A good pomegranate feels heavy for its size, has a slightly angular shape with visible ridges, and makes a metallic sound when you tap it. These three checks together are the most reliable way to judge quality, whether you’re standing in the grocery store or pulling one from the back of your fridge. Here’s how to evaluate a pomegranate from the outside in.
Check the Shape First
An unripe pomegranate is perfectly round, like an Asian pear. As the fruit ripens, the arils inside swell with juice and press outward against the skin. Because a pomegranate has four internal compartments, this pressure flattens the fruit slightly on four sides, creating visible ridges and an angular, almost squared-off look. If the pomegranate still looks like a smooth, round ball, it was likely picked too early.
This shape test is one of the most consistent indicators of ripeness. The more pronounced the ridges, the fuller the arils inside.
Weight, Skin, and the Tap Test
Pick the pomegranate up. A ripe one should feel surprisingly heavy for its size, which means the arils are plump and full of juice. If two pomegranates are the same size but one is noticeably heavier, go with the heavier fruit every time.
Next, look at the skin. It should be firm but slightly leathery, not shiny and taut. You can do a quick scratch test: press your fingernail gently against the surface. If the skin gives slightly and you can leave a light mark, the fruit is ripe. An unripe pomegranate has skin so tight and hard that your nail won’t make a dent.
Finally, give it a tap with your fingertips. A ripe pomegranate produces a metallic, somewhat hollow sound. A dull or dense thud usually means the fruit isn’t ready or has started drying out inside.
Why Skin Color Can Be Misleading
Many people assume a deep red pomegranate is a good pomegranate, but color depends heavily on the variety. The “Wonderful” variety sold in most U.S. grocery stores does ripen to a deep ruby red, but other cultivars tell a different story. “Mollar” varieties stay mostly yellow even when fully ripe. “Valenciana” pomegranates have yellowish patches on the skin and pale, white-pink arils inside, yet they’re perfectly fine to eat.
Consumer studies confirm that shoppers strongly prefer red-skinned pomegranates, but that preference is cosmetic, not nutritional. A yellow-skinned pomegranate from a yellow-skinned variety isn’t underripe. The more reliable indicators are always shape, weight, and texture rather than color alone. That said, if you’re buying Wonderful pomegranates (the most common variety at mainstream stores), a rich, even red color with no green patches does signal good ripeness.
What Good Arils Look Like Inside
Once you cut a pomegranate open, the arils should be plump, glossy, and deeply colored for their variety. In red varieties, look for jewel-like seeds ranging from bright ruby to deep garnet. The white membranes separating the sections should be pale, almost cream-colored, and slightly dry.
Squeeze an aril between your fingers. It should burst easily with juice. The woody seed inside varies by cultivar: sweet varieties have noticeably softer seeds, while sour types can be quite hard and crunchy. If you prefer eating pomegranate fresh (rather than juicing it), softer-seeded sweet varieties are more pleasant to chew.
Brown arils or brown membranes are a warning sign. This discoloration typically comes from chilling injury, which happens when a pomegranate is stored below about 41°F for too long. The fruit may also show brown pitting on the skin and become more prone to decay. A few brownish arils near the skin can be picked out, but if the browning is widespread, the fruit is past its prime.
How Long Pomegranates Stay Good
Whole pomegranates last one to two weeks at room temperature when kept out of direct sunlight. Refrigerating them extends that window to roughly two months, which is unusually long for a fresh fruit. Once you’ve removed the arils, store them in an airtight container in the fridge and use them within about five days.
If you’ve had a pomegranate sitting on your counter for a while, re-check it with the tap test before cutting in. A good pomegranate still sounds metallic and feels heavy. If it has started to feel light or sounds flat when tapped, the arils inside have likely dried out.
Buying at the Right Time
Fresh pomegranates hit peak season from late September through November in the Northern Hemisphere. During these months, you’ll find the widest selection and the best prices at grocery stores and farmers’ markets. Pomegranates sold outside this window are either imported from the Southern Hemisphere or have been in cold storage, which is fine but increases the chance of chilling injury and flavor loss. For the best odds of picking a great pomegranate, shop in October and November and use the shape, weight, and tap tests to find the ripest fruit on the shelf.
