Why Should Coffee Bag Size Be Chosen by Volume Instead of Weight Alone?Coffee bag size should not be selected based only on the weight printed on the package. The same weight of coffee can occupy different amounts of space depending on the roast level and whether the coffee is sold as whole beans or ground coffee.Light roast coffee beans are generally denser and occupy less volume. Dark roast beans, on the other hand, lose more moisture during roasting and develop a more expanded structure, which means the same weight can take up more space.The physical form of the coffee also matters. Ground coffee generally has a higher bulk density than whole beans because there are fewer air spaces between particles. As a result, 250g of ground coffee and 250g of whole beans may not require exactly the same internal packaging space.https://www.customshinepack.com/blogs/coffee-bag-sizes
