Store whole garlic bulbs in a cool, dry, dark place with good airflow, such as a mesh bag or an open basket in the pantry, not in the fridge. Kept this way at about 16°C (60°F), bulbs can last 3 to 5 months, according to the University of California’s food safety guide. Once you break a bulb or peel the cloves, keep them in the fridge and use them within days, or freeze them.
One rule matters more than the rest: never keep homemade garlic in oil at room temperature. It can grow the bacteria that cause botulism. This guide covers every way to store garlic (whole, peeled, chopped, frozen, dried, in vinegar and in oil), how long each lasts, and how to tell when garlic has gone bad.
- Whole bulbs: cool, dry, dark and airy; 3 to 5 months at about 16°C (60°F)
- Ordinary room or pantry: about 1 month (USDA FoodKeeper)
- Peeled or loose cloves: fridge, 3 to 14 days (USDA FoodKeeper)
- Frozen: whole cloves, chopped garlic or a garlic-oil purée
- Garlic in oil: fridge for no more than 4 days, or the freezer; never at room temperature
How to store whole garlic bulbs
Keep whole, unbroken bulbs somewhere cool, dry, dark and well ventilated. A mesh bag, a wire basket or a paper bag with holes all work. The University of California’s guide on garlic (ANR Publication 8568, by food safety specialist Linda J. Harris) says bulbs keep for 3 to 5 months under cool (16°C or 60°F), dry, dark conditions.
In a normal kitchen that is warmer, expect less. The USDA’s FoodKeeper guide gives about 1 month for unbroken bulbs in the pantry, and Michigan State University Extension says the same: about a month, depending on the garlic’s age and variety.
- Do: keep the papery skin on, keep bulbs whole until you need them, and check them often.
- Don’t: seal bulbs in an airtight bag or box (the guides recommend open or loosely covered containers with airflow), or keep them in sunlight or near heat such as the stove.
Should you keep garlic in the fridge?
Not whole bulbs. The University of California guide says a home fridge (about 4°C or 40°F) is not suitable for long-term garlic storage because that temperature makes garlic sprout. The fridge is the right place for loose or peeled cloves, chopped garlic, and garlic in oil.
How long does garlic last?
| Type of garlic | Where to keep it | How long it lasts |
|---|---|---|
| Whole bulb, ideal conditions | Cool (16°C / 60°F), dry, dark, airy | 3 to 5 months |
| Whole bulb, normal pantry | Pantry or cupboard, in a mesh or open container | About 1 month |
| Loose or peeled cloves | Fridge, in a covered container | 3 to 14 days |
| Homemade garlic in oil | Fridge at 4°C (40°F) or below | No more than 4 days |
| Homemade garlic in oil | Freezer | Several months |
| Peeled cloves in wine or vinegar | Fridge | About 4 months |
| Dried garlic | Airtight container, room temperature or freezer | Long term, if kept fully dry |
| Garlic powder | Pantry, closed container | 3 to 4 years (best quality) |
A broken bulb does not last long. Michigan State University Extension says breaking the bulb cuts its shelf life to just a few days, so only take off the cloves you need.
How to store peeled garlic
Put peeled cloves in a small covered container or jar and keep them in the fridge. The USDA FoodKeeper gives 3 to 14 days for individual cloves in the fridge. For longer, freeze them. Shop-bought jars of chopped garlic are different: follow the storage instructions on the label once you open the jar.
How to freeze garlic
Freezing is the easiest way to keep garlic for months. The University of California guide gives three methods:
- Chopped: chop the garlic, wrap it tightly in a freezer bag or plastic wrap, and freeze. Break or grate off what you need.
- Whole cloves: put whole bulbs or cloves, peeled or unpeeled, in a freezer bag or box. Take out cloves as you need them.
- Garlic-oil purée: blend peeled cloves with oil (2 parts oil to 1 part garlic) and freeze it straight away in an airtight container. It stays soft enough to scoop. Never leave this mixture at room temperature.
