I'm a big tea drinker at work, and our local public market has a wonderful honey vendor. So, my desk has quite the array of teas and jars of honey! The different honeys DO taste different! Some have very subtle differences, but some are pretty wild. Buckwheat honey is very dark, almost like molasses, and has a very rich flavor, almost a bit smoky. Spring honey is a lighter taste than summer honey. I also have 'berry blossom' honey, which does taste a bit umm... fruitier, I guess?

My cubicle buddy used to work at an apiary, and can tell me what sort of blossom the honey is likely to have come from. It's like having a somellier of honey sitting next to me

The buckwheat honey tastes excellent on oatmeal with a handful of roasted nuts and some dried cranberries.
