  • Hi Simba,

    thanks again for elaborating!

    Can't really watch those videos though to be honest as that guy's voice is just making my head hurt unfortunately.

    Vitamin B12 can only be produced by bacteria.
    It cannot be produced by any yeast cells. So if there is some B12 in nutritional yeast or in beer, it is always added or due to bacterial contamination in the production which is highly unlikely.
    Some of the other B vitamins can be produced by yeast, but not B12.

    ..so I did actually contact the brewery and asked them about this; here's what they tell me:

    Unsere Weißbierspezialitäten werden nach dem Bayerischen Reinheitsgebot hergestellt, weshalb wir nur die Rohstoffe Wasser, Weizen- und Gerstenmalz, Hefe und Hopfen verwenden. Im Falle von ERDINGER Alkoholfrei wird außerdem noch die aus dem Brauprozess gewonnene Gärungskohlensäure als Zutat genutzt. Zusätze, z. B. von Vitaminen, sind nicht erlaubt, weshalb die wertvollen Vitamine in unseren Weißbieren von Natur aus enthalten sind. Das Vitamin B12 in ERDINGER Alkoholfrei wird über den natürlich vorkommenden mikrobiellen Besatz auf Weizen und Gerste bzw. Malz gebildet. Für dieses Vitamin B12 wurde durch renommierte Wissenschaftler eine Bioverfügbarkeit beschrieben.

    "Our wheat beer specialties are made observing the bavarian purity law (...) which forbids adding supplements, including vitamins (...).
    The vitamin B12 in Erdinger alcohol-free wheat beer is formed by microbial growth on wheat, barley and malt.
    Renowned scientists have attested the bioavailability of this vitamin B12"

  • Yeah, I would consider that an untrustworthy industry answer.

    Drink the beer because you like it, not because of the B12

    Also, all of the videos are subtitles in multiple languages and transcribed.

  • would consider that an untrustworthy industry answer

    ..not sure, Bavarians really don't fuck around with their Reinheitsgebot so can't imagine them really addings stuff like vitamins to be honest.
