the first time i tried the japanese iced coffee method, i ended up with a cup of coffee that had such a strong bitter, chemical taste that i was sure i must have been drinking poison. i later realized it was probably my ice cubes, which came out of those Tovolo king cube molds. after a few months, those molds impart an extremely strong chemical flavor into their ice cubes.

so… long story short, the ice you use matters a lot
