Hi Kevin, welcome aboard.
I don't make mead, I have made spiced beers. I find that a teaspoon of cinnamon blend in five gallons adds light spice to the finished brew. My theory is always go light, too little might disappoint, but too much can ruin your brew. I also read successful recipes for suggestions. Check HBT for mead recipes with plenty of positive feedback. Good luck with it, let us know what you do.
