Field Trip to Avondale Wines in Paarl, South Africa. Today we’re in conversation with Johnathan Grieve, winemaker and proprietor of Avondale Wine Estate, who talks about the importance of healthy soil, and why their wine is elegant, beautiful, complex wine with a true sense of place. Biodynamic farming supports a healthier soil and a better planet. Because as Jonathan says: “Terra est vita.” If you’re in South Africa, do yourself a favor and visit Avondale.
