That's a pretty broad question. What do you like in beer? Fruit? Spice? Plain? You can make almost anything... Use apple juice (cyser) in it, if you like a cider, or spices. My first mead I used ginger, cinnamon, and clove (metheglin). Came out fantastic. I currently have two fruit meads (melomels) going: an apricot and a peach mead. The possibilities, like beer are endless. And in my opinion, meads are easier than beer to make. (They just take longer) Do you like sweet? Dry? Carbonated or still?
I would suggest trying a true, plain mead, get a feel for the flavors. Then play with it. Or like me, I tried several different store bought and home brewed meads before making my first.
