Kefir quality is a ected by di erent fermentation parameters, such as type of kefir culture, inoculation ratio, time, and temperature [1].

Starting from pH = 3.5, 4.5, and 6.0 in presence of sucrose, pH decreased in the first 24 hours due to the well-known fermentation process. WebbThe culture produces some gas as it grows in the yogurt, and if there is no place for that gas to go you will have a pressure buildup and potentially an explosion. 22 hours is quite a while to build up gas, maybe try a shorter fermentation or leave a little give in the jars for gas to escape. There’s also the small possibility that your ... bioswing haider
