Mead-wise, there are many variations, branded and otherwise... from a light, pale wine with barely any flavour, to a thick syrup that is basically honey in a bottle, with added sugar and black treacle. Like with whisky, you have to try them all and pick your faves.
My personal regulars include Moniak (Scottish brew, very thick and overly sweet), Drunken Monk, Lindisfarne, Lyme Bay and Lurgashall. Most do standard mead, and variants such as spiced, mulled and Christmas!
I have some places where I'll find locally produced meads, including one with heather. They also do a heather ale, similar to Fraoch but with a stronger flavour.
