My personal favorite is Basswood, man it smells good. However, Smells (and tastes) are subjective as already stated, and each colony has subtle differences IMHO. Much depends on what's going on inside and outside. Most people tell me they love the smell of my honey house/garage :-D whether there is any honey in there or not. Fresh comb can smell pretty good to. I like spending time with my bees whenever a flow is on, listening (and smelling) to those "snap, crackle and pop" sounds as they make new wax to fill with honey. Yummmmm.
Unfortunately for Basswood, conditions must be near perfect to produce nectar. This year, despite a massive blooming of a big Basswood behind our house, due to drought conditions and thus a lack of nectar, it drew no interest from honeybees. We did not see a single bee visit any of our Basswoods regardless of how much it bloomed or how wonderful it smelled.........to us.
Basswood blooms for just 2-3 weeks and when the stars are lined up in harmony we (and our bees) celebrate BIG TIME with gobs of Basswood Honey! Unfortunately, since 2007 we and our bees have only produced our own Basswood honey twice. Some years they don't even flower :( Like several other favorite Honeys, CONDITIONS are everything.
As for goldenrod honey, it ain't bad at all once capped, but we usually leave all of it for the bees. In fact we stop taking honey in August. They will need (and we try to leave them or feed them) 100 pounds of honey to survive our winters. Like many folks, Goldenrod is the last flow around here (and even that doesn't always make nectar).
Asters are also very attractive to bees this time of year but I'm uncertain whether they are getting nectar or pollen or both. I've only 'heard' that it makes a nice light honey and not sure of its smell :?
