  • 140F or 60C Temperature Rate: By this temperature, the garlic will need several weeks of fermentation for the best quality. However, if you ferment the raw garlic at this temperature, the colour of black garlic is not beautiful at all. About the taste, the black garlic produced at 60C is sweeter but the amount of vitamin and antioxidant is a little lower.
  • 158F or 70C Temperature Rate: If you ferment the garlic at this temperature, it takes just more than a week for the best result. The colour is beautiful and the nutrients increase significantly. We highly recommend producing the black garlic at this temperature.
  • 158F or 70C Temperature Rate: The higher the temperature environment it is, the quicker the fermentation process happens. Therefore, if you produce the black garlic at this temperature, it just takes less than a week. But, at this temperature rate, it is hard to control the process for the best taste and the black garlic flavour can be a bit bitter.
