This year I've decided to make a 5 gallon carboy of mead. I have watched lots of mead making videos and done a bit of light reading on the subject so I have some basic understanding of the process. The thing is that every video or tutorial I've read says to add something to it besides just the honey, water and brewers yeast, such as oranges, or raisins. But I don't want to add anything to it other than honey, water and yeast. So my question is this: Is it really that important to add other ingredients for the fermintation process or is it really just for flavor?
