Saving breakfast sausage grease?

I just canned up around 9 pounds of ground breakfast  sausage and there's a lot of grease.

I filtered it and came up with 32 ounces of grease!

I put it in the fridge for now.

My question  is, how long will it last?
Is it the same as saving bacon grease?

I was going to use it in cornbread recipes and butter replacement for cooking.

We keep lard in the fridge for up to a year wth no degradation.  It does go rancid after several weeks if left on the counter.  Your grease may have some sage, pepper, or other spice flavor, but I don't see how it would be any different.
