You can drink it warm or chilled. Traditionally, Vikings were said to have warmed their mead by dipping a hot fire poker in their filled cup, but half a minute in the microwave suffices for me. I only ever warm spiced mead though, and never of my own homemade brew.
Traditionally, it was drunk in a lot of different places, so there's plenty of different traditional ways to serve it

. Think of it as honey
wine and you're on the right track... there's more than one variety, so there's more than one ideal temperature etcetera.
I'm curious as to how much home brewed mead you've had? Every time I've had home brewed anything, it's tasted pretty nasty and given me the mother of all hangovers. There's a reason the professionals are professionals.
Then whoever been brewing the homebrew you've drunk svcks at it :shrug:.
Anyone who can follow a recipe and keep things sanitised should be quite capable of producing good stuff. Of course, one also has to have the money to afford the equipment (some stuff can be skipped or improvised, though) and decent ingredients (which can't be skipped or improvised)...
