Martín Kaiser excels as both a viticulturist and a winemaker. Born and brought up in Mendoza, where he still works and lives, he has transformed the reds and whites of Doña Paula since he arrived in 2006, taking them back to their roots. Our fascinating chat covered everything from vegetarianism to climbing mountains, calcium carbonate to the joys of working with Malbec and the differences between the Uco Valley and Luján de Cuyo. To read more about Martín have a look at the Doña Paula website. You can also follow him on Instagram at @mkaiser75.  Don’t forget, Cork Talk is now available on Spotify as well as Apple Podcasts. You can listen to this week’s episode, plus my back catalogue of interviews with some of the world’s most extraordinary wine figures.
