Ever hear of Kombucha tea ? https://en.m.wikipedia.org/wiki/Kombucha I'm on my 6th batch and make this every so often. Mostly use organic black tea but sometimes add some Darjeeling or Jasmine. Have also experimented with Rooibos and adding some Yerba Mate. Post brew I add different fruits and sometime herbs/spices. Here is my latest batch black tea\Rooibos post brew in glass containers with the addition of mulling spices and chunks of mango and peach. The Rooibos addition makes for a milder less acidic flavoured result. Previous batch I added strawberries, blueberries and backyard mint which made for a red coloured tea that tasted a lot like cranberry juice concentrate.
