Are your friends French? If so, you might want to re-think your plan. One evening my parents and I arrived at their Parisian friends' apartment where we were going to dine and stay a couple of nights. I had read that French hosts are insulted if you bring a bottle of wine with you when invited to dine at their homes, but that barely prepared me for our host's stunned look when my father handed him one. He recovered quickly and thanked my father — but the bottle of crémant went onto a shelf.
French people consider wine selection to be a key part of preparing a dinner. They're not likely to serve a wine that just happens to arrive at their door with one of their guests.
