What is the shelf life of hemp oil
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.
Pressing hemp oil to extend shelf life
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.
Sealed jugs devoid of oxygen extend shelf life
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.
Cold storage of the oil extends shelf life
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.
Keep your oil cold and out of the light
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.

Cold Pressed or Refined Hemp Oil?
Hemp oil is referred to as the most perfectly balanced oil created by nature. This is due to the perfect balance of unsaturated Omega 3 and 6 fatty acids that cannot be found anywhere else. Hemp oil is also rich in vitamins, antioxidants, and other health beneficial substances. However, this only applies if the oil is cold pressed, as only unrefined hemp oil preserves all the nutrients contained in the hemp seed.
How is unrefined hemp oil made?
Unrefined, cold pressed hemp oil is obtained from hemp seeds with mechanical extraction at a low temperature that doesn’t exceed 40 degrees Celsius. Cold pressed hemp oil is not chemically cleaned or bleached and the sediments are removed mechanically using filtration.
The shorter shelf life of cold pressed oil
Due to the lack of chemical treatment and absence of high temperatures, the active substances found in the seeds of the plant are also preserved in cold pressed oils. Because of this, the oil has a shorter shelf life and needs to be stored in cold places, and the supply chain between the manufacturer and the end consumer needs to be shortened as well. Incorrect storage and irregularities in transportation can make the cold pressed oil go bad faster. The first sign alerting you to any irregularities will be an unusual odor. Properly stored, fresh cold pressed hemp oil has a strong green color, as well as a strong but pleasant smell that resembles a mixture of freshly mowed grass and nuts.
Why is unrefined oil better than refined oil?
Refined oil has a cleaner appearance, with a lighter color, and does not contain small particles. Refining is a relatively complex process that includes treatment with chemical compounds and at high temperatures, reaching up to 270 degrees Celsius. The process removes most of the vitamins contained in the oil, as well as other health beneficial substances. Also lost in the process are Omega 3 and 6 fatty acids, which are the ingredients that give hemp oil the title of the most balanced oil. Refined hemp oil is primarily used in cosmetics, the production of various ointments and even plastics.
Two main reasons most cosmetics manufacturers decide to use refined oils
- Refined oils last longer allowing for a longer supply chain between production and the end consumer, higher volumes of stock and lower risk for the manufacturer
- Refined hemp oil is significantly cheaper than unrefined oil
At Hemptouch, we swear by unrefined, Cold Pressed Hemp Oil
All our products are based exclusively on cold pressed hemp oil. This is the only way to preserve all the beneficial substances that make hemp oil so popular in skin care. We realize this makes the shelf life of our products much shorter and that it affects the supply chain, which is a challenge in business, however, this helps us ensure our products are always fresh and of the highest quality.
Because we want to have full control over the ingredients used in our products, we make the cold pressed oil from our own hemp, grown on our field in Novo mesto, where we can observe its growth from seed to full-grown plant.
