Kent - If you mean true Simple Syrup (speaking pharmaceutically) which is
850 grams sugar in enough water to make 1000 ml, you don't need any
preservative. The osmotic pressure is so high in this solution that
organisms can't grow. I make up syrup less concentrated than real Simple
Syrup and still notice no growth for months. Store in the frig. for added
protection.
