As for the aforementioned "unique beer concentrate," SodaStream said it's releasing a light beer called Blondie that has a "smooth authentic taste, and a hop filled aroma," per the press release. The resulting beer contains 4.5% alcohol by volume (ABV), and one liter of the concentrate will allow you to make about three liters of beer. Apparently, the whole "brewing" process is done in seconds.
If beer made from sparkling water and concentrate sounds appealing to you, you'll likely have to wait a while before you can get your hands on the Beer Bar machine as SodaStream said it will only launch in Germany and Switzerland at first, with additional markets coming later this year. (We reached out to SodaStream to see when you can expect to see it in the US). Of course, there are already similar gadgets, like the Fizzics machine, on the market, among others.
