I just started my first mead last week too! 15# honey in 5 gal, but I used liquid Mead yeast, and some nutrient and energizer. Took 2 days to get bubbling, but SG has dropped now from 1.100 to 1.085! My instructions say to add some more nutrient when SG drops by 1/3 to keep feeding those yeasts.
I have made wine before, but not Mead. Pretty excited. Plus I like stirring it daily.
