The short answer is, if stored correctly, an unopened bottle of our hemp oil will last 14 months from the date of production. The long answer is there are several factors that can influence the shelf life of hemp oil. The major ones are how the seed is pressed, how the oil is packaged and how the oil is stored.
Since the essential fatty acids in hemp are very susceptible to degradation and rancidity, producing a shelf stable oil starts with being very careful at the production stage. By ensuring that the oil has had minimal exposure to heat and to oxygen, the production of the oil ensures that the goodness that was available in the raw seed is retained in our virgin cold-pressed hemp oil. We do this through a production process that protects the essential fatty acids from exposure to oxygen by replacing the “air” in the production environment with pure nitrogen. In addition to protecting the oil from oxidation, we also ensure that the oil is kept well below the allowable temperatures required to be able to call the oil cold-pressed. These two factors enable us to produce a product that is as close as possible to mimicking the seed in it’s ability to safeguard the oil. You might consider our method better, since seeds can get broken, allowing oxygen to access the oils.
The oxygen free environment doesn’t stop at the pressing stage, we continue it right through to the bottling stage where the oil is maintained oxygen free and then the last bit of space in the top of the filled bottle is also replaced with nitrogen before the bottle is sealed with a foil topper and the lid is put on. These extra steps ensure that the oil will remain fresh for a long period of time after it has been placed in the bottle, literally for many months allowing us to set a best before date of 14 months from the date of manufacture.
Keep your oil cold. While we maintain an environment that is consistently lower than 15 C for short term storage of the products, we highly recommend you storing your oil in the freezer for longer term storage. One of the many wonderful benefits of hemp oil is that it will not turn to a solid at the temperatures reached in your home freezer so you can keep you oil there and it will still pour for you. There may be some separation of the naturally occurring waxes but this will just result in some cloudiness and is not something to be concerned about. It will not affect flavour or consistency when the oil warms.
The two things you need to be aware of after you get your oil is that you should keep it cool and out of the sunlight. Store the oil in the freezer for long term storage and in the fridge in the short term. The oil can withstand moderate temperatures, for instance while being shipped, without any significant degradation. For long term storage, just ensure you maintain a cold temperature.
