    Good morning all, has anyone on MBAA any experience in using Nagardo as a Natural preservative in Kegged Beer to prevent reinfection / diastaticus infections? Are there any limitations to using the preservative outside of the USA where it is approved?

    I am assuming you aren't talking about NA beer, since you mentioned it is kegged. I am not an expert on Nagardo, but I was under the impression it was only designed for alcohol free beverages.  I haven't personally ever seen it used in alcoholic ones, but I have seen it in things like iced teas and Capri Sun.  It is usually listed as mushroom extract on the label.  

    I think Velcorin, which is sold by the same company, is what you would use for alcoholic beverages.  I would reach out to a salesperson at Lanxess to discuss your particular application, though.

    Velcorin (dimethyldicarbonate) isn't used in beers for several reasons:

    -The beverage pH must be between 2 and 4 for effective hydrolyzation, and most beers are above that.

    -Needs special dosing equipment, which is pricey.

    -It is toxic prior to dosing, so there is a risk to people handling it.

    -Needs a low cell count (less than 500 cfu/mL).

    It is great for cider and wine, but not so much for beer.

    Looking forward to more conversation in here about shrooms!

    I was also told by someone at Scott Labs that Velcorin isn't suitable for NA beer application because the protein content in beer interferes with it's mode of action.  I have heard some claim that they have used it successfully, but if the people supplying Velcorin are saying that it isn't suitable for beer applications I'm inclined to believe them.  I was told it's well suited to seltzers, wine, RTD cocktails and the like since they are low pH and low protein content.

    I have no experience with Nagardo, but as Ben said, I believe it is not certified to be used in alcoholic products. You might want to look into a newer product called Chiber by Chinova Bioworks. It is a fiber that is derived from white button mushroom stems (similar to Nagardo I believe) that can be added to alcoholic beverages. We haven't used it in any of our products but I have tested it out in bench top trials with success at showing protection against Saccharomyces, Brettanomyces, and Lactobacillus.

    I was informed by a company representative that: "Nagardo is not currently registered for alcoholic beverages nor NA beer. We hope to have this completed by end of next year".   For further information, please contact michael.rumsey@lanxess.com

    Cheers,
