What is Garlic?

Garlic is a bulbous flowering vegetable in the onion and allium family. It’s closely related to leeks, chives, onions, and shallots. Garlic is used as a flavoring for many dishes and has medicinal properties. Most of the world’s garlic comes from China.

How to Buy – Tips & Tricks

When buying fresh whole bulbs of garlic, you’ll want to look for the following indicators that will help indicate that the garlic is fresh. Here’s how to choose fresh garlic at the grocery store:

White skin. The garlic should be wrapped in a nice white papery skin. Any other colors such as gray, brown, or yellow would indicate that the garlic is old.

Firmness. Give it the firmness test by gently squeezing the garlic between your fingers. If the garlic is firm, that means it’s nice and fresh. If it’s squishy then the garlic is old.

No sprouts. Look for garlic that’s not sprouted. Sprouts on your head of garlic also indicate age.

Where to Buy

Fresh garlic can be found in supermarkets and grocery stores in the United States, typically located in the produce section near the potatoes. Minced garlic can be found sold in jars typically near the salad dressings and condiments or spices and seasonings.

How Long Does Fresh Whole Bulb of Garlic Last?

The length of time fresh whole bulb garlic will last depends on a few factors such as its storage conditions and its freshness.

Whole bulb garlic can last anywhere from a few days to a year, depending on how it’s stored. We estimate that when stored in a cool, dry, dark place such as a pantry, whole garlic will generally last between 3-5 months.

How Long Does Processed Garlic Last?

Fresh garlic that’s been processed and peeled or chopped will typically last about 1 week when stored in an airtight container in the refrigerator and will last about 10-12 months in the freezer.

Commercial prepared jarred garlic sold as whole, cloves, or minced, traditionally contains citric acid to make it last longer. You should use the best if used by date when determining how long commercial garlic will last and store it sealed in a container in the refrigerator after it’s opened.

How to Tell When Garlic Has Gone Bad

There are three mains signs that you can look for to know if your garlic has gone bad. Just use your senses to know signs of bad garlic:

Look.  
Examine the appearance of your fresh bulbs or cloves of garlic.
Do brown spots or mold appear?
Does it appear more yellow or brown in color rather than white?
Does it have green shoots emerging? 
If you answered “yes” to any of these questions, your garlic has likely gone bad and needs to be thrown away.

Smell.  
The smell of fresh garlic is one that’s pungent, mellow, and spicy.  If your garlic smells sour or off in any way, don’t use it and throw it out.

Feel.  
Gently squeeze your garlic between your finger and your thumb. If it feels nice and firm and has none of the other key indicators listed here, then it’s still good.

However, if your garlic feels soft, then it’s likely spoiled and shouldn’t be used.
