About this episode
In the Season 6 premiere of Eat Sleep Wine Repeat, Janina is joined by Sunny Hodge, founder of Diogenes the Dog wine bar in London and author of The Cynic’s Guide to Wine (use code EATSLEEP15 for 15% off this book and all Academie du Vin books). Known for shaking up traditional wine education, Sunny takes us on a journey into the science behind wine, from rootstocks and yeast strains to soils, sulphites and histamines. This episode dives deep into how low-intervention vs. natural wine is defined, what mouse taint and Brettanomyces really mean for your glass, and why the future of wine chat might balance both the romance of terroir and the hard facts of winemaking. Expect myth-busting, geeky insights, and plenty of food for thought on how wine is grown, made, and enjoyed. If you’ve ever wondered what truly changes your wine beyond the grape – from organic regulations in the EU vs. USA, to terpenes, esters, and thiols – this is an episode that will transform the way you understand every sip.
