User Manual OXO 8710200 Conical Burr Coffee Grinder with Integrated Scale

You can walk away. A couple of times it needed stirring because the beans were at a low level.

We've been grinding dark coffee set for pour over for a week and have seen only the tiniest amount of static. Not sure what an espresso grind would elicit however...

It would work but it would might be difficult to get clean enough so there is no aftertaste if you use it again for coffee or even other spices.

Commonly, cold brew style brewing produces the best flavor with a coarser grind. That being said, the specific grind will depend on the variety of coffee, the method roasting - and most importantly your own tastes.

Yes on the lowest settings it grinds for espresso! I find it to be very accurate.

No, not if you have the scoop that came with your Oxo Brain Coffee Maker. But with the scale you can skip using the scoop...just dump on in and brew
