I'm a maker Brewers, Cider makers and Vintners look to petainerKeg™ as an alternative to the massive historical capital investment in steel kegs. This option allows makers to send their product into new markets without risk and reduced cost. I'm a brand owner Brand Owners will enjoy opportunities in new markets as well as the brand exposure via packaging. I'm a distributor International distribution companies benefit from the classic keg with reduced storage, no return costs and reduced cost and theft that can open up new markets to them. I'm in the trade Publicans, Restaurateurs and Hoteliers can now reduce storage as petainerKeg™ can be crushed and recycled in one piece. The taste quality of the product is as good as, if not better, than the same product in steel keg.
