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.

(If you're worried then I'd err on the side of slightly finer than slightly coarser) - 1L water suitable for filter coffee, room temperature - 10 drops of fining agent - optional (we chose the Mangrove Jack’s Liquid Beer Finings - other finings agents do work, use the recommended dose from the package) - Stir to make sure everything is completely mixed. You can be heavy handed with your stirring here. - Put a lid on your container and leave for 12 hours in the fridge, for the grounds to settle. - Gently pour off the liquid into a carafe. Take care to stop pouring when close to the coffee sediment A link to the fining agent we used: https://mangrovejacks.com/products/liquid-beer-finings https://mangrovejacks.com/pages/stockists Our new pour over setup still life print from TensHundredsThousands: https://geni.us/THT-Still-Life My French Press Recipe from 2016: https://youtu.be/st571DYYTR8 How To Brew Iced Filter Coffee: https://youtu.be/PApBycDrPo0 Easy Iced Coffee - Immersion: https://youtu.be/8uGGeV8A-BM My Books: How to Make The Best Coffee At Home*: https://geni.us/howtomakethebestcoffee The World Atlas of Coffee*: https://geni.us/worldatlasofcoffee The World Atlas of Coffee Audiobook*: https://bit.ly/worldatlasofcoffeeaudio The Best of Jimseven*: https://geni.us/bestofjimseven Take your films to the next level with music from Musicbed.
