About Onannon

Onannon founder, co-owner and winemaker Will Byron is redefining what Mornington Peninsula wine can be. Over two decades of winemaking on the peninsula, he has gained a more precise understanding of the region’s subregions and sites than almost anyone else. His grasp of geographical nuance is supercharged by an intuitive sense of the salient aromatic, flavour and structural characteristics of each batch of fruit, and the courage to act on those instincts. His composed, balanced wines are always long on texture, excitement and personality. They milk the Peninsula’s cool, maritime conditions for slow-ripened flavour and coastal energy, while always dishing up a deliciously intriguing sense of self.

With Will concentrating solely on Onannon from 2021, spectacularly particular single-site bottlings are emblematic of the extra detail across the range. Onannon 2.0 formally launched in 2026, with the amicable withdrawal of Will’s initial founding partners. The arrival of co-owner Pete Finnegan into the fold, plus a custom-built winery on Pete’s supreme Robinson Vineyard in Tuerong, promises a glorious new flourishing for this modern Peninsula flag-bearer.

About Will Byron

Will Byron is the founder, winemaker and co-owner of Onannon. He cut his teeth at Coldstream Hills from 2003 to 2008, working with benchmark Chardonnay and Pinot Noir while absorbing more than a little wisdom—and a few memorable bottles—from founder James Halliday’s cellar. It was here that he met Kaspar Hermann and Sam Middleton, with the three friends establishing Onannon in 2008. Along the way, Will broadened his Pinot horizons through vintages in Burgundy, Central Otago and the Hunter Valley before finding his way to the Mornington Peninsula and Stonier.

During his time at Stonier, Will worked with an extraordinary breadth of Mornington Peninsula Chardonnay and Pinot Noir, developing an intimate understanding of the region’s sites, subregions and nuances while steadily sharpening the Onannon wines alongside it. In 2021, he left Stonier to make Onannon his sole focus, and the label has been on an exhilarating trajectory ever since. Now, with an expanding single-vineyard program and Pete Finnegan of Tuerong’s Robinson Vineyard joining Will as co-owner in 2026, Onannon 2.0 has a new partnership, a permanent home and a very exciting future ahead.
