@ZipLine-- If Saint-Andre ages, it can turn yellow and take on a slightly stronger flavor. Saint-Andre is usually eaten young though because it goes bad quickly. It sounds like you ate a Saint-Andre cheese that was close to going bad. And I hope that you didn't eat the rind, because it's not meant to be eaten.
I love Saint-Andre, but only the French ones. Unfortunately, the last time I went to France, I couldn't have any because I was pregnant. Almost all Saint-Andre cheeses in France are made from unpasteurized milk which is dangerous during pregnancy. Actually, more than half of French cheeses are actually made from raw milk, so I basically couldn't have cheese when I was there.
