We certainly are not supporters of this party. Yes, it can indeed heat your Chemex coffee in no time. So, if you crave a quick caffeine fix and won’t bother much about the authentic flavor of Chemex coffee then you can go this way, but not all the time.

In general, microwaves break down the rich aroma of coffee and end up with an OK sort of coffee, not the enjoyable one. Lastly, if caffeine is what you care about the most, then be that your caffeine is not going anywhere because of microwaving.
