I have not made my first batch of mead yet, but I am very excited about making a batch. I have order a hydrometer, but I just cannot wrap my head around the calculations involved in ABV and SG.

I want to make 5 liters of mead to start with as a practice, so I don't waste too much if it goes wrong. I would like it to be 12% and be medium rather than sweet. I will add fresh orange slices to see what that tastes like. Does anyone have any idea how I make that calculation as to how much honey to make?

I know there is a section in the NewBees guide on the calculator and the statistics, but no matter how often I read it, I just can't understand.
