After posting about these in the 'Evo Solo' thread Willbur started I'm realizing they deserve a discussion of their own. Here's the link again: http://www.walkuere.de/karlsbader.html?&L=3
. The brew I tried was sans paper, just straight through the porcelain filter. Full body, low sediment. I'm going to go ahead and say that Wille at Heart had me overly caffeinated at this point so I wouldn't trust my sensory perceptions 100%, but I'm excited to go back and try again soon. The filter looks like just two layers of openings in opposite directions and, again, brewed cleaner than I was expecting. I think the grind was V60ish.
