I had never really thought about using an immersion brewer as a pure pour-over device but just had a mind blowing honey process Ethiopian, and I noticed barista was brewing it in a Hario switch with the switch open the whole time. Tasted as good as a v60 brew to me. I’ve been wanting to try immersion brewing for a while. I get the sense this forum and many others lean more strongly towards the clever dripper. I imagine that device could also be kept open and used as a pour-over. Do you think an open Hario switch basically IS a v60? That sounds like the ultimate multi-Tasker to me. Am I missing something here? Any thoughts on the perceived lean toward clever? I’ve ruled out the plastic version and would be looking at glass clever vs switch.
In a recent video Lance Hendricks showed that the filter paper touching the side of the brewer is what draws water out of the brewing process to bypass going directly through the bed. So the immersion of an Aeropress is not using this mechanism at all since the entire water is being pushed through the bed of coffee and immersed whereas a hario switch some of the water is still bypassing the bed directly.
How much this matters is less the shorter the period of time before the water is pulled around and outside. But it also means there isn’t really just one immersion or v60 like brewer because it depends on so many factors to determine bypass and extraction. The angle of the brewer, the contact of the paper, the technique in agitation it all impacts how gets extracted. Still as a basic idea these v60 like devices that can be closed do provide almost the same thing up to the point when you open them up at which point they will behave like a v60 and there isn’t anything you can do about that. How much that matters is hard to really know they taste pretty similar to me but Lance’s video is worth a watch because it does at least show there is a difference and that will have some impact.
