This is a work in progress for me. I started to look for a good map of Pomerol and few had exact holdings of each producer. I used the public French cadastre (plot) website and several sources* to identify which vineyards belong to who. I would say this is an unofficial map, however some are exact to the representations on the producer websites, i.e. Château Nenin.
Pomerol is relatively small and has big hitters along the same addresses. It’s important to note the plateau in the east where the the most famous producers are located. Petrus, Lafleur, Hosanna, Vieux Château Certan, Le Pin almost all share a border.
The western part is still important, I didn’t mean to leave it unmapped, but as you can see, there are many tiny plots and it’s requiring more investigation.
