Just wanted to ask a few questions about the newer Mahlkonig grinders and advancements in espresso grinding technology.
1) Is anybody using either the K30 Air or PEAK grinders at their espresso bar?
2) Has there been in hard documentation on the effects cooling the grinding process and better flavor extraction?
3) Are there any other espresso grinder companies besides Mahlkonig that are producing grinders with the air cooling technology?
4) Are there any other recent advancements in grinding quality besides air cooling and burr size?
