"What do meads taste like?"
Simple question, difficult answer, and not really related to this thread.
Mead is wine made from honey, so it tastes like honey wine.
The thing is, mead is an open canvas of flavor. Ken Schramm's Compleat Mead Maker is a terrific read. You should also visit gotmead.com and peruse the newbie guide.
Spices, fruits, varietal honeys, yeasts, age, oak, temperature... so many things affect flavor...it's like describing what chicken tastes like.
It's wine. To me, it's delicious. It's also a rewarding hobby.
I really hope more and more people get into making it. I want to see mead become mainstream and respected like grape wine. If you have a meadery nearby, support them!
