How To Store Oats Long-Term

Choosing the right type of oats

Steel-cut oats

Steel-cut oats are whole oat groats that have been chopped into pieces using steel blades. They have a chewy texture and nutty flavor. Steel-cut oats take longer to cook compared to other types of oats, but they retain their shape and texture better. They are a great choice for those who prefer a heartier and more textured oatmeal.

Rolled oats

Rolled oats, also known as old-fashioned oats, are steamed and then flattened with large rollers. This process helps to shorten the cooking time of oats. Rolled oats have a softer and smoother texture compared to steel-cut oats. They are versatile and can be used in various recipes such as cookies, muffins, and granola bars.

Instant oats

Instant oats, also called quick oats, are the most processed form of oats. They are pre-cooked and then dried, making them the quickest to prepare. Instant oats have a finer texture and tend to become mushy when cooked for too long. They are convenient for busy individuals who want a quick breakfast option.

Oat groats

Oat groats are the whole, unprocessed oat kernels with the husk removed. They have a chewy texture and a nutty flavor. Oat groats take the longest to cook among all the oat varieties but offer the most nutritional benefits since they are the least processed.

They are a good choice for those seeking a healthier option and don’t mind the longer cooking time. Choosing the right type of oats depends on personal preference, texture desired, and cooking time available. Each type has its unique characteristics and can be used in different recipes.

Preparing oats for long-term storage

Removing moisture

Before storing oats for the long term, it is crucial to remove any moisture to prevent spoilage and the growth of molds. Make sure the oats are completely dry before packaging them.

Removing debris

Inspect the oats for any foreign objects or debris and remove them. It is essential to store clean oats to maintain their quality during storage.

Sealing oats in airtight containers

To preserve the freshness and extend the shelf life of oats, use airtight containers to store them. This prevents moisture, pests, and oxygen from entering and damaging the oats.

Using oxygen absorbers

Adding oxygen absorbers to the storage containers can further enhance the longevity of stored oats. Oxygen absorbers remove the oxygen present in the container, which helps in preventing the growth of insects and molds.

Properly preparing oats for long-term storage ensures that they remain fresh and can be stored for an extended period.

Selecting appropriate storage containers

Glass jars

Glass jars are an excellent choice for storing oats as they are non-porous and do not absorb odors. They provide a clear view of the contents and are easy to clean. However, they may not be suitable for bulk storage due to limited capacity.

Plastic buckets

Plastic buckets are a popular choice for bulk oat storage. They are durable, lightweight, and can withstand different storage conditions. Look for food-grade plastic buckets that are BPA-free and have a tight-fitting lid to keep out moisture and pests.

Mylar bags

Mylar bags are a flexible and lightweight option for storing oats. They provide an additional layer of protection against moisture, light, and pests. Mylar bags should be heat sealed to maintain airtightness.

Food-grade storage containers

Food-grade storage containers made of materials like high-density polyethylene (HDPE) or polypropylene (PP) are ideal for storing oats. They are safe for food contact and offer excellent durability and resistance to moisture and pests.

Choosing the right storage container depends on the amount of oats being stored, the storage space available, and personal preference.

Maintaining ideal storage conditions


Oats should be stored in a cool and dry place to prevent spoilage. The ideal temperature range for oat storage is between 40°F and 60°F (4°C and 16°C). Avoid storing oats in areas that are exposed to high temperatures or fluctuations in temperature.


Moisture is the enemy of long-term oat storage. Aim for a humidity level below 15% to prevent spoilage and the growth of molds. Using moisture absorbers in the storage containers can help maintain the desired humidity level.

Light exposure

Oats should be stored in a dark place away from direct sunlight and artificial light sources. Light can degrade the quality of oats and shorten their shelf life. Use opaque or dark-colored containers to prevent light exposure.

Avoiding pests

Protect stored oats from pests by regularly inspecting the storage area for signs of infestation. Keep the storage area clean, and use pest deterrents like bay leaves or cedar chips.

Sealing the storage containers tightly and using oxygen absorbers also helps prevent pests from accessing the oats. Maintaining ideal storage conditions is essential to ensure the longevity of stored oats and preserve their quality.

Freezing oats for long-term storage

Packaging oats properly

Before freezing oats, ensure they are properly packaged to prevent moisture and freezer burn. Divide the oats into smaller portions and place them in airtight freezer bags or containers. Squeeze out any excess air before sealing.

Labeling and dating

Label each package with the date of freezing to keep track of their freshness. Use a permanent marker to write the date on the packaging.

Freezing duration and thawing process

Oats can be stored in the freezer for up to 12 months. When ready to use, remove the desired portion from the freezer and thaw in the refrigerator overnight. Thawed oats can be cooked as usual.

Freezing oats is a viable option for long-term storage, especially for those who have limited space or live in areas with high humidity.

How long can oats be stored?

Shelf life of different types of oats

Different types of oats have varying shelf lives. Steel-cut oats and oat groats can be stored for up to 2 years if properly stored. Rolled oats and instant oats have a slightly shorter shelf life, typically around 1 to 2 years. It is recommended to consume the oats within their shelf life for the best quality.

Factors affecting oat storage life

Several factors can affect the storage life of oats, including temperature, humidity, light exposure, and the presence of pests. Proper storage conditions and regular inspections can help prolong the shelf life of stored oats.

It is important to monitor the condition of stored oats and discard any that show signs of spoilage or pests.

Inspecting stored oats

Checking for signs of spoilage

Removing pests or molds

If pests or molds are discovered in the stored oats, take immediate action to prevent further contamination. Remove the affected oats and inspect surrounding containers for any signs of infestation. Thoroughly clean the storage area and consider using pest control measures if necessary.

Properly disposing of spoiled oats

If any oats are deemed unfit for consumption, dispose of them properly. Do not use spoiled oats for cooking or feeding animals, as they can cause illness.

Regular inspection and proper disposal of spoiled oats ensure the quality and safety of the remaining stored oats.

Using stored oats effectively

Rotation system

Implement a rotation system to ensure that older oats are used first. This prevents the oats from sitting in storage for too long and helps maintain a fresh supply.

Using stored oats effectively allows for a continuous supply of nutritious meals and snacks.

Types of proper oat storage

Short-term storage

Short-term storage refers to storing oats for a few weeks to a few months. In this case, airtight containers, such as glass jars or food-grade storage containers, can be used. It is important to ensure the oats are sealed properly to prevent moisture and pest infestation.

Medium-term storage

Medium-term storage involves storing oats for several months up to a year. Plastic buckets or Mylar bags with oxygen absorbers are recommended for medium-term storage. These containers provide a higher level of protection against moisture, light, and pests.

Long-term storage

Long-term storage refers to storing oats for over a year. Mylar bags or food-grade storage containers with oxygen absorbers are the preferred choice for long-term storage. These containers offer the necessary protection to keep the oats fresh for an extended period.
