How To Store Nuts Long Term

To store nuts long term, store them in the fridge to last for six months. Store them in the freezer to last for up to a year. And if you’re storing them at room temperature, seal them correctly, and store them in a dark place to last for 3 months.

Use airtight containers or vacuum-sealed bags for added protection. Label your containers to keep track of their freshness.

However, nuts will still get rancid if kept for more than two years – even stored properly. It’s best to only store as many as you can use in this period.


Storage Basics Of Nuts Preservation

Proper storage is essential for keeping nuts fresh and preserving their flavor and nutritional value. Ideal containers and the right environmental conditions are key factors in ensuring that your nuts stay fresh for extended periods.

Now, let’s delve into the specific environmental conditions you should be mindful of to keep your nuts in peak condition.


A cool environment significantly lengthens the shelf-life of stored nuts. So you should store nuts long term in a cool place and keep them away from excessive heat, as this can cause the oils in nuts to go rancid. Look for an ideal storage temperature of around 60°F (16°C) or lower.


Storing your nuts in a dark place ensures they maintain their natural oils and flavors. Exposure to sunlight can also cause nuts to spoil faster. Store them in places, such as a pantry, cupboard, or drawer.


A dry area is crucial for avoiding mold and spoilage. Do not store nuts long term in humid locations such as a basement or under a sink.


Keep nuts away from strong-smelling foods to avoid flavor contamination. Nuts can absorb odors from nearby foods, which may affect their taste. Store them away from onions, coffee, or cleaning supplies.


Storing nuts separately prevents flavor mingling and allergic reactions. Place different types of nuts in different containers to avoid cross-contamination. Individual storage of different nuts also helps maintain their distinct flavors.

  • Airtight plastic storage containers

  • Vacuum-sealed bags

Which Nut Varieties Are Best for Long Term Storage?

The shelf life and quality of various nut varieties can vary significantly, influenced by factors like oil content and storage conditions. This is why some nuts are better suited for long term storage than others.

If you’re looking for the best nuts to stock in your pantry. Here are some of the best nuts for long term storage:


Glass jars are excellent for almonds because they are airtight and non-porous. Choose raw, unshelled almonds with low oil content and a hard shell. Store them in a dark place or in the fridge to make them last for up to two years.


For walnuts, choosing to store unshelled walnuts can last for up to a year.  Like almonds, unshelled walnuts have very low natural oil content. Ziplock bags work best for walnuts because they are convenient and moisture-resistant.


Hazelnuts, also known as filberts, store well in cloth bags due to their hard shell and lesser oil content. They make great nuts for long term storage. Hazelnuts can last a little over a year with proper storage.


Pecans have a moderately high oil content but can still be stored for a relatively long period. They do well in metal tins which offer both airtight and dark storage options. Unshelled pecans can last up to a year when stored in a cool, dark, and dry place.

Brazil nuts

Brazil nuts last longest when vacuum-sealed, inhibiting bacterial growth. They have a relatively low oil content and can last up to nine months when stored correctly.

Determining Nut Freshness: The Signs of Spoilage

Nuts contain unsaturated fats and oils that can become rancid over time. Nuts that go bad can affect their taste, texture, and quality. They degrade faster when exposed to heat, moisture, and air.

Knowing how to spot spoiled nuts is as essential as knowing how to store them. Here are the signs of nuts going bad:

  • Off or rancid smell: Unpleasant, sour, or musty odor.

  • Changes in texture: Soft, mushy, or rubbery, losing their natural crunch.

  • Mold growth: Discard immediately if you notice visible mold on the surface of the nuts.

  • Changes in taste: An off, bitter, or sour taste distinctly different from their natural flavor.

The Lifespan of Stored Nuts

The shelf life of nuts varies depending on factors such as the type of nut, storage conditions, and processing methods. Understanding the lifespan of different types of nuts helps you plan better for long term storage.

Shelled vs. Peeled Nuts

The shelf-life of shelled vs. peeled nuts differs significantly. Shelled nuts are bare nuts with their outer shells removed. Because of this, they have a shorter shelf life span than unshelled nuts due to lack of protection.

Removing the shell exposes the nut to more air and moisture, which can cause them to spoil faster. Unshelled nuts can last up to a year or more when stored correctly.

Roasted vs. Raw Nuts

Roasted nuts have a slightly shorter shelf life than raw nuts due to the cooking process. They can last up to six months, while raw nuts can last up to a year or even longer when stored properly.

Raw Brazil Nuts

Mixed vs. Pure Nuts

Mixed nuts have varying lifespans due to their diverse oil contents. The shelf life of mixed nuts is shorter. It also depends on the type of nuts and the processing and storage.

Whole Nuts vs. Sliced Nuts

Whole nuts will last longer than sliced or crushed nuts due to exposure to air. The crushing or slicing process creates more surface area, making them more exposed to air, moisture, and bacteria.
