The price of kombucha varies depending on the brand and certifications, but they generally cost between $2-5 per bottle, which typically range from 12-16 ounces. Products that are USDA Certified Organic may come with a higher price tag and so will buying individual containers versus cases. The size of the bottle or can varies, so also take into consideration the price per serving. Also compare pricing between the different retailers listed, as pricing may change and items may be on sale on one retailer and not on another. Our top pick, Better Booch Kombucha Organic, Variety Pack was $40 for Pack of 9 ($0.28 per Fluid Ounce) when we published this article, and is USDA Organic and non-GMO.
