I've made it. It's actually pretty tough to do well as there is nothing to hide mistakes. With beer you've got all sorts of specialty grains and hops and the flavor of most is strong enough to cover bad flavors in another ingredient. Good mead is nothing but water, honey and yeast. ANY mistakes in the cooking process, any mistakes in the fermenting process, poor water quality, the wrong yeast variety, bad honey, etc etc etc will all ruin a batch of mead. Done right by a competent brewer mead is delicious. It's light and fairly dry, NOT heavy and sweet.
