I have started brewing with Kvieck yeast at a fermentation temperature of 36 degrees celsius using a temperature controlled fridge and heat belt . I have gone through two heat belts in four brews. Is this temperature too high to be using a heat belt? Has anyone had this experience and if so what are you using to heat your brews when using Kvieck yeast? I would really appreciate some advice as I cannot keep buying heat belts at this rate.
