Vineyard Manager

Jonathan Shearer (commonly known as ‘Jono’) has been with the Rosemount Estate viticulture team since 2012.  After growing up not far from the McLaren Vale wine region, Jono spent 12 years working in a range of wine regions in Australia and the USA before coming back to his roots in 2012.

Jono was raised on the land and decided at a young age that working outdoors was important. Every season is different, and for Jono, it’s the drive to grow the perfect grapes for winemakers to craft the perfect wine that makes this industry so much fun to work in. 

Fresh out of school, Jono commenced a Bachelor of Agriculture (Viticulture) at the University of Adelaide.  Amongst studying, playing indoor cricket and a healthy dose of partying, Jono worked with Hardy’s and Richard Hamilton Wines in his university breaks, learning vineyard operator tasks such as pruning, netting, harvesting and tractor operations.

In 1999, Jono combined his final semester with a full-time Technical Officer position with Australian Vintage in the warm climate of the Riverland, based in Loxton. He graduated from university and continued at Australian Vintage for two and a half years.

Jono then changed to cooler climate viticulture joining Southcorp Wines in Padthaway. He was soon promoted to Vineyard Manager of a 115Ha vineyard in Tumbarumba, NSW, where snow in November made vineyard management challenging, but provided excellent cool climate Chardonnay and Pinot Noir sparkling fruit for Seppelt and Yellowglen. Jono was subsequently rewarded with a stint in the warm climate of Heathcote, tending to large vineyards of premium Shiraz bound for Penfolds and Seppelt. 

After nine years, four Australian wine regions, three states (and child born in each state completing his family), he set off with the family to USA. After a crash course in Imperial measurement and Spanish, Jono found growing wine grapes in California a fantastic experience.

It was in 2012 that Jono returned home to join the Rosemount Estate viticulture team as Vineyard Manager of 440 hectares of vineyard in McLaren Vale.

His favourite wines are Rosemount Estate Balmoral Shiraz, GSM and the Single Vineyard Series ‘Q Block’ Cabernet Sauvignon.
