I have yet to taste a good commercial mead. Or a good homebrewed one for that matter! Well, no I take that back. A friend of mine makes a really tasty (in my limited experience) blueberry melomel.
I have tried a few different meads from a place up here in Vermont called Honey Gardens. I have found them to be much like my failed attempts at meads. They are far from what I would call "nectar of the gods" There always seems to be a bitterness and wintergreen (wax lips I call it) flavor to their meads and my own. I had some from a meadery in Maine also. More drinkable, but again, nothing to swoon over.
Maybe I just don't like mead.
If you like wine and you like honey you should enjoy a Mead if it is made properly as a well made Mead should be smooth, easily drinkable, not too much alcohol, no wax flavors and definitely not bitter or tannic - it should be a balance of smooth alcohol, pleasant honey aromas and flavors, just the right amount of acid to balance the sweetness of the honey and if any fruit/spice is added then that should also harmonize with the honey, alcohol and acid of the base Mead.
Don't give up on finding a great Mead as they are out there.
