It's never tough to drink fresh beer, but it can be tough to keep it fresh after opening a growler. This Mini CO2 Regulator promises to keep things fresh, utilizing an easy to replace food grade CO2 cartridge that slides easily into the tap handle to keep the contents of the growler carbonated and ready to consume. It comes with a 64oz stainless steel growler, with choices ranging from wood and leather carrying handles, to a charcoal colored carbon fiber cover plate. And if you're not a beer drinker, it's perfect for Kombucha and coffee too.
