Abstract: A container comprising an inner bottle and an outer bottle each preferably made of stainless steel. The bottles nested and each having a neck portion and connected at their necks so as to minimize thermal conductivity between the inner bottle and outer bottle and to form an air tight enclosed vacuum between the inner bottle and outer bottle. Preferably the outer bottle has a volume of between 102% and 130% of the inner bottle and the inner bottle has a volume of between 26 and 80 ounces. The container can be sealed and reused to permit efficient use as a growler for beer.
