The quality of the beer was our top priority when we developed the Emmerald Green Cask. Your consumers expect the perfect pint every time and the GreenCask will ensure they get it! They are manufactured to the most rigorous quality standards. The casks are manufactured in HDPE (High Density PolyEthylene) to fully food approved standards. Our ISO 9001 certified precision construction ensures many years of reliable service. You’ll be proud to put your branding on the GreenCask and your customers will love the ease of handling and light weight.
