Hey Ted,
I'm going to take a shot at it, have to wait until I have a free carboy, that and the Thai iced mead.
I had only made one mead before starting the peanut butter mead, only way to get experience is to jump in feet first (and read everything you can find on the subject).
The Avocado / Breakfast Tea mead, is bitter, not sure if its the tea or the honey?
I'll make a gallon of straight Avocado mead and see what that taste like.
The Buckwheat / Black Current mead, is starting to taste more like red wine then mead.
The Sage / Peanut Butter mead is wonderful, though it taste better warm then chilled.
They all have a ways to go before finishing so time will tell what the out come is.
I have found, by placing the sample used for S.G. in the fridge over night, it settles and can be tasted without the solids, this gives a better idea of where the mead is at.
