I use a Saeco Titan grinder set just a touch finer than drip. I always use the inverted method in any of my AP preparations. My procedure is very similar to
STEVE LEIGHTON'S WITH HAS BEAN with the exception of me obviously using the Coava Disk instead of paper filters and me also adding a small amount (~2 oz.) of hot water to the inverted AP chamber prior to me adding my coffee, I then add the rest of the hot water and stir the "slurry" to promote an even saturation of the coffee grounds. I also push very quickly with a very light, yet consistent pressure on the chamber and I always stop before I completely compact the coffee grounds (right before the "hiss").
I'm sipping a cup (made how I just described above) as I'm writing this and I'm thoroughly examining it to see if I can detect any fines or sludge (or to just see if I'm crazy
), but I'm still coming up negative on
both all three fronts. Sure, the cup is "oilier" compared to using paper filters and there is a "oily swirl" near the bottom of the cup, but I do not get little bits of coffee grounds floating around or any "muddy sludge" at the bottom of my cup like a French Press. No "magic tricks" here, just a really good cup of coffee....
