Stones In Coffee: An Ill-Advised Investigation
James Hoffmann
@jameshoffmannAbout
Hi! My name is James, and I make videos about anything and everything to do with coffee, occasionally food and sometimes business/entrepreneurship. I create how-tos, guides, reviews, vlogs, video essays and mini-documentary films. In the real world, I've started a few companies, I wrote "The World Atlas of Coffee" and "How To Make The Best Coffee At Home". I do a little advisory work for startups too. If you want to get in touch, drop me a line but please read these two things first: 1. I don't do paid reviews. I have a Patreon that helps me buy the products I want to review to prevent bias (then I give them away!) 2. I get a lot of email, so sadly I can't help with queries about which equipment you should buy.

Note: All stones used in the testing came from the destoning of raw coffee - so are good indicators of the kinds of stones you might find in a bag of roasted coffee. What happens if a small stone makes its way into your bag of coffee and your grinder? An irreversible calamity or an imperceptible event?
