Everyone knows that the standard glass growler you get at most breweries is susceptible to temperature change, UV contamination and freshness issues. Ceramic growlers are a great step up, but they’ve got nothing on this double-walled, vacuum insulated growler from MIRA. Made with 18/8 stainless steel and sealed with an air-tight, screw-on seal on top, the MIRA Beer Growler will keep 64oz of beer for you, friends and family cold for up to twenty-four hours. We can’t understand why you’d use this for anything other than a large pour from your favorite local brewery, but it can also keep hot beverages (coffee, cocoa, spiked cider, etc.) steaming for up to 12 hours.
