✔ Updated · shelf life, spoilage signs, crystallizing + storage
Pure honey is one of the few foods that can last for years, even decades. It can still spoil if water or dirt gets in, so here is how to tell and how to store it.
Pure honey does not really expire. Its high sugar, low moisture and natural acidity stop bacteria and mold from growing, so a sealed jar kept in a cool, dry pantry stays safe almost indefinitely. The best-by date, usually about 2 years, is for quality only. Honey can go bad if it absorbs water and ferments: throw it out if it smells sour or yeasty, foams or grows mold.
- Pantry: safe indefinitely when sealed; best quality within about 2 years.
- Crystallized honey is not spoiled; warm it gently to re-liquefy.
- Bad signs: sour or alcohol smell, foam, bubbles, mold or a watery layer.
- Never give honey to babies under 12 months (botulism risk).
Honey Shelf Life at a Glance
| Type of honey | Storage | How long it lasts |
|---|---|---|
| Pure honey, sealed | Pantry, cool and dry | Indefinitely; best quality about 2 years |
| Pure honey, opened | Pantry, lid tight | Indefinitely if kept dry and clean; best quality 1 to 2 years |
| Raw honey | Pantry | Same as above; crystallizes faster |
| Creamed (whipped) honey | Pantry | Same as above; stays thick and spreadable |
| Honeycomb | Pantry, sealed | Indefinitely; best within a year |
| Honey blends (syrups, flavored or "honey sauce") | Pantry or per label | Follow the best-by date; added water and ingredients can spoil |
| Honey butter or infused honey with fresh herbs | Fridge | Follow the label or about 1 to 2 weeks if homemade |
Why Honey Lasts So Long
Honey is about 80% sugar and only about 17 to 18% water. That is too little free water for bacteria, yeast or mold to grow. It is also acidic, with a pH of around 3.5 to 4.5, and bees add an enzyme that slowly produces small amounts of hydrogen peroxide.
That is why sealed honey can stay edible for decades. Archaeologists have reported finding pots of honey in ancient Egyptian tombs, although nobody recommends eating those.
Can Honey Expire? What the Date Means
The date on a honey jar is a best-by date, not a safety date. After it, honey is usually still safe, but it may darken, lose some aroma and crystallize. If it looks, smells and tastes normal, it is fine to eat.
The exception is honey blends and products with added water, fruit, herbs or dairy, which can spoil like other foods. Follow the label on those.
How to Tell If Honey Has Gone Bad
Honey spoils when it takes in moisture, usually from a loose lid, a wet spoon or humid air. Wild yeasts then start to ferment the sugars. Throw honey out if you notice:
- A sour, yeasty or alcohol-like smell or taste.
- Foam, fizz or lots of small bubbles on top.
- A thin, watery layer separating on the surface.
- Mold or anything fuzzy growing on top or around the lid.
- A bulging lid or pressure when you open it.
Crystallized Honey Is Not Spoiled
Crystallization is natural. Honey is a supersaturated sugar solution, so over time the glucose forms crystals and the honey turns pale, thick and grainy. Raw honey and some floral types, like clover, crystallize faster, and cold speeds it up. It is completely safe to eat.
How to Re-Liquefy Crystallized Honey
- Set the open glass jar in a bowl or pan of warm water, about 95 to 110°F (warm bath temperature, not boiling).
- Stir every few minutes until the crystals dissolve, topping up with warm water as it cools.
- For plastic bottles, spoon the honey into a glass jar first.
- Avoid microwaving on high or boiling: high heat darkens honey and dulls its flavor.
- Only warm what you will use soon; it will crystallize again over time.
How to Store Honey
- Keep it sealed: close the lid tightly so honey does not absorb moisture or odors.
- Cool and dry: store at room temperature (about 50 to 70°F) in a pantry, away from the stove and sunlight.
- Skip the fridge: cold makes honey crystallize faster. It is safe there, just harder to use.
- Freezing: works for long-term storage and stops crystallization, but it is not needed.
- Use a dry, clean spoon: water, crumbs or butter in the jar can start fermentation.
- Glass or food-safe plastic containers are best; avoid reactive metal containers.
Honey Safety: Babies Under 1
Never give honey, raw or pasteurized, or foods made with it to babies under 12 months old. Honey can carry Clostridium botulinum spores that can cause infant botulism, according to the CDC. Honey is fine for children over 1 and adults.

Frequently Asked Questions
Can honey expire?
Pure honey does not truly expire. Kept sealed in a cool, dry place, it stays safe almost indefinitely because its low moisture and acidity stop microbes from growing. The best-by date, often about 2 years after bottling, is about flavor and color, not safety.
Can you eat honey after the expiration date?
Yes, if it is pure honey and it looks, smells and tastes normal. Older honey may be darker, thicker or crystallized, which is harmless. Throw it out if it smells sour or alcoholic, foams, has a watery layer on top or shows any mold.
Does honey go bad once opened?
Opened honey lasts just as long, provided you keep it sealed and dry. Spoilage usually starts when water gets in from a wet spoon, a loose lid or humid air, which lets yeast ferment it. Always use a clean, dry utensil and close the jar tightly.
Is crystallized honey bad?
No. Crystallization is a natural process in which the sugars form crystals, making honey thick, cloudy and grainy. It is safe to eat as it is. To make it runny again, stand the open jar in warm water and stir until the crystals dissolve.
Should honey be refrigerated?
No. Honey keeps best at room temperature in a cool, dry pantry. The fridge will not make it last longer, and cold makes it crystallize faster. Freezing is fine for long-term storage, but it is not necessary for pure honey.
