I recently learned about ClimeVinea, a new iPhone map app, with lots of info included. From their web site:
ClimaVinea provides a fully interactive version of Sylvain Pitiot’s state-of-the-art vineyard maps that appeared in the book “The Climats and Lieux-dits of the Great Vineyards of Burgundy”
It’s $25 to purchase, but seems worth that to have a detailed interactive map of all of Burgundy, with lots of info on vineyards and producers. No affiliation, just thought it was cool and didn’t find it with a search here.
