My wife loved the California Trinity Red so much that I ordered two more kits and another primary. I'm making them both at once. Do I need to sanitize the spoon, hoses, hydrometer, etc between each batch while working on them or can I just go from one to the other? I know the little voice in my head says to lower the chance of cross contamination in the minute chance that would happen that I should sterilize each time I switch. Just looking for feedback I suppose.
