Coffee

Extraction, roasting, water, and the equipment argument.

All shelves

Why this shelf

A daily ritual that turns out to be a measurement problem, where the variable deciding the outcome is usually the one nobody is adjusting.

  1. Espresso Coffee: The Science of Quality by Andrea Illy & Rinantonio Viani

    Book

    Espresso Coffee: The Science of Quality Andrea Illy & Rinantonio Viani, 2005

    The academic text the rest of this shelf is standing on — chemistry, physics, and physiology, with no interest in whether you enjoy reading it. I open it to settle a claim, never to learn a method.

  2. The Professional Barista’s Handbook by Scott Rao

    Book

    The Professional Barista’s Handbook Scott Rao, 2008

    Written for people who are paid to be consistent, which makes it unsentimental about everything the hobbyist enjoys. The pages on distribution and channelling explained a fault I had spent a year blaming on the beans.

  3. The Curious Barista’s Guide to Coffee by Tristan Stephenson

    Book

    The Curious Barista’s Guide to Coffee Tristan Stephenson, 2015

    History and hardware given the same weight as method, and honest that most of the ritual is inherited rather than reasoned. The handsomest book here, which is most of why it keeps getting lent out.

  4. Water for Coffee

    Book

    Water for Coffee Maxwell Colonna-Dashwood & Christopher H. Hendon, 2015

    One variable taken seriously enough to fill a book — and the one people ignore while fussing over five that matter less. It turned brewing from a technique into a chemistry problem I happen to drink.

  5. Craft Coffee: A Manual

    Book

    Craft Coffee: A Manual Jessica Easto, 2017

    The clearest writing on brewing outside espresso, and it says plainly which decisions change the cup and which are theatre. The one I hand to someone who has just bought a grinder.

  6. The Physics of Filter Coffee by Jonathan Gagné

    Book

    The Physics of Filter Coffee Jonathan Gagné, 2021

    Fluid dynamics and particle distribution applied to a pourover, with the modelling shown rather than asserted. Demanding, occasionally past me, and the only book here that changes what you think a grinder is for.

  7. How to Make the Best Coffee at Home by James Hoffmann

    Book

    How to Make the Best Coffee at Home James Hoffmann, 2022

    Every decision priced honestly — what it costs, what it buys, and when it stops paying. The best door in, because it settles the equipment argument early enough that you can get on with the interesting part.

    Best door in
  8. Coffee, for Here: The Ultimate Handbook for At-Home Coffee Enthusiasts

    Book

    Coffee, for Here: The Ultimate Handbook for At-Home Coffee Enthusiasts Morgan Eckroth, 2026

    Written from behind the counter rather than the lab — what a café learns about serving people, translated to a kitchen. A fair correction to a shelf that otherwise treats coffee as a physics problem.
