I am so confused. I tried searching on chemicals and got a bunch of posts on "natural" mead making. But none answered my question of today. If there is a post that will answer these things, please feel free to point me to it. I can read the forum happily for hours at a time, but I'd *really* like to make some mead this weekend instead of read!
1. Sulfates, sulphur dioxide, campden, metabisulfite. I read that you should not use dried fruit in your mead that has been treated with sulphur dioxide, for fear it will impair or kill the fermentation. Yet, campden tablets and metabisulfite are designed to produce sulphur dioxide to sterilize the must and kill any undesired yeasts. And... these ingredients are sometimes used before pitching the yeast???
2. Sorbates - used to stop the yeasts from reproducing and continuing to ferment. Isn't this kinda the same thing that metabisulfite does? Why do you need both?
3. Nutrient additions - this is where I'm really confused. DAP apparently is toxic to new yeast colonies. But it's supposed to feed yeast. So how do you use it?
Which nutrients are best? And when do you use each? There are a lot of variations between the different nutrients. I don't know the pros and cons between adding some of these things.
Fermaid K: ammonia salts, alpha amino nitrogen, sterols, unsaturated fatty acids, other key nutrients, and inactive yeast.
Fermax: Di-ammonium phosphate and yeast hulls.
Go-Ferm: a yeast nutrient used during the rehydration of dried yeast.
Yeast Energizer: DAP, yeast hulls, vitamins, and magnesium sulphate
Yeast Hulls
On a side note, I think I scored something cool today. Picked up a pound of dried mango with zero added ingredients in it. No sugar, no sulphur dioxide, etc. Now... what to do with it... Hmmm... Ideas are solicited.