Frozen garlic is best for cooking, not for eating raw. Michigan State University Extension notes that garlic can taste stronger and more bitter after freezing.
Is garlic in oil safe? The botulism rule
Homemade garlic in oil is safe only if you keep it cold. Store it in the fridge at 4°C (40°F) or below and use it within 4 days, or freeze it for several months. Never keep it at room temperature.
The reason is botulism. Garlic is a low-acid food, and oil keeps air out. At room temperature, this mix gives Clostridium botulinum bacteria what they need to grow and make toxin. The University of California guide says at least four botulism outbreaks linked to garlic in oil were reported in North America in the late 1980s and 1990s, including outbreaks in 1991 and 1999 linked to garlic in oil made at home. The US Centers for Disease Control and Prevention (CDC) warns that you cannot see, smell or taste the toxin that causes botulism, and it also says to refrigerate homemade oils made with garlic or herbs. The same risk applies to roasted garlic stored in oil.
- Make garlic oil in small amounts and label the jar with the date.
- Shop-bought garlic in oil is made with added acid (citric or phosphoric acid) to make it safe. Follow the label once you open it.
- Fully dried garlic can be used to flavour oil, as long as it stays completely dry.
- The University of Idaho has tested a home method for acidifying chopped garlic with citric acid before adding oil. Only use a tested recipe like that one; lemon juice and vinegar were not tested for this.
How to store garlic in vinegar or wine
Peeled cloves can be covered in undiluted (full-strength) wine or vinegar and kept in the fridge for about 4 months. The acid stops botulism bacteria from growing. Dry white or red wine and white or wine vinegar work well. Keep the jar in the fridge, because at room temperature it will soon grow mould. Throw away both the garlic and the liquid if you see mould or yeast on top.
How to dry garlic
Use fresh, firm cloves with no bruises. Peel them and cut them in half lengthwise. The University of California guide says to dry them in a food dehydrator at 60°C (140°F) for 2 hours, then at 55°C (130°F) for another 4 to 6 hours, until they are crisp and snap when bent. Store dried garlic in an airtight container. You can grind it into garlic powder, and mix 4 parts salt with 1 part garlic powder to make garlic salt.
How to tell if garlic has gone bad
- Throw it away: cloves that are mouldy, soft, mushy, spongy or crumbly.
- Past its best but safe: cloves that are shrivelled or sprouting. The University of California guide says neither is harmful, just lower in quality. You can cut a sprouted clove in half and remove the green shoot.
- Blue or green garlic: garlic can turn blue or green in vinegar or when pickled. The guides say this is a natural colour change and is still safe to eat.
When you buy garlic, choose bulbs that are firm, heavy for their size and have tight, dry, papery skin. Avoid bulbs with soft spots, mould or green shoots.

Frequently asked questions
Should garlic be refrigerated?
Whole bulbs should not; the cold makes them sprout. Keep whole bulbs in a cool, dry, dark, airy place. Refrigerate peeled or loose cloves, chopped garlic and garlic in oil.
How long does garlic last at room temperature?
Whole, unbroken bulbs last about a month in a normal pantry, and 3 to 5 months in cool (about 16°C or 60°F), dry, dark conditions. A broken bulb lasts only a few days.
How long do peeled garlic cloves last in the fridge?
The USDA FoodKeeper gives 3 to 14 days for individual cloves in the fridge. Freeze them if you need them to last longer.
Can you freeze garlic?
Yes. Freeze whole cloves, chopped garlic, or a purée of garlic and oil. Frozen garlic is best for cooking, as it can taste stronger and a little bitter.
How long does homemade garlic oil last?
No more than 4 days in the fridge at 4°C (40°F) or below, or several months in the freezer. Never keep it at room temperature, because of the botulism risk.
Is sprouted garlic safe to eat?
Yes. Sprouting is not harmful, but the garlic is past its best. Cut the clove in half and remove the green shoot if you like.
Why did my garlic turn blue or green?
Natural pigments in garlic can change colour in acid, such as vinegar or pickling liquid. It is still safe to eat.
