If it has preservative in it, you shouldn't have to freeze it.
I make large batches and freeze it in four ounce portions--even though I do add preservative. I just feel better doing that. While it's my current favorite product, I only use it once in 5 days, if that. I "save" it for special occasions, so it's not always the fifth day.
