Less worry, as there’s still no specific study that says saturated fat intake has a consistent link to heart disease.

Bacon grease shelf life depends on how it is made and stored. There are bought in the store and homemade bacon grease that normally last up to 6-months.

On the other hand, homemade bacon grease’ useful life is more difficult to detect. We tend to continually add bacon grease on the same jar resulting in rough shelf life estimates.

It nearly depends upon where it is stored. Putting homemade bacon grease at room temperature will make it last for 6-months. Try placing it inside your fridge and expect it to last a year.
