How long can you keep vacuum sealed fat frozen in a freezer?

I always keep brisket fat trimmings and use them when I grind my own hamburger. I haven't done that for a while, but with beef prices still hight, I think I start doing it again. The fat I have is pre pandemic.

I generally keep vac sealed meats/poultry no longer than 3 years. I don't think that they magically go bad after 3 years have passed, but quality does drop off after so long. With fat trim, I dunno, but I'd probably treat it the same.

What Doug said.... Usually I keep all meat trimmings and fat for not longer then 3.5 years and Ii use them to make sausages..
Recently I found a bug of 4 plus years old fat (all vac sealed) and decided to dump it....

Beef fat will go bad a lot sooner than pork fat, but in general it all depends on how the animal was fed. I've had beef fat keep frozen for a year, and I've had some go bad in less than 3 months. 3 years is pushing it IMO....for beef fat. Pork fat might still be good after that much time being frozen if it was sealed well.
