Heavy cream's fridge life depends heavily on whether the container is still sealed — unopened, it can last 1-2 weeks past the printed date; once opened, that window tightens to about a week, since exposure to air and repeated handling introduces more opportunity for bacterial growth.
The clearest spoilage signs for heavy cream are a sour smell, visible lumps or curdling, and a yellowing tint — any one of these, especially curdling, means it's time to discard rather than try to salvage it, since curdled cream won't return to a usable texture even if strained.
Freezing heavy cream (up to 2 months) is a genuine option, but it comes with a real trade-off worth internalizing before you rely on it: frozen and thawed heavy cream can separate and will not whip into stiff peaks — it's still useful in cooked sauces and baking, just not for anything where you need it to hold its whipped structure.
Heavy cream's high fat content makes it somewhat more resilient in the fridge than lower-fat dairy, but it should still be stored toward the back of a shelf rather than the door, where temperature fluctuates more with each opening.
A sour smell or visible curdling in the carton are the clear spoilage signs — heavy cream that's simply thickened slightly, without an off smell, is often still fine to use in a cooked application.
An unopened carton generally keeps a bit past its printed date; once opened, the shorter window applies regardless of the date on the container.

Frequently asked questions
Does heavy cream last longer unopened than opened?
Yes, meaningfully — unopened, it can last 1-2 weeks past its printed date; once opened, that shrinks to roughly a week, since the sealed container protects it from the air exposure and handling that speed up spoilage.
Can I still whip heavy cream after it's been frozen and thawed?
No — freezing disrupts the fat structure that lets cream trap air and hold a whipped shape, so thawed heavy cream should be reserved for cooking or baking, not whipping into a topping.
What's the difference between curdling and normal thickening in heavy cream?
Curdling is a sign of spoilage — visible lumps or a broken, separated texture that doesn't smooth back out when stirred. Cream naturally thickens slightly as it ages within its normal shelf life, but true curdling is a distinct texture change that should be treated as a discard signal.
Can I tell heavy cream has gone bad just by looking at the date on the carton?
Not reliably — the printed date is a guide, not a guarantee; an unopened carton can occasionally go off before its date if it wasn't kept consistently cold, so checking smell and texture matters more than the date alone.
Does ultra-pasteurized heavy cream last longer than regular pasteurized?
Generally yes — the more intensive heat treatment behind ultra-pasteurization extends unopened shelf life somewhat, though once opened, both types should be treated with the same fridge-life caution outlined above.
