Winemaking Philosophy
Today, we have a dedicated team of grape growers and winemakers working together to create truly remarkable wines.
Our winemaking is both uncompromising and intuitive, with each wine handcrafted to reflect its unique origin.
A constant commitment to detail and a steadfast dedication to quality see Petaluma wines setting the standard — now and for decades to come.
This meticulous approach has guided us to cultivate Riesling in the Clare Valley; Cabernet Sauvignon, Merlot, and Shiraz in Coonawarra; Chardonnay in the Piccadilly Valley of the Adelaide Hills; Shiraz from the warm escarpment of Mount Barker; and Sauvignon Blanc from the cool climate of the Adelaide Hills.
Ben Thoman
Ben was born and raised in South Australia. After a career as a project manager and engineer, Ben's passion for wine led him to take a leap of faith. He returned to student life to study winemaking at the University of Adelaide. After completing his formal wine education, he got into research and scale winemaking, and completed a vintage in the Mosel Valley, Germany in pursuit of his love of Riesling.
After more than 15 years in the wine industry, Ben has had a variety of roles that have allowed him to develop his skills in all styles of winemaking. This includes a stint as a sparkling winemaker in Napa, California. Ben enjoys judging wine shows and engaging with consumers as part of his role and development as a winemaker.
From a philosophical perspective, Ben is fascinated by how winemaking combines art and science. Due to his engineering background, he takes a systematic approach to his work in order to ensure that there is enough time for fun and creativity.
Adelaide Hills
The soils of Mount Barker are formed from the underlying micaceous granitic schist geology and are ideal for the vigorous Shiraz variety, producing ripe but elegantly structured wines.
What Makes It Unique?
Soil
Predominantly grey-brown or brown loamy sands with some patches of mostly sandy soils.
Climate
Altitude creates various meso-climates but overall the climate is cool. The region is very hilly with various valleys and sub-valleys and best suited to early ripening varieties.
Rainfall
During the growing season there will be around 260mm of rainfall with a mean temperature of 20.4°c (January)
Varietals
Best known for cool-climate classics like Sauvignon Blanc, Chardonnay and Pinot Noir, and is pushing the case for alternative varieties.
Clare Valley
Planted in 1968. Located 500 metres above sea-level in the eastern hills of the Clare Valley. The slate geology underlying the Hanlin Hill vineyard is perfect for producing the highest quality Riesling. Hard rock creates Riesling, which is invariably characterized by high acidity and slate nuances.
Cool nights and sunny days in the Clare Valley provide ideal conditions for the rich citrus flavours found in Petaluma Riesling. The flinty austerity that the wine maintains is due to the fruits’ high natural acidity.
What Makes It Unique?
Soil
Clare Valley has 11 different recognised soil types. Polish Hill is known for broken slate, while Watervale has limestone in sub-soils.
Climate
Temperatures from 40°C during the day to 1°C at night are common during main ripening months. This region has protection from cooling maritime breeze.
Rainfall
Average growing season rainfall is 232mm with a mean temperature of 22.3°c (January)
Varietals
Celebrated for its Rieslings, the Clare Valley also produces world-class reds, including Shiraz and Cabernet.
Coonawarra
What Makes It Unique
Soil
A flat region famous for its terra rossa soils. Thin iron-oxide based top soil over limestone
Climate
Coonawarra experiences a maritime influence due to upwelling of cold ocean currents at certain times of the year.
Rainfall
Average growing season rainfall is 260mm with a mean temperature of 20.1°c (January)
Varietals
Coonawarra is famed for its age-worthy red wines, most notably its Cabernet Sauvignon.
