Does balsam smell like pine?
Balsam fir has a more syrupy/sweet-ish scent than silver fir. Spruce tends to be a “darker” scent, as does cedar. If you like wine, a good way of describing the difference between spruce and pine is that spruce is a bit more tannic in a fruity-dry way.
If you were to crush balsam needles in your hand this is exactly what it smells like. I like it a lot. It is a clean, fairly astringent smell.
