Boiling water (sans grinds) in a microwave can be very dangerous and should not be recommended. It is possible to superheat the water (which means to heat it to above it's boiling point without it boiling). When you then put something into it (especially something with a lot of surface area, like ground coffee) it can spontaneously boil (effectively explode) all over you.
So put the grinds in first!

That's very interesting. How does it happen, surely the pressure in the microwave is the same outside?Originally posted by MrJack View PostBoiling water (sans grinds) in a microwave can be very dangerous and should not be recommended.

Heating the water in the microwave is fine, just don't overheat it. You might consider nuking it for 45 seconds to a minute depending on cup size and the water temp at the start.Originally posted by MrJack View PostBoiling water (sans grinds) in a microwave can be very dangerous and should not be recommended.

I would only use the microwave oven to heat the water. Don't put metal or plastic coffee maker components in the oven. If I do a cold drip brew I will store it in the fridge and nuke a cupful for 1 minute.

Dead right. I had a mate got 3rd degree burns up his arm when he tried to put a spoonful of instant into a nuked cup of water. I'd been standing right next to him when the MW finished and had just moved back to the table and was looking at him when it happened - the contents in the cup literally geysered up over his arm.Originally posted by MrJack View PostBoiling water (sans grinds) in a microwave can be very dangerous and should not be recommended.
