The idea for this probiotic brew was first proposed by a student in the University's Food Science and Technology program, who worked alongside school faculty for about nine months to perfect the recipe: a sour beer that contains roughly 3.5% alcohol.
It was a unique challenge since beers contain hop acids which prevent the growth and survival of probiotics (and is part of the reason there aren't currently any probiotic beers on the market). To allow for live probiotics to survive in the final product, they had to modify the conventional brewing and fermentation process.
Specifically, it contains a probiotic strain known as "lactobacillus paracasei L26," which apart from having a sexy name that just rolls off the tongue, has been shown to neutralize toxins and viruses, as well as regulate the immune system.
