We all know about potassium sorbate. What are some other chemicals in frozen concentrates, syrups, etc. that inhibit yeast growth? Feel free to post your experience and I'll keep a running list in this first post for people to use as a reference:

BAD for yeast growth:

1. Potassium Sorbate
2. Sodium Benzoate
3.

OK for yeast growth:

1. Citric Acid
2. Potassium Metabisulfite (K-meta, Campden, when not used in conjunction with Potassium Sorbate)
3. Ascorbic Acid (Vitamin C)
4.

UNKNOWN effect on yeast growth:

1. Sodium Nitrate
2. Sodium Nitrite
3. Sodium Bisulfite
4. Sulfur Dioxide
5. Potassium Hydrogen Sulfite
6. Calcium Propionate
7. Magnesium Stearate
8.

Sodium Benzoate should go under Potassium Sorbate.
What is Sodium Benzoate?

Need to add ascorbic acid (aka Vitamin C) to your list of OK chemicals.
