Loads, it's one of my favourite tipples. I've never seen it colourless though.
Proper mead tastes like mild, alcoholic, slightly spiced honey; but there's a massive range, it's a bit like trying to describe what wine or cider tastes like to someone who's never had it.
Some meads though basically cheat, and just dissolve honey in a stronger alcohol drink, brandy, sherry, absinthe etc.
Typically alcohol EBV is broadly equivalent to wine. 10-15%, and you'd sip it like an appéretif, generally better chilled.
