NOBL Beverages in Seabrook built a cold brew empire one keg, one hospital donation, and one sleepless night at a time.

The 1.25 gallon serving keg is where you carbonate the beer, either with the included CO2 regulator and BB gun-like cartridges or using sugar. Original image has been replaced. Credit: Mashable ...

The Keg and Case Market building in St. Paul could soon see new life as the home of Fort Road Social, a proposed restaurant and entertainment spot from nearby St. Paul Tap owner Mike Tupa.

The NutriChef Pressurized Growler Tap System uses standard 16-gram CO2 cartridges. These cartridges are key to keeping your drinks at the right pressure, so everything stays fresh and pours smoothly.

If you have some beer leftover from a keg, it might still be drinkable. It all depends on how it is stored and what system you use to tap the keg.
