About this app

Champagne, decoded.

Parcelles is a detailed, data-driven explorer of Champagne's 8,000+ vineyard parcels. From the chalk beneath the vines to the bottle in your hand, every parcel has a story — and Parcelles brings it all together in one beautiful app.

EXPLORE THE REGION
Browse the entire Champagne wine region on a detailed interactive map. Tap any parcel to see its name, village, and classification instantly. Search across every vineyard, village, producer, and bottling.

KNOW YOUR TERROIR
Every parcel analyzed with altitude, slope, aspect, sun exposure, soil composition, and rankings against all of Champagne. Understand what makes each vineyard unique.

WHAT LIES BENEATH
Geology overlays, contour lines, and hillshade reveal the terrain that shapes each vineyard. Elevation profiles with surface geology and projected underground rock layers — reconstructed from real boreholes.

DECADES OF CLIMATE
Growing degree days, rainfall, frost, and sunshine decade by decade since 1950. See how climate has shaped the vines — best years, worst years, all-time records, village by village. Plus a forward-looking Climate Outlook with CMIP6 projections through 2040.

SEASON TRACKER
Follow the growing season day by day. Growing degree days, 3-day weather forecast, frost warnings, vintage archetype forecasts, and harvest predictions — village by village, updated daily.

What’s new

Inside the blend. Tap Blend on any cuvée and it opens grape by grape, with the base vintage and the reserve wine share behind it where the house publishes them. Numbered editions now sit together as one series, each with its own blend. Add a bottle to your journal in one tap and watch your rank move. The Spécial Club growers get their own section, and rosés say how they took their colour where we know it. New for members: the whole Champagne map, offline.
