English has virtually no words that denote scent exclusively, especially pleasant scents. There, everything is metaphor.
In the parlance of certain technical groups, spices may indeed have a very specific reference -- even going so far in some cases as naming the chemical congeners -- but wine tech talk, cheese tech talk, chef tech talk, perfume tech talk, and many many other ingroup technical dialects where a Spice metaphor is used descriptively will vary enormously on the details of what is meant by it.
In other words, talk to a perfumer and get examples. That's the only way you'll ever find out. We can only offer speculation here, unless someone here is a perfumer (which is possible). If so, defer to their opinion.
This is all assuming, of course, that whoever wrote the sentence knew what they were talking about, and how to talk about it meaningfully. This may well not be true, expecially in advertising copy.
