Champagne has over 8,000 vineyard parcels, each shaped by millions of years of geology, unique microclimates, and centuries of winemaking tradition. Yet there was no single place to explore this data. It was scattered across government archives, academic papers, and local knowledge passed down through generations. I built Parcelles to bring it all together — so that anyone with a curiosity for Champagne can understand what makes each vineyard unique, from the chalk beneath the soil to the bottle in your hand.
