I'm very new to sifting, and that was my very first time sifting for the metal filter. I think you're right that I'm better off with an immersion method if I'm sifting and using metal. I could do the ol' inverted AeroPress+metal instead. I think you're right on about it being underextracted because of the too-fast flow.
Although, I'll say, before I ever messed around with sifting, I got some great cups with the metal cone, and a medium-fine grind. More body than a V60 of course, but probably sacrificing some clarity? Not sure... amateur speaking here. :)
I've been using the Coava cone off and on for a few years and I like it. Lately I've moved back to paper for the most part, as I'm trying to learn "the right way" to do a V60. But this morning I did a metal cone actually.... and it didn't work out well. It was kind of an experiment to see what'd happen if I pre-sifted out the fines (I have a 500 micron sieve). Alas, this led to an extremely fast drawdown. I knew that fines slowed drawdown in paper, but people don't talk about metal out here very much, hence the experiment.
I've been back on a roasting kick, using a popcorn popper. It works surprisingly well, it's cheap, and another fun thing to nerd out to! This week I'm brewing a few different roasts (all in the light-to-medium range) of an Ethiopia Sidamo bean from Sweet Maria's (my main source for green beans). I usually do V60, but sometimes Kalita, lately using Lance Hedrick's 1-2-1 recipe. I have a LIDO 2 hand grinder that I'm pretty happy with. I'm toying with the idea of sifting out fines, but I'm not sure I want to throw that big of a variable into my process just yet--differences between roasts and slight changes I make to pouring etc. are enough variables so far.
And yes, very satisfied! This 1-2-1 recipe has allowed me to grind coarser than usual (I think because of how you agitate the fines out of the bed and into the filter, which slows the drawdown), and that has really helped with flavors. (Another reason I'm not sure I want to sift out fines just yet.)
or a naturopath (just throwing it out there... I find specialist MDs to be very narrowly focused and often don't look outside their box to find solutions)
Interesting, I just finished this book. I tried it in high school, it seemed profound at the time, but I couldn't finish it. Now I'm an older software dev and it was much easier to read this time around, but I feel like I missed something. Did Hofstatder gloss a bunch of stuff in the final couple of chapters? Or did I just fail to grasp all the strange loop stuff and put it together on my own? Not sure. I still enjoyed it, and it gave me some good ways of conceptualizing brains, minds, thoughts, etc. Especially the ant colony stuff.
We're talking about Kvaesitso, right? I see 1.29.1 from Feb 21, whether I check it on fdroid or github.
