Why is 'when in doubt, throw it out' a good rule? Understand why it's always safer to discard a questionable batch of kombucha than to risk your health.

'When in doubt, throw it out' is a good rule for kombucha brewing because it prioritizes safety and prevents the consumption of potentially harmful mold or bacteria that can contaminate the brew. It's better to be safe than sorry when dealing with fermentation.
Detailed Explanation:
Kombucha brewing involves a complex fermentation process where a symbiotic culture of bacteria and yeast (SCOBY) transforms sweetened tea into a tangy, slightly acidic beverage. While this process is generally safe, it's susceptible to contamination from unwanted microorganisms, particularly mold. Distinguishing between a healthy SCOBY and harmful mold can sometimes be challenging, especially for beginners. Mold can produce toxins that are dangerous to consume. Therefore, if you observe any unusual growth, discoloration (especially black, green, or blue), or foul odors that deviate from the typical vinegary smell, it's best to discard the entire batch. This minimizes the risk of consuming harmful substances and ensures your safety. It's also important to note that while a healthy SCOBY can have brown or stringy bits, fuzzy or brightly colored growth is a red flag.
Pro Tip:
Always use a glass jar for brewing kombucha, as plastic or metal containers can leach chemicals into the brew or react with the acidity, potentially affecting the taste and safety of your kombucha.
