The Espresso Guide

The Espresso Guide

Concentrated and alive with character, espresso is where origin flavors show up at their most vivid. A well-pulled shot is a window into the bean: its terroir, its processing, its story. Take your time with the dial-in and the cup will reward you.

What You'll Need

  • Espresso machine
  • Portafilter and basket
  • Burr grinder
  • Kitchen scale (0.1g accuracy)
  • Tamper
  • Shot glass or small pitcher
  • Timer

Recipe

  • Dose (in): 18g
  • Yield (out): 36g
  • Water temperature: 90 to 94°C
  • Grind size: Fine
  • Total brew time: 25 to 30 sec
  • Ratio: 1:2

Steps

1

Heat your espresso machine fully before brewing. Flush the group head with hot water to stabilize the temperature.

2

Grind 18g of coffee into the portafilter basket. The grind should feel like fine table salt between your fingers.

3

Level the grounds evenly using your finger or a distribution tool, then tamp straight down with firm, even pressure.

4

Lock the portafilter into the group head and place your shot glass on the scale. Zero the scale.

5

Start the shot and the timer simultaneously. A well-extracted shot flows like warm honey: golden, steady, and unhurried.

6

Stop at 36g yield or around 28 seconds. Adjust grind finer if it runs too fast, coarser if it runs too slow.

7

Taste. Then dial in. A good espresso takes a few attempts and that is entirely normal.

Tips

✦︎

Medium to medium-dark roasts work best for espresso. Beans from Colombia or Brazil, with notes like Dark Chocolate, Caramel, and Hazelnut, pull consistently well and forgive a slightly off dial-in.

✦︎

Sour shot means under-extraction. Go finer or add a second to your brew time. Harsh and dry means over-extraction. Go coarser.

✦︎

Rositas Reserve microlots shine brightest as espresso. The intensity of the brew method amplifies the terroir, and those complex tasting notes have nowhere to hide.
