Rebecca Gibb is a Master of Wine. A ninja who can sniff out a Merlot from a Margot at 50 paces. I know ABSOLUTELY nothing about wine other than I like drinking it. So we had a lot to talk about. She has written a fascinating research paper on the riots that tore through the region of Champagne just before the First World War as the small wine growers rose up against the power of the big Champagne brands. This story has it all: invasive species, globalisation, climate crisis, superbrands, booze and artisanal production.
