Ecuador naturl typica and sidra may not be a good model, grown at 1450 MASL compared to Yemeni at 2200, but here's first effort with a Yemeni coffee 150 g. Cupping and tasting I am sure to enjoy. {image}

I find it a tad bit more messy than the Niche but very similar than the Atom 60 I have. With RDT it cuts down the mess but once and a while you'll get grinds and chaff all over

I would keep more coffee from ethiopia around, but ... same issue

I would try changing out the pressurestat to a Sirai model. If the unit is older the original part could be failing as this directly impact water temperature. Elektro's has a video on installing the pressurestat

One my, wife hates it, favorites, a good Yemen. Been sipping that the last few days

@baldheadracing suggests that the grinder has some reasonable burrs in it. It sounds like the steps are your greatest frustration. If so, you might look to see if someone has modified it to remove the stepped adjustment. If so, that might get you going without buying another grinder

My friend could smell but his taste was off, some foods tasted ok but said coffee tasted like dirt for a few weeks

While I am getting prepared to roast 150 g Boldjava sent me, I thought I would post some graphs of some tasty small charge roasts from the Huky Alliance for Coffee Excellence is generous with samples of green coffee relative to some other auctions. 200 grams from the One of a Kind Guatemala auction: {image} But

I thought there was a vent hole in the rim of the Kalita Wave to prevent that type of thing. The vent hole would need to be inside of the cup or carafe rim. But I don't own a Kalita
