How do you recommend I store CanMar's Roasted Flax For Nutrition and for how long will it last once the bag is opened?

CanMar's Roasted Flax For Nutrition comes in a vacuum packed package. Left unopened and stored in a clean, dry place at room temperature the roasted flax will last one year. Once the vacuum seal is broken we recommend keeping the resealable package in a refrigerator and to consume the roasted flax within a 3-month period.
