Is it possible to save an opened bag of grass seed for next spring? If so,
how would you store it over the winter?

As long as you keep the seed dry and where the mice cannot get at it, it
should be fine. I grew snap peas this year from seeds I bought years ago.
Seeds were found in the pyramids of Egypt that could still germinate.

The suggestion of another reply to keep them moist or in water was silly.
As long as they remain dry, they should be able to sprout when they are
planted and remain moist.
