About Us

Head west out of Melbourne towards the Great Ocean Road, and just before Colac you’ll pass through a region where the Otway foothills meet the volcanic lake and plain country known as Irrewarra.

It’s here that our story begins – and where it continues to thrive. This land is home to our family’s heritage as well as our renowned artisan bakery.

Irrewarra is known for producing Victoria’s most-loved sourdough and Australia’s finest granola. We have been using traditional methods and simple, natural ingredients for more than 25 years.

It’s a daily pleasure to provide lovers of fine food across Australia with authentic, high-quality sourdough bread, crunchy granola, quintessential Australian Anzac biscuits and festive treats.

Everything we produce is an expression of quality and craftsmanship – and we know that you can taste the difference.

Lawyers Turned Bakers

Like many great ideas, the Irrewarra story grew out of personal passions and a life watershed moment.

After years spent building our respective law careers in the big smoke of Melbourne, and time on the family farm, we reached a turning point in our lives.  We had spent some time in the 1990s experiencing a particularly memorable wine vintage in Burgundy France, before starting our family, and teaching ourselves how to make sourdough bread at home.

So on New Year’s Day 1999 we asked ourselves the question – what if we turned our passion for baking and winemaking into a business?

A year later, it was happening: in the summer of the new millennium, we started supplying hand-cut, hand-moulded, naturally fermented loaves using our home-nurtured sourdough culture (started in 1995 when our son Jack was born) to a small number of retailers along Victoria’s Great Ocean Road and prepared to plant a vineyard the following year.

After years spent building our respective law careers

We might have since outgrown our bakery in the stables, but we still bake on-site at Irrewarra in a new purpose-built building, set among the farms, fields and freshwater lakes of the former Irrewarra Estate.

We said goodbye to the suits, briefcases and the relentless traffic of Melbourne, and to the family farm west of Geelong, and welcomed aprons, early starts and a new pursuit of quality in both ingredients and breadmaking craft. We set up our home and business on a patch of land in the Victorian Western District farming region that had a deep connection to our family – located at Irrewarra was the Calvert family ancestral land, first settled four generations ago by Scots John Calvert and Jane Murray. The run-down former stables was a perfect restoration project, and we built our small bakery in a wing of the historic building.

And so, Irrewarra Sourdough Bakery was born. The following year Irrewarra Vineyard took root.

For our family and our broader team of bakers and craftspeople, the pursuit of quality continues today. We pride ourselves on our signature long-ferment sourdough breads, our artisan granola range, Anzac biscuits and festive baked goods. The vineyard we passed onto award winning winemakers, By Farr, to make the sublime Irrewarra Wine since 2010.

We outgrew our bakery in the stables, eventually building a new purpose-built 2000m2 bakery, set among the fields of the former Irrewarra Station.

Today our bread reaches 28,000 Victorian homes weekly, and our granola and biscuits are enjoyed by many more people nationally. Our iconic products are now much-loved and sought-after among lovers of quality artisan food – and it’s with this knowledge we feel satisfied that all those years ago, we made the right choice: to pursue our vision of quality and excellence, and turn our bread and wine passion into a reality.

Heritage Timeline

Five generations past and Irrewarra and the Calvert family roots are deeply embedded in the Colac area as their legacy continues to grow.

The Calvert family acknowledges that the land at Irrewarra was taken from the Gulidjan-Kolakngat tribe in the name of the British Crown and no compensation was paid. We recognise the then traditional owners of the Irrewarra land.

1842 — John and Jane Calvert
Scotsman John Calvert purchases a tract of land near Colac, Victoria, and names it Irrewarra, a local Indigenous word meaning ‘long spear throw’. Within three years, John and Jane had established a homestead, stables and woolshed for their thriving Merino sheep farm.

1880 — Irrewarra Station Divided
Irrewarra was divided into four properties for the second generation of Calverts – Irrewarra, Dreeite, Gnarwyn, Warrowie. John II receives Irrewarra and builds Irrewarra House. Here he and his wife, Margaret Chirnside, grow wheat, grapes, grazes sheep and cattle and run five share-farm dairies.

1920s - World War I
Following World War I, parts of the original Irrewarra Estate are sold to the government and redistributed as soldier settlements to returned servicemen. The 1842 homestead and the five share-farmed dairies form some of the soldier settlement farms.

1992 - A Seed is Sown
With a passion for food and wine, fifth generation John Calvert, and Bronwynne Roberts leave their legal jobs in Melbourne to travel to Burgundy, France to do a vintage. It is here that the two lawyers develop a deep appreciation for fine wine and bread.

1995 — The Start of the Starter
John and Bronwynne’s son, Jack, is born and whilst at home they started a sourdough starter in their kitchen using a recipe from the Natural Tucker Bread Book. Two simple ingredients – flour and water – mixed in a bowl and left to ferment for three days. It is during this time their sourdough journey began. In 1998 their daughter Georgina is born and they continue teaching themselves how to bake bread at home with their now established sourdough starter culture that still endures today.

2000 — A New Millenium, a New Career
On New Year’s Day 1999, John and Bronwynne asked themselves: what if we moved to the county and turned our passion for sourdough bread into a business? By January 1, 2000 they had refurbished the stables at Irrewarra and started supplying hand-cut, hand-moulded, naturally fermented sourdough loaves to a small number of retailers along Victoria’s Great Ocean Road.

2001 — Establishing Irrewarra Vineyard
Inspired by their vintage in Burgundy, John and Bronwynne plant a 10-acre vineyard of chardonnay and pinot noir on their property, to produce fine, cool climate wines from unirrigated vines. In 2015, after many unexpected years of drought, the first bottles of Irrewarra wines were released, made by By Farr Winery.

2003-10 — Irrewarra Café
The award-winning Irrewarra Sourdough Café is established in Geelong, proving popular with locals and tourists alike. A signature development from the café is a popular granola, which is introduced into the core Irrewarra range. Anzac biscuits and Panforté followed suit.

2012 — Artisan Granola Prevails
Taken to court by cereal giant Sanitarium over the use of the word ‘granola’, John and Bronwynne successfully defend their case. The reputation of Irrewarra granola as Australia’s best artisan granola continues to grow.

2018 — The New Bakery
With production now having outgrown the stables bakery and Colac bakery, a large purpose-built bakery is established at Irrewarra, designed in the Australian woolshed vernacular. The 2000m² production facility enabled further expansion for the Irrewarra brand.

2021 — Doongara Rewilding
A 100-acre historic site property is purchased in nearby Cressy, situated along the Woady Yaloak River. A significant environmental regeneration effort begins: the Irrewarra-Doongara Rewilding Project, restoring the Red Gum lined river banks, billabongs and native grasslands, and eventual creation of a native bird sanctuary.

2022 — Thwaites Bakery, Colac
John and Bronwynne acquire the former Thwaites Bakery site in Colac’s main street, with a vision to expand their biscuit production and open a local retail bakery. A Colac institution, Thwaites Bakery had been baking bread for over 100 years.

2023 — Irrewarra Murray Street
The production of Irrewarra's biscuit line begins at Irrewarra Murray Street, previously Thwaites Bakery. The award-winning biscuits are also now housed in custom recyclable 'bag-in-box' packets.
