Understanding Kombucha Fermentation
Before we dive into the shelf life of homemade kombucha, it’s essential to understand the fermentation process. Kombucha is made by adding a symbiotic culture of bacteria and yeast (SCOBY) to sweetened black tea. The SCOBY feeds on the sugars in the tea, producing a fermented drink rich in probiotics, acids, and other beneficial compounds. The fermentation process can be divided into two stages: primary fermentation and secondary fermentation.
Primary Fermentation
Primary fermentation is the initial stage of fermentation, where the SCOBY is added to the sweetened tea. This stage typically lasts between 7-14 days, depending on factors such as temperature, tea strength, and SCOBY health. During primary fermentation, the SCOBY converts the sugars in the tea into a fermented drink with a unique flavor and aroma.
Secondary Fermentation
Secondary fermentation, also known as bottle conditioning, is an optional stage where the fermented kombucha is transferred to bottles with a tight-fitting lid. This stage allows the kombucha to carbonate and develop a fizzier texture. Secondary fermentation can last anywhere from a few days to several weeks, depending on personal preference and storage conditions.
