Does flour go bad?

Yes, flour does go bad, developing a stale, musty, or sour smell, appearing discolored, clumpy, or showing mold/pests, though it's primarily a quality issue, not a major safety risk unless moldy. Refined flours last longer (up to a year), while whole grain and nut flours spoil faster due to oils in the germ, but proper storage in an airtight container in the fridge or freezer extends their life significantly.

Can I use flour that expired 2 years ago?

Yes, you can often use flour two years past its "best by" date, especially white flour, but you must check for spoilage (musty smell, bugs, off-color/taste) and be aware that its quality, leavening power (gluten), and flavor might be diminished, making it better for thickening or coating than for important baked goods. Whole grain flours spoil faster due to natural oils and should be discarded sooner if they smell rancid. 

How do you know if your flour is bad?

Is 7 year old flour still good?

A 7-year-old flour is likely past its prime and not recommended for most baking, especially if it's whole grain or poorly stored, but its safety and usability depend on the type and smell; refined white flour stored airtight might still be okay for non-critical uses if it smells neutral, but whole wheat or flour with a rancid odor should be discarded to avoid off-flavors or potential spoilage. Always check for pests (weevils), mold, and especially a musty or sour smell before even considering it, as rancidity (from fats oxidizing) is the main concern, say Reddit users and Quora contributors.
