I read someplace that seeds stored with no oxygen would not sprout. I unsealed the the mylar bag to get the berries out to sprout them in mason jars with cheese cloth on top of the jars. the seeds (berries) have been sealed in a pail since late 2005,it's hard to tell by the pic, but the mylay bag is sucked tight,2000cc oxt absorbers in the pail. the second picture is the sprouted berries after 4 days. everyone should do a little experment to see if theirs will sprout, they taste sweet.
