That's a good question. Been a while since I've gone actually immersion brewed with it (usually just pour over and use the stopper for pre heating with less water). I'll make a couple of cups and get back to you.
Edit:
Cup making done! The immersion brew is super clean and easy. I do think some type of lid would help for longer brew times to keep the heat in on the Switch though.
I think both the Aeropress and Switch Immersion lend themselves well to darker (chocolatier/nuttier) extractions. After this little test I will probably switch over to immersion brewing for my afternoon decaf for the foreseeable future!
I don't drink coffee, but the owner of a coffee plantation on the side of a volcano in Panama told me that it was one of the best ways to make coffee. I figure he would know.
My wife, who does love coffee, doesn't use it simply because it only makes one small cup of coffee at a time, and she likes to start the day with a big cup. She acknowledges that the taste is superior.
They're good, but I'd avoid AeroPress Clear for now, as there are crack reports on the internet. Other models are durable. Compared to French press, AeroPress produces cleaner cups because of paper filter utilization. Also, though AeroPress is an immersion brewer, it also allows percolation.
