Did you know that the vegetables in your refrigerator are fermenting right now? However, since they are exposed to air, the bad bacteria that causes mold and slime is more prevalent than the good bacteria that turns fermented veggies into a nutrient-rich probiotic.
Fermentools helps you control the environment and promote the good bacteria, while discouraging the bad bacteria from becoming dominant. The solution to this is eliminating all (or most) of the oxygen from your ferment, stopping the growth of the other strains of bacteria. You see, as the good bacteria starts to grow, it gives off lactic acid and carbon dioxide. The carbon dioxide is heavier than air, so it sinks to the bottom, keeping the oxygen away from your food. With an air lock, you can vent these gasses, leaving a perfect environment for your ferment.
