Miller Lite has introduced the Big Green Kegg, a limited edition product designed to complement the Big Green Egg grill. The Kegg, which holds a quarter barrel of beer (83 12-ounce beers), is insulated to keep beverages cold while grilling. Available for a limited time from May 28th to the 30th, the Big Green Kegg will be sold online for $350, with a contest offering additional chances to win one.
