Either way. It depends on how thirsty I am for that particular tea. If I don't want more until much later, however, I make sure there's enough air circulation to let the leaves dry if left long enough. IOW, I don't let them sit in even the smallest amount of water for hours at a time at room temperature because bacteria may grow. I'm partial to brew baskets for this reason. For my Fuguang tea traveler, I merely turn it upside down and let it rest on the dish drainer rack.
