Some that were immediately clear were malt and carmel. Two others that surprised me with their presence later were salt and nuttiness. I should take a moment to say that I find salt and nuts to greatly enhance the flavor of milk chocolates, and in some rare cases, dark chocolates. Valrhona makes a divine dark chocolate with hazelnuts that I'll review if I ever branch out into reviewing chocolates with nuts. Both salt and nuts are complementary flavors that add a lot of richness to the chocolate without taking away from the chocolate flavor itself.
Many milk chocolates add more milk, cream, or cocoa butter to add richness by adding fat.
Of course, adding fat means taking away cocoa. So an underlying saltiness and hint of of nuts are a good thing. Anyway, if you can find this chocolate anywhere, I'd suggest giving it a try. It's certainly interesting and different. I know it's available in parts of California, since my mom sent me the sample I used from there.
