Kombucha has been the preferred probiotic drink for health-conscious individuals for many years. Its tangy, fermented flavor, combined with its supposed health benefits, has made it a favorite. But a new study from Brazil suggests there might be a new player on the probiotic scene—an apple-based fermented drink that could rival kombucha, offering similar health perks with a taste that many find more appealing.
Researchers from the Federal University of Ceara in Brazil created two new probiotic drinks using passion fruit and apple juices. They used the same culture of bacteria and yeast, called SCOBY (Symbiotic Culture of Bacteria and Yeast), which is commonly used in traditional kombucha production. Their study, published in the journal ACS Agricultural Science & Technology, found that the apple-based drink not only matched kombucha in terms of health benefits but also scored higher when it came to taste.
How was the new apple-based probiotic drink
made?
Led by researcher Socorro Vanesca Frota Gaban, the team aimed to find
alternatives to traditional kombucha that might appeal to a broader
audience. While kombucha is popular, its unique taste can be a barrier
for some people. The team hoped that by using fruit juices, they could
create drinks that offer the same probiotic health benefits as kombucha
but with a flavor profile more appealing to a wider range of consumers.
To make these new beverages, the researchers swapped the typical green
tea base of kombucha with either passion fruit juice or apple juice.
They added the SCOBY culture to the juice and let it ferment for 10 days
at room temperature, following the same method used for kombucha. The
two new drinks—PF(KLB) for the passion fruit version and A(KLB) for the
apple version—were then compared to a batch of traditional green tea
kombucha in terms of their chemical composition, antioxidant properties,
and taste.
Surprisingly, the apple-based drink,
A(KLB), emerged as a strong competitor. In terms of health benefits, it
contained similar amounts of phenolics and flavonoids—compounds known
for their antioxidant properties—to traditional kombucha. In fact, in
some measures of antioxidant activity, it even surpassed kombucha. These
compounds are essential because they help fight free radicals in the
body, reducing oxidative stress, which is linked to various diseases,
including cancer.
But what really sets A(KLB) apart is its taste. In a focus group of 12
participants, the apple-based drink was described as having a
refreshing, cider-like flavor with floral and citrus notes. It was
lightly carbonated, giving it a similar mouthfeel to popular soft
drinks, and had a mild alcoholic kick that added to its appeal. Many
tasters found it more palatable than traditional kombucha, which can
have a strong, vinegary taste that isn’t for everyone.
On the other hand, the passion fruit
version, PF(KLB), didn’t perform as well. While tasters appreciated its
aroma, many found it too sour and bitter, likely due to its higher
acidity and alcohol content. Its strong flavor was polarizing, with some
participants enjoying it but most finding it overwhelming compared to
the apple-based alternative. Traditional kombucha, meanwhile, fell
somewhere in between, with tasters noting its sweetness but also its
less pronounced flavor compared to the fruit-based drinks.

These results suggest that A(KLB) could be a
great alternative for people who want the health benefits of kombucha
but aren’t fans of its strong taste. Its familiar, apple-cider-like
flavor could make it more appealing to the average consumer, offering a
way to enjoy probiotics without sacrificing taste. As more people turn
to functional beverages—drinks that offer health benefits beyond basic
nutrition—A(KLB) could fill an important niche in the market.
However, there’s a catch. The alcohol content in these fruit-based
drinks is higher than in traditional kombucha. While kombucha usually
contains less than 0.5% alcohol by volume, making it non-alcoholic in
most countries, A(KLB) had an alcohol content of 1.65%, and PF(KLB) a
much higher 6.2%. This could pose challenges for commercialization, as
these drinks may need to be classified and sold as alcoholic beverages,
depending on local regulations.
Is this apple-based drink the new secret to
better digestion?
Despite this hurdle, the researchers remain optimistic about the future
of A(KLB). Its combination of health-promoting compounds, probiotic
benefits, and appealing taste make it a strong candidate for further
development. In today’s health-conscious world, consumers are always
looking for the next big thing in functional foods and beverages, and
A(KLB) could very well represent the next wave in probiotic drinks.
There’s also growing interest in diversifying the probiotic market.
Kombucha has been the star of the probiotic world for years, but as more
research is conducted into different fermentation processes and
ingredients, we could start to see a wider range of options available to
consumers. Drinks like A(KLB) offer an exciting new frontier, providing
the health benefits of probiotics in a more accessible format.
While more research is needed to fully
understand its long-term health impacts, A(KLB) represents an exciting
development in the world of functional beverages. Its combination of
health-promoting compounds, probiotic benefits, and crowd-pleasing taste
make it a strong contender for the next big health drink trend.
So, what's next for A(KLB)? The researchers are optimistic about its
future, but there's still work to be done. Further studies might explore
ways to reduce the alcohol content while maintaining the beneficial
properties. There's also the potential for experimenting with other
fruit juices or flavor combinations to create a whole range of probiotic
beverages.
As for us consumers, we'll have to wait a
bit before we can grab a bottle of A(KLB) off the shelf. But who knows?
In a few years, you might find yourself reaching for an apple-based
probiotic drink instead of your usual kombucha. And hey, if it tastes
like a delicious, slightly boozy apple cider while giving your gut a
health boost, that sounds like a win-win to me.
In the meantime, keep an eye out for new developments in the world of
probiotics and fermented beverages. The next big health drink revolution
might be just around the corner – and it might taste a whole lot better
than you'd expect.
