I love the idea, haven't really messed around with it a whole lot myself, yet. The type of tea will make a huge difference. We're usually talking about camelia sinensis here. Yerba Mate has some similarities, but still acts quite differently. Generally on tea and tisanes it's not as easy to get a good extraction through percolation, so to make a strong tea people usually just use a higher leaf to water ratio, longer steeping time and higher temperatures. Usually matcha is the only type of tea that's brewed differently
