However, on her recent visit to Dunedin, she modestly went quiet when introducing the 2010 Signature.
This cabernet shiraz is the best the South Australian family-owned winery makes and each year is dedicated to a person who has made significant contributions to the company.
She is the signatory for the 2010 which has just been released, a great honour, she says.
One of the least fluffy PR people you could meet, she comes across as a straight-talking, down-home person, with a knack for telling a yarn and a huge knowledge of Yalumba, its history, operations, people, wines, and almost everything to do with wine and food.
She travels the world hosting tastings, lunches and dinners from the far south to London and New York.
At Esplanade, she showed several wines made from varieties unfamiliar to many New Zealand wine drinkers.
Originating in the Rhone Valley in southern France, rousanne, viognier, grenache, mataro and shiraz do well in the Barossa where Yalumba is based, not to mention the characteristic Australian blend of cabernet sauvignon and shiraz.
Among the whites were an aromatic but savoury Eden Valley rousanne 2012 ($26), a minerally Y series vermentino 2011 ($18), a rich but hot Eden Valley viognier 2012 ($29), and the elegant, refined and slightly nutty Virgilius 2010, the company's top viognier.
Yalumba introduced this variety, which was declining in its home in Condrieu in the Rhone Valley, to Australia almost 25 years ago.
Among the reds, I enjoyed the floral silky, red-fruited Strapper grenache shiraz mataro 2012 ($25), and the Cigar 2011 ($30) a Coonawarra cabernet sauvignon oozing delicious fruit, intense and aromatic.
The Menzies 2010 ($50) from the same vineyard is impressive, more classically elegant, spicy and complex.
While some Australian reds finish with big, grippy tannins, Yalumba's are more supple while still firm, making them more drinkable, a deliberate winemaking technique since the winery returned to single family ownership in 1989, Ferrari said.
