Well, the dinner was a big hit and we enjoyed two new wines. With all the recommendations I received, I went into a favorite shop of mine, Fine Wine Brokers, with a set game plan. However, as usual, I couldn't resist asking the opinion of the staff. I planned on trying the Sancerre with the 1st two courses, but was persuaded to try a Pouilly-Franc as an alternative. I thought it was a great choice, a little richer than the usual Sauvignon Blanc that I love, and it went really well with the smoked trout (my favorite course- for flavor and presentation - the beets were a great color).
I liked the idea of pairing the traditional cassolet (my first) wine, so I went with the Madiran. Although I wasn't wowed by the cassoulet itself -besides the excellent veal sausage, I found it a bit flat - the madiran really lifted that course up with a strong earthy flavor.
Great idea wino on keeping a glass of white around for the salad!
The mousse was also a highlight. The chef who made it told us the restaurant she studied at in France wouldn't let her do anything but make mousse because of her inexperience. So needless to say she got really good at it. We tried a port at the recommendation of the staff at Fine Wine Brokers that I can't remember the name of at the moment.
Thanks for the advice! Now I still have some great ideas to try.
