Cru de Beaujolais

Hi Dad, Last month while in Chicago you poured us a very flavorful Morgon that I quite enjoyed.You mentioned it was a "cru du Beaujolais".I'm familair with regular Beaujolais especially Beaujolais nouveau, but not with Cru du Beaujolais. On our vacation in Cape Cod last week I found a couple bottles of Cru du Beaujolais and it went over well with our friends. What does this appelation cover? What are you favorites? Which one can you find in an American wine store?What food pairing you recommend? We had it with a nice light pasta and it seemed to pair well. Thanks for the intoduction to this delightful appelation! Stephane
