Scientists have discovered that some beers are bursting with probiotic microbes — bacteria and yeast credited with a host of health benefits from combating obesity to getting a better night’s sleep.
Examples include the strong Belgian beers Echt Kriekenbier, Hoegaarden and Westmalle Tripel which are rich in probiotic yeast.
Africa Tembelea understands that unlike most beers, they are fermented twice — once in the brewery and again in the bottle.
The process increases the strength of the beer.
Importantly for health, in-bottle fermentation uses a different strain of yeast to that found in traditional pints.
It not only converts sugar into alcohol, but it produces acids that kill off harmful bacteria.
Professor Eric Claassen, a gut bacteria expert at Amsterdam University, said: “In high concentrations, alcohol is bad for the gut, but if you drink just one of these beers every day it would be very good for you.”
Research from the University of Nebraska, USA, also found some bottled beers contain up to 50 million probiotic or “good” bacteria.
Prof Claassen told an event held by probiotic drink maker Yakult: “In the Middle Ages, people made beer because the water was not drinkable.
“The yeast killed off bad bacteria in the water.”
