This is a normal occurrence in our peanut butter as we do not use any artificial emulsifiers or stabilizer in our product, over time the natural oil in the peanuts will separates from the peanut fibres and ascend to the top. Hence, it's really important to really stir it well each time before use. It's troublesome a little, but definitely really worth it as there’s no artificial additive in our peanut butter. Making it delicious and healthy!
