Kombucha, a probiotic fermented tea, is an age-old drink that is enjoying renewed popularity.

Kombucha, originally from China, has been around 2,500 years. Probiotics help with your gut system and allow your immune system to function properly.

Because it is fermented, Kombucha has 0.5% alcohol which is the same as nonalcoholic beer.

For this week's Made in Connecticut, News 12 visited East Coast Kombucha in South Norwalk.
