What's better than beer straight from the tap? Not much. Unfortunately, lugging a keg around is quite the undertaking and generally not worth the effort for things like camping, tailgating, etc.
Kickstarter graduate DrinkTanks fixes this problem: a portable solution to keg beer. Their growler not only keeps the beer cold, but also carbonated, meaning it'll last days without going flat. It holds 64 ounces of frosty beer and comes with a tap hose. Genius.
