This Kegco 32 oz (1 Liter) double wall beer growler is constructed of durable food grade Stainless Steel and finished in Flat Black. The double wall, vacuum sealed design helps hold temperature by insulating the contents of the growler and allows it to be used with either hot or cold liquids. A vacuum is a space that contains no atoms which in turn eliminates conduction and convection allowing for the beverage inside to stay hot or cold depending on what you have put in there. The attached easy flip top cap closure makes it quick and easy to fill and has a silicone seal to ensure freshness. It's perfect for picking up beer from your local brewery or bringing your beer to parties and special events that restrict glass. What's more, if you want to have your own logo, signature or message written on the growler, custom screening is available for an additional charge. It's great for breweries, home brewers, wedding parties, company events and promotional items. Give us a call at 1-800-710-9939 for details.
