About

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. TO GET IN TOUCH PLEASE REACH OUT VIA WEBSITE: https://www.jameshoffmann.co.uk/contact-me Management: Ziggurat XYZ

Video Description

This is a good question I get asked a lot. If coffee works this way on you then you're probably curious why. We thought it deserved a special answer... If you enjoyed this, do please share it with someone! *Credits* Writer & Director: James Hoffmann Voice of Beanie: Ed Gamble Creative Direction & Animation: Andreas Niklas at Ayohkay Sound Design: Ben Sims Editor: Soufieh Producer: Shelley Hurley Pre-production: Daisy Collarile DOP: Michael Losada Production Assistant: Melinda Barbi Researcher: Sarka Stepanikova Animation Development Consultant: Tamsin Clay Bee *Research References* Gallego-Barceló, P., Benítez-Álvarez, D., Bagues, A., Silván-Ros, B., Montalbán-Rodríguez, A., López-Gómez, L., Vera, G., del Castillo, M.
