suitable wines to go with wedding menu, to purchase in France

[chris morgans]

My fiance and I get married on 5th May. Our guests at the reception will be offered a starter of fresh salmon and the main course will be roast spring lamb with all the trimmings.
We are going to visit France for a few days in a couple of weeks (the exchange rate is excellent etc.) to visit Epernay to buy the Champagne but would also like to buy both Red and White wines (at least one type of each) in bulk to go with the food.
Our preference would be to visit the region as we will with the Champagne but this is probably not practical as we are only there for 3 days. Hence we will be buying from some retail source.
Any thoughts / comments would be welcomed.
