Hi there. I'm new ro winemaking and this is wine#2 I am working on today. I am starting a tropical dragon's blood wine based on traditional dragon's blood recipe but using different fruits and juices. I'm using a blend of orange, pineapple, and mango juices. I noticed that Danger Dave does not use campden tablets in the first 24 hours and neither did another recipe for the tropical version I found. Why not? Do I need them? I am not using any lemon juice.
