Hi Steve -
I always buy the same brand (SAF Red Instant), and it's good for at
least a year past the expiration date on the package. That's based
on a combination of things I've read at the KA Flour website, and
experience. If I've had it more than a year after the date and don't
get a good rise in my bread, I would toss the rest of it and start
over. It hasn't happened yet. If I found some that was two years
after the expiration date, I would toss it.
Like many others, I keep it in a tightly sealed container in my freezer.

Steve asks: I have been going go through the archived messages on
yeast. So we buy our yeast in bulk and freeze it. How do we know when
yeast goes bad?
