These Blenheim Apricots are not treated with sulfur dioxide (a preservative) which gives it the unique color it has, these fruits are also sun dried but have a slightly different taste to the traditional Blenheim Apricots with Sulfur. Still a great gift to give out or put in your trail mixes. We recommend these be eaten as soon as possible or stored in the refrigerator as these Apricots are more likely to spoil quicker than the others because they have no preservatives.
