Freezing almond seeds?

I tasted one of my almonds this morning and it was stale. These nuts are probably 5-6 years old but they were gathered for seed. I have put some in the ground to sprout over winter, some in the refrigerator to cold stratify for planting inside, and have probably a couple dozen left that I would like to store in the freezer.

Will freezing them work? I tried freezing chestnuts and they all died.

The almond seeds have sprouted just fine in the past, it's my neglect that kills them.
