On this summer day I decided to use all the sunshine and make herbal sun-tea. I used Rooibos tea which is from the African Red Bush tree. No caffeine and full of antioxidants.
When I brought the brewed jar inside all amber and hot I stuck my instant-read thermometer in it. Yikes, it measured 130*. I then did a google search for the recommended temperature for a hot water tank. Are you ready...not to exceed 125*.
