Learn home espresso

Home espresso has an unusually high jargon-to-substance ratio. Pre-infusion, microfoam, channeling, single dosing, WDT, puck screens, ratios — most of it describes something simple, and almost all of it is explained by people who forgot what it was like not to know.

These guides start from zero. Every term gets defined in the sentence it appears in. Nothing here assumes you own anything in particular, and nothing here suggests a floor you have to spend to before you are allowed to make coffee.

Start here, in this order

1. **What espresso actually is** — the definition, and how it differs from every other way of making coffee.
2. **Your first shot** — a step-by-step you can follow with a machine you unboxed an hour ago.
3. **Espresso ratios** — what 1:2 means and why every recipe is written that way.
4. **Dialing in** — the method for turning an acceptable shot into a good one.

Technique, once the basics work

• **Tamping** — how hard, how level, and why level matters more.
• **Puck prep** — the two minutes before the shot that decide most of it.
• **Pre-infusion** — what it is, and whether you need a machine that does it.

Context and vocabulary

• **Espresso drinks explained** — latte, cappuccino, flat white, cortado, americano, and what actually differs.
• **The jargon glossary** — every term on this site, defined in one line.
• **How long it takes to learn** — an honest timeline, and what makes it longer.

The two sentences that carry most of it

And the second: if changing your grind does not change how fast the shot runs, stop adjusting technique. That is a grinder limit, and it is the one thing on this site that practice does not fix. See grinders.

What these guides deliberately do not do

• **Tell you there is a minimum you must spend.** The honest floor is lower than this category usually claims, and we show the arithmetic on what it costs.
• **Claim we tested anything.** We have not handled this equipment. What we publish instead is manufacturer documentation, cited, and arithmetic you can redo — see how we pick.
• **Use a term without defining it.** If we do, that is a mistake and we would like to hear about it.
