Essi Avellan is a journalist and Master of Wine who probably knows more about sparkling wines than anyone else on the planet. I caught up with her from her base in Helsinki to talk about single vineyard Champagnes, autolysis, cork age, tasting bubbles, the best fizz regions outside France, her preference for fresher over oxidative styles, the impact of climate change and the future of grape growing in Finland.

To read more about Essi have a look at her website. You can also follow her on Instagram @essiavellan.

Don’t forget, Cork Talk is now available on Spotify. You can listen to this week’s episode, plus my back catalogue of interviews with some of the world’s most extraordinary wine figures.
