Great article [see link below] from our friends at Royal Coffee on their project to better understand the "trials" that coffee goes through during shipping. They put one data logger inside the grainpro liner and one data logger outside the grainpro but inside the jute bag.
Be sure to scroll down to the part where they show the graph of humidity -- there you will see what a difference grain-pro makes. Artisan Coffee uses grain-pro liners on almost all shipments!
