About us

GrapeFever is your path to learning about wine. We make tasting wine easy and pleasant, focusing on the “hedonistic tasting” but learning the basic techniques and features of the wine. We want you to experience the true culture of our city by not only walking around our neighborhoods but getting to know places you wouldn’t typically find on your own. GrapeFever is a connection with all your senses, sight, smell, taste, touch, and hearing. Our culinary tours are designed to take you through Argentina’s best wines, focusing on Boutique Wineries, the food beyond a “parrilla” and taste our city in a whole different way.

Davin Rockstad

Sommelier. He was born in chilly Alaska, and first exposed to wine when his family relocated in the heart of wine country in Sonoma County, California. However, it wasn’t until he moved to Argentina in 2005 that his full-blown wine love affair began. After receiving a Masters in Communication from the Universidad de San Andres, he studied at the Escuela Argentina de Vinos, traveled through the different wine regions in Argentina and worked as a Sommelier at a Boutique Wine Hotel. He dares people to go beyond the Malbec and try a racy Torrontes from the highest vineyards in the world, a sublime Patagonian Pinot Noir or bursting Bonarda from the arid mountains of San Juan. Fluent in both English and Spanish, he finds that an appetite for wine, and learning about it, is truly a global language.


Rolando Llerena Guevara

Bartender and Sommelier. He helps us define all the do’s and dont’s when setting up your bar and of course, leads a few wine tastings himself! Rolando is from Ecuador where he began his extensive career as a bartender, and has been living in Argentina for 3 years.
