The neck label clearly states 0.0 % ALC.VOL.
The professors of the Bavarian University of Applied Sciences of Weihenstephan, research and training section 'Beer Academy', where German brew-masters are trained in order to receive their highly valued diplomas on 'high quality beer' production must have been quite surprised about the success of their professor colleagues at the Technical University of Berlin for producing 'zip' alcohol containing tasty premium beer.

Holsten Alkoholfrei Premium, 330 ml bottle;
in German supermarkets, one case of 24 bottles will cost you in range of 10 to 13 euros (U.S.-$14 to 18).
The Holsten-Brauerei (brewery) Hamburg, part of Carlsberg (DK), was savvy enough to purchase the Berlin patent. The trick of brewing this new beer type is a new mix of microorganisms that produce the typical flavor within the fermentation process but nearly without building alcohol that is the typical beer 'taste amplifier'.
The 0.0 % declaration technically means that the remaining alcohol concentration must be below 5/100th of a per cent v/v.
Well, the new Holsten product has already reached the market.
Good foam dispersion, a bright amber color, yummy, not too hoppy in its taste but not having that kind of sweetish expression occurring in other alc-free beer brands.
In comparison with Jever Fun, Flensburger Frei, Holsten Alkoholfrei is not so hoppy-bitter wheras Schöfferhofer Weizen (Wheat) alkoholfrei has more of this typical sweetness. It's just in between. It still tastes after some servings, preferably chilled from the fridge.
Conclusion:
A healthy isotonic product, containing quite a lot of amino-acids and vitamins.
It might be a good choice for (hobby) sports-persons who don't like the heavy sweetish taste of common isotonic sport beverages during or at the end of their exercises or work-outs.
For car drivers or even aircraft pilots, it's a neat stuff to stay sober while getting some essential vitamins.
