As I was making my coffee this morning the sun caught the bottom of my hand-grinder, which at some point last year sat in water just long enough to begin to oxidize; the sun brought out the hint of green copper. I composed this before I lost the light.

The Zassenhaus is in heavy use these days; I sold my grinder out in California but kept my espresso machine. Luckily, my schedule these days allows me ample time to grind coffee by hand and self-document.
