In a previous post, I linked to a video I did on making good and affordable espresso. Now I link to a similar video on affordable mocha making.
BTW, I have relegated my ROK grinder to backup duty: the 1ZPresso is now my goto, and better yet, my coffee is always freshly ground, no matter where I am. Yup. More on that later.
Once again, this video is produced in blender.
