellising experiments, or Les Trois Cuvees, depending on the era and label). The LTC pre-dated and inspired the broader Margaret River Sauvignon Blanc-Semillon blending tradition that Cape Mentelle and others subsequently popularised, making Pierro a foundational influence on the region's signature white blend. Total production at Pierro remains boutique, with approximately 20 different wines produced from 9 grape varieties.

• First high-density vineyard planting in Margaret River: 4,000 to 5,500 vines per hectare; directly influenced subsequent Margaret River plantings
• Pioneered Australia's first Semillon-Sauvignon Blanc blend, the LTC (Late Trellised Chardonnay/Les Trois Cuvees)
• LTC pre-dated and inspired the broader Margaret River Sauvignon Blanc-Semillon blending tradition
• Boutique scale: ~20 wines from 9 grape varieties; deliberately small production reflecting quality-over-quantity philosophy

Beyond the Chardonnay flagship and the LTC, Pierro produces a Bordeaux-style red wine programme led by the Pierro Cabernet Sauvignon-Merlot blend, which applies the same medical-precision winemaking discipline that defines the Chardonnay. Red wine production at Pierro includes meticulous grape sorting at both bunch and berry level, producing wines with structure, dark-fruit purity, and cellar-worthy depth. The estate also produces varietal Pinot Noir, Shiraz, Sauvignon Blanc, Semillon, Chenin Blanc, Riesling, and Viognier across small-volume releases, reflecting Peterkin's interest in viticulture experimentation as much as commercial production. The Pierro cellar door at Wilyabrup is a quiet, low-key destination compared to the larger Margaret River wineries, reflecting the boutique character of the estate. Pierro's status as one of Margaret River's most respected boutique producers and one of the founding-era estates (alongside Vasse Felix 1967, Moss Wood 1969, Cape Mentelle 1970, Cullen 1971, and Leeuwin 1973) makes it an essential reference point in the region's history despite its smaller production scale.

Pierro's vineyards sit on the north-facing south bank of Willyabrup Brook within the Wilyabrup sub-region of Margaret River, immediately adjacent to Moss Wood and Cullen Wines (the Pannell and Cullen estates that founded Wilyabrup as Margaret River's first concentrated vineyard cluster). The Wilyabrup terroir at Pierro is defined by moderately deep laterite gravel soils interspersed with granite, sitting over ancient base rock with friable pink clay merging into a shattered rock layer below. The maritime Mediterranean climate, moderated by cooling Indian Ocean breezes approximately 4 kilometres west, produces warm summer days and cool evenings that preserve natural acidity while allowing full phenolic ripeness across the long even growing season. The north-facing aspect on the south bank of Willyabrup Brook maximises sun exposure during the growing season. Mike Peterkin's family legacy extends beyond his own winemaking: as the son-in-law of Bill Pannell of Moss Wood and brother-in-law of Stephen Pannell of SC Pannell, Peterkin sits at the centre of one of Australia's most accomplished multi-generational wine families, spanning two of the country's most important wine regions (Margaret River and McLaren Vale).
