The taste is kind of hard to describe. It's confusing. Definitely a little sweet because it has heaps of sugar and syrup in it but the aftertaste is pretty sour, almost beer-like (because it has malt in it). I think rye bread is pretty rare outside of Finland too but if you've ever tasted it, Mämmi is a bit like sweet rye bread seasoned with malt in a porridge form. Well, that sounds weird, but it's kind of an acquired taste really. But it's not as bad as it looks.
