Handcraft Supplies Heat Belt
The Handcraft Supplies Heat Belt can be used to maintain your fermentation temperature by applying a gentle heat to the outside of your fermentation vessel.
The Heat Belt will help you avoid cool fermentation temperatures, which reduce your yeast's performance and increase the fermentation time.
Simply tighten the belt around your fermenter and adjust the heat belt's position to adjust the temperature. Positioning the belt lower on the fermenter will increase the temperature and positioning it higher will decrease the temperature.
