Recipe summary
60g of coffee for 1l of water That is 15g of coffee for 250ml Grind size a little finer than what you think especially for lighter roasts
Preheating is quite important. Plastic works better for heat retention However comment under suggested some advices for ceramic and glass which doesn’t involve too much water, like putting the V60 over the kettle while heating up, or even better put the V60 with the rinsed paper filter in the microwave for about 20s

Water that’s boiling is 100 degrees C, as long as you’re reasonably close to sea level. Boiling it longer doesn’t make it hotter. If you want super critical water, you need to microwave it in a very smooth container. Please be warned that this is incredibly dangerous as s.c. water can cause horrific burns as it will boil and overflow when you try to pour it. It also doesn’t make good coffee, it over extracts.
Speaking from experience? Have you actually managed to brew V60 cups with superheated water? I need to watch this youtube video.

yeah, this happens for me when microwaving water in clean glass container. not pleasant, it goes off like a bomb in there. have mitigated it by putting a wood stick in the water, but later learned to just measure the water carefully and run the microwave only as long as needed.
