In the sun-baked landscape of Western Australia’s Wheatbelt, an ancient Persian preservation technique is being reborn, creating Australia’s first commercially produced black limes. The Trethewey family have spent over two decades perfecting their craft, driven by genuine curiosity and an unwavering commitment to sustainable farming. Our creation, Australian Black Limes, represents far more than just another agricultural product—it embodies a philosophy that honors hands-on craftsmanship and deep respect for the natural world.
What happens when ancient Middle Eastern traditions meet modern Australian innovation? The answer lies in the meticulous artisanal techniques that begin on their off-grid, solar-powered farm in Wanerie. Every sun-kissed green lime undergoes a careful transformation through brief brining and slow age drying, creating a bold, smoky ingredient that carries remarkable citrus complexity. This process reflects decades of horticultural experience and an intimate connection to the land that sustains them.
The Tretheweys have established themselves as Australia’s first producers of black limes, quite possibly marking a first for the entire Southern Hemisphere. Their approach prioritizes meaningful production over mass manufacturing, creating a product that resonates with professional chefs, restaurant owners, gourmet home cooks, and health-conscious consumers. Each black lime tells a story of resilience, family values, and the creative spark that emerges when traditional methods adapt to contemporary sustainable practices.

The Story of Australian Black Limes: From Vision to Reality

The Trethewey family’s venture into black lime production began with a simple suggestion from a neighbor. After spending over two decades in horticulture around Gingin, Western Australia, Veronica and Grant Trethewey faced the ongoing challenges of traditional fruit farming. Financial sustainability remained elusive, despite their extensive experience and dedication to quality produce.
That pivotal conversation about black limes opened an entirely new chapter. The family recognized an opportunity to adapt ancient Persian loomi techniques to Australian conditions, creating something both distinctive and authentic. Their vision extended beyond mere profit—they wanted to establish a sustainable farming operation that could be passed down to their children while contributing meaningfully to Australia’s culinary landscape.
Can passion and persistence really transform a simple fruit into something extraordinary? The Tretheweys proved this possible through years of experimentation and refinement. Operating entirely off-grid with solar power, they developed hands-on methods that guide each lime through careful harvesting, methodical brining, and controlled slow age drying. This process, perfected over years of trial and adaptation, produces limes with flavour depth uncommon in conventional citrus products.
Their commitment to working with nature rather than against it shapes every aspect of production. The family’s focus on quality over quantity has established Australian Black Limes as the country’s first black lime producer. This achievement represents more than business success—it’s a legacy of dedication that touches on sustainable living, ethical farming, and the preservation of artisanal food production techniques.
The Art of Black Lime: From Fresh to Fermented

Black limes, traditionally known as dried limes or loomi, have held revered positions in Middle Eastern and North African cuisine for centuries. At Australian Black Limes, fresh sun-ripened limes undergo a fascinating transformation that balances art with science. The process begins with selecting premium green limes, which receive brief brining to initiate natural fermentation processes.
The limes then undergo slow age-drying under carefully controlled conditions, gradually shifting from vibrant green to deep, alluring black. This transformation requires approximately 5 kilograms of fresh fruit to produce just 1 kilogram of intensely flavoured black limes. The concentration process intensifies not only flavour but also the natural gut-friendly qualities that make these limes particularly appealing to health-conscious consumers.
| Fresh Limes | Black Limes |
|---|---|
| 5kg input | 1kg output |
| Bright, acidic flavour | Complex, smoky, tangy |
| Limited shelf life | Extended preservation for up to 2 years |
| Single-note citrus | Multi-layered taste profile |
| Fresh applications only | Versatile culinary uses |
What makes this transformation so remarkable? The meticulous drying method preserves and enhances the lime’s natural complexity, creating a balance of tang, bitterness, and distinctive smoky accents. Behind this transformation lies a combination of traditional methods passed down through generations and innovative practices developed specifically by the Trethewey family. Each lime carries the story of careful cultivation, respect for tradition, and commitment to sustainability.
Australian Black Limes offers their product in both whole and powdered forms, catering to diverse culinary applications. Whole black limes can be pierced to infuse slow-cooked dishes like stews and tagines, while the ground powder adds surprising depth to modern cocktails and desserts. By avoiding synthetic additives and preservatives, the final product retains the pure, natural essence that continues to capture the imagination of culinary professionals across Australia.
Off-Grid, Sustainable Farming: A Commitment to the Land

Solar panels glisten across the Trethewey family’s property in Wanerie, Western Australia, powering an operation that embodies true environmental stewardship. Their off-grid setup demonstrates that self-sufficient farming can produce exceptional results while minimizing ecological impact. This commitment to renewable energy reflects their core belief in working harmoniously with natural systems rather than exploiting them.
The family adopts regenerative farming practices that are eliminating chemical pesticides entirely. Instead, they focus on responsible fertilizer methods that support healthy trees and robust fruit development. Veronica Trethewey notes that limes possess natural resistance to many common pests, making spray-free cultivation not just possible but preferable for maintaining flavour integrity and environmental health.

Their 500-tree orchard functions as more than just a citrus farm—it’s a thriving ecosystem that provides habitat for various animals, including Henry the pig, cattle, and farm dogs.
This dedication extends far beyond agricultural practices. The family’s hands-on methods, from meticulous harvesting to controlled drying, reflect their commitment to producing authentic food with complete integrity. By relying exclusively on renewable energy and natural processes, Australian Black Limes serves as an inspiring model for environmentally responsible agriculture.
