So I'm trying to use the THP method. Is tap water that has been filtered through a purifier and pre-boiled okay to use? I have read that it is both okay and not okay to use, that contaminants int he water may destroy alkaloids. Possibly even fluoride contamination could ruin the brew? I do not wish my first brew to be a failure.
Also for Chakruna would the same ratio for B. Caapi be the same 1g for 150ml of water?
