Controlling the water changes the speed but you still can’t get a real immersion going for any amount of time, especially during the bloom. Not sure about an airtight lid. My idea was to buy a laboratory speed funnel that’s designed to filter liquids which is basically what the V60 is by design. Same 60-degree conical shape and inner spirals designed for maximum liquid draw down speed.
Need a manual stopcock valve that fits the 3/8" OD of that spout but I’m having trouble finding one rated food grade and with high enough temperature clearance. At first I thought it would be trivially easy to locate this but finding a single supplier who will sell me one unit of each is tricky. I don’t really want to buy a Switch just to throw the glass away and still have to rig something up.
That coffee looks dark as shit and what he’s calling fine looks medium to me at best. That final bed where the middle collapses like the foundation of a south Florida high rise is standard in Japanese brewing, as are dark roasts, coarse grinds, and low ratios. So it wouldn’t surprise me if this sucked for LRSO.
Actually. Thinking about it. You want some kind of screw valve. With a little handle on the side that can increase or decrease the flow. This would need to be below the cone.
I’m imagining something like this without the charcoal filter:
I dunno about a screw valve to control flow rate. I haven’t seen one yet that’s plastic, NSF, and rated for coffee brewing temps. If I can just get the on/of valve I’ll be happy.
yeah the marketing for this seems to be “it’s for dummies” so this tracks. it’s aimed at normies. Maybe this is how I get my wife to try pour-overs (she uses the aeropress and thinks (rightly) that the v60 is an insane torture device)
Have you pointed out that her Aeropress looks like a penis pump? That might get her to abandon it instantly. Or maybe the opposite and she finds it even more endearing, which…ok look I’m not a marriage counselor don’t take advice from me.
I did a little more research on this and people are saying that there’s no such thing as food safe 3d plastic printing, especially not this application since the glass temps of the print plastics are considerably lower than the water. The non-toxic options would be finish in a food grade epoxy or 3d print the mold and cast from a food safe material like silicone. It’s the latter one I have experience with and was considering. However, I suppose one could 3d print and check the brew parameters without consuming the coffee to check for major design flaws before moving on to the messy and tedious mold-making and casting process.
oh yeah I would never actually consume coffee that touched a 3D printed cone, I was thinking more in terms of just validating a design (does it seal etc) before trying to get a “real” prototype fabricated out of a suitable material
I took a swing and binked the timing first go—15 second pour of 300g water that drained in 90 seconds—and obv got the same sunken goatse bed they got in the video.
…it wasn’t bad! It wasn’t as good as a regular cup, the mouthfeel was different and it wasn’t as rounded, but I could see some folks being into this if it always made a comparable cup in a foolproof way
for anybody out there at the beginning of your coffee journey, goatse bed is an important technique, it’s tricky to describe but honestly you can figure it out just by google images
I finally got around to this Ethiopia Chelbesa from Tokyo. I’m having no trouble brewing it so I think it was just that other coffee. This one’s not really too bright and definitely not sour. Reminds me of the Yemen mokka both in appearance and profile.
I just got a printer and am going to be messing around with stuff like this. So far I’ve printed the Orea Negotiator which works nicely for flattening out filters for my stagg xf brewer.
Eventually I’m going to play around with prototyping brew devices as well. Probably starting by trying to clone the Orea since it’s out of stock everywhere.
I noticed recently that I’m getting too many fines for a medium grind off the Vario, so I finally checked the alignment today and sure enough it was off slightly. It’s tendency is to lean to one side (the left if facing the machine), and the problem lies in the plastic burr carrier from the old Vario design. I remember determining this by painstakingly marking the burr in every orientation the first time I did this, so my quick fix is to shim the tabs of the metal upper burr carrier itself with some aluminum tape with known thickness (25 microns). Two tiny tape shims later and I got a clean wipe and an excellent cup of this Ethiopia Chelbesa that’s balanced the way you’d expect from an aligned flat burr.
YMMV but seems like I have to do this once or twice a year, and I believe it to be seasonal. We’ve had some spring weather here recently and that’s when I started to notice it. I suspect that the metal-chambered Varios and Fortes you guys have aren’t as susceptible this but I’m not certain.
Related: Guitars often require the same sort of seasonal micro-adjustments to remain in optimal playing condition. In fact, I just finished doing a setup on a vintage piece I recently bought that shipped from the heat and humidity capital of Atlanta. That process involves using a perfectly machined straight edge to test for high frets and a set of automotive feeler gauges to adjust the neck relief, which, depending on the guitar and playing style is optimally set somewhere between about 150 and 500 microns (0.006" to 0.020"). I’m rambling but the thing you may find interesting is that there’s a modified CNC machine called PLEK that both measures and files frets onto the perfect plane with 1 micron accuracy.
True. I do think he’s leaving a lot of money on the table though. Not optimizing video length, avoiding affiliate links, etc. but I respect his desire to be and appear objective.
Based on some of his comments about his personality, I think he does a lot of it to get positive attention and that’s what he gets value from.
Unfortunately, YouTube’s algorithm shapes the decisions that many creators make which leads to a sort of sameness to their videos regardless of the topics they’re about. Anything outside of that simply doesn’t make much money.
Another issue is that there’s way more content being created than there is time to watch it.
