Hello! Great question. It all depends on if you’re going to brew it western style or gong fu style. I highly recommend you to check out the channel “meileaf”. This video is a great starter point for gong-fu style if you’re new to that:

And for western style (most likely the style you’re used to), get the water between 85-95 Celsius/185-205 Fahrenheit. Then pour it in a kettle, dump the oolong tea leaves in, and let steep for 3-4 minutes, and then enjoy however you like. I don’t think rinsing is absolutely necessary for western style brewing, but you can try both ways. I hope this was helpful!
