It cannot be said that Argentine billionaire Alejandro Bulgheroni, owner of the eponymous winery Napa Valley, does not put his money where is mouth is. In the pursuit of extreme winemaking to produce world-class, cool climate Chardonnay and Pinot Noir, he founded Otronia at 45.33 degrees South in the province of Chubut in Patagonia’s far south. This is the world's most southerly winemaking region and Otronia's vineyards are Argentina's most Southern.

Planted on the south-east shore of Lake Musters, the environment is incredibly hostile. As well as the bitterly cold temperatures and risk of year round frost, there is surprisingly little rainfall and extreme winds regularly reach up to 110km/hr. The estate use nets as well as planting thousands of trees around the vineyard to help protect the vines from the lashing gales. Braving these merciless conditions conditions has proved worthwhile as they give rise to elegant wines with distinct vibrancy, aromatic intensity and a very unique sense of place.

It is not just the location that is special, Otronia also has an amazing team. Head Winemaker is rising star Juan Pablo Murgia who was named 'Young winemaker of the Year' by Tim Atkin MW in his 2021 Argentina Special Report, but significantly he is supported by world-renowned consultant Alberto Antonini, the famed former director of winemaking for Antinori. Antonini's influence can be seen in the hands off approach, using concrete eggs and large, neutral French oak to enhance the wine’s character, not mask it.
