First stop in the land of really expensive red wine was St. Emillion, which is on the north side of the river and inland a little bit. The entire area is on one huge chalk plateau. So the one vineyard we went to had a huge carved out wine cave under their vines - I'm thinking the floor area would have been at two football fields.
We picked up three bottles from different years of the same winery in order to taste the different harvests in detail.
We also walked around the town of St. Emillion and picked up some Merlot vines - have no idea if they will survive. Alas, the one day it baked in car's back window and the trip home in an overpacked suitcase did not make them very happy - but we'll see.
