I put it in zip lock freezer bags and squeeze all the air out of them before sealing. I then roll that up tight in freezer foil so there are about 3 layers. Then I tape it and date it. If I don't date it I could never tell from looks how old it was. A year is not normally a problem if you can keep it that long. This year I gave too much away and I'm thinking I'm going to run out. Nahhh, crop damage starts July 1.
