Step-by-Step Barista Guide

The La Marzocco Linea Mini brings commercial-level espresso performance into a compact, beautifully designed machine. While it’s intuitive to use, getting the best results still comes down to good barista fundamentals: preparation, consistency, and workflow.

In this guide, we walk through how to use the Linea Mini step by step, from warm-up to pulling shots and steaming milk, so you can brew confidently and consistently.

Getting Started: Warm-Up & Prep

Before making coffee, ensure the machine is fully ready.

  • Turn the machine on and allow at least 20–30 minutes to fully heat

  • Ensure the portafilter is locked into the group head during warm-up

  • Check the water reservoir is filled (if not plumbed in)

A fully warmed machine is essential for temperature stability and consistent extraction.

Step 1: Prepare Your Coffee

Good espresso starts with good preparation.

  • Grind fresh coffee at the correct espresso grind size

  • Dose consistently (e.g. 18g, depending on your basket)

  • Distribute grounds evenly

  • Tamp firmly and level

Consistency here makes everything else easier.

Step 2: Pulling an Espresso Shot

  1. Lock the portafilter into the group head

  2. Place your cup or scales under the spouts

  3. Lift the brew paddle to start extraction

  4. Lower the paddle to stop the shot at your target yield

A typical recipe might be:

  • 18g in / 36g out in 25–30 seconds

Use time, yield, and taste to guide adjustments.

Step 3: Adjusting Extraction

If your shot runs too fast or too slow:

  • Adjust the grinder, not the machine

  • Finer grind = slower flow

  • Coarser grind = faster flow

Make small changes and pull another shot to evaluate.

Step 4: Steaming Milk

The Linea Mini is capable of excellent milk texture when used correctly.

  1. Purge the steam wand before use

  2. Position the wand just below the milk surface

  3. Introduce air briefly, then texture

  4. Heat milk to around 60–65°C

  5. Purge and wipe the steam wand immediately after use

Clean steam wands = better milk and better hygiene.

Step 5: After Each Coffee Session

Good habits keep the machine performing well:

  • Flush the group head

  • Wipe and purge the steam wand

  • Rinse portafilter and basket

  • Wipe down surfaces

These small steps prevent buildup and make end-of-day cleaning easier.

Common Mistakes to Avoid

  • Brewing before the machine is fully heated

  • Changing grind and dose at the same time

  • Forgetting to purge the steam wand

  • Ignoring grinder cleanliness

Most espresso issues come from workflow, not equipment.

Build Consistency Over Time

The Linea Mini rewards:

  • Consistent dosing

  • Small grinder adjustments

  • Regular cleaning

  • Attention to taste

Once you understand the basics, it becomes a joy to use.
