The Dreamfarm company was founded by Alexander Gransbury in 2003. Alexander always tried to find a way to get rid of the used coffee grinds from his espresso machine at home. He built his first-ever prototype out of a PVC pipe and a construction bolt. This invention lead to the company producing a coffee grind knockbox called the Grindenstein. The device gained popularity a year later and is in stores worldwide. Copa Habana has this nifty device that can store your espresso ground without any hassle.
