I'm wondering if we should start a sticky post which contains everyone's collection of Bean/Grinder+Setting/Brew method information as a reference. It's always good to have a nice starting point.
Thanks for starting this. I almost exclusively brew light roasts via Chemex. I'll vary my grind slightly depending on how many cups I'm making, but for my standard two cup (32g of beans) recipe: 20 on Encore for Chemex.
When making one cup I'll use ~18, and for three cups I'll use ~22.
I'm not sure how much it matters to anyone else - might just be something that I do. I'd be interested to hear if anyone else adjusts grind based on weight of beans, though. Or maybe it's more common just to always brew the same amount with a particular method?
