CO2 Mini Keg Systems

Pour fresh, perfectly carbonated draft beer at home with a CO2 mini keg system from Keg Smiths. Our systems use food-grade CO2 cartridges and an adjustable regulator to keep your beer pressurized and fresh for weeks — not hours.

Built with durable 304 stainless steel, each CO2 mini keg is designed for homebrewers, craft beer lovers, and anyone who wants portable draft beer on demand. Pair with our CO2 cartridges and accessories.

FAQ

How long does beer stay fresh in a CO2 mini keg?

With proper CO2 pressure, your beer stays carbonated and fresh for 2-4 weeks — far longer than a growler which goes flat within 24 hours.

How do I fill a mini keg?

Simply take your Keg Smiths keg to any local brewery's growler filling station, or transfer homebrew directly from your fermenter.

What size CO2 cartridges do I need?

Our systems use standard 16g threaded CO2 cartridges. Browse our CO2 cartridge selection for options including 74g for extended use.
