The smell is a bit creamy, malty, strong, bitter, and possibly dark, but this could all be placebo. The initial taste is pretty mellow, but it seems to get more and more mellow, while also allowing the ABV to stand tall. Marshmallow is a very obvious ending to me, after a creamy milky cereal bowl taste combined with a tad of citrus starts the round off. This is an interesting experience to me; although it's been a while since I've had standard Jameson, I know this does not have a similar taste to the classic.
