Linea Mini

Introduction

For coffee enthusiasts and home baristas, the quest for the perfect espresso can be a lifelong journey. Enter the La Marzocco Linea Mini R, a compact powerhouse that brings commercial-grade espresso capabilities to your kitchen countertop. This updated version of the iconic Linea Mini promises to deliver cafe-quality shots and silky microfoam in the comfort of your own home. But with a price tag that might make your wallet wince, is it worth the investment?

Brief history of La Marzocco

Founded in 1927 as Officine Fratelli Bambi, La Marzocco was established by brothers Giuseppe and Bruno Bambi to create their own line of coffee machines. Their first machine, the Fiorenza, was designed for Mr. Galletti, who later stepped away from espresso machine design. 

Over the years, La Marzocco became known for its industry-changing innovations. In 2015, the company introduced the Linea Mini, a home espresso machine inspired by the iconic Linea Classic. Featuring a dual boiler, pre-programmed pre-infusion, and a built-in water reservoir, the Linea Mini brought professional-quality espresso making to home users. 

More recently, La Marzocco launched the Linea Mini R, an updated version with a modern design, a front-facing shot timer, and a self-cleaning gicleur valve (the gicleur, also known as the flow restrictor, is a tiny cylindrical piece of metal with a small orifice through it) that reduces the maximum flow rate by 25% compared to the original. The Mini R also includes a two-in-one bottomless portafilter with a splitter extension, whereas the original Mini came with standard La Marzocco portafilters. Additionally, it features a second solenoid instead of just one, allowing for an extra 'bloom' phase in the brewing process, providing more control over extraction.

Design and Build Quality

La Marzocco has a reputation for building tanks disguised as espresso machines, and the Linea Mini R is no exception. The machine's exterior showcases the new "Della Pietra Curve," a design element inspired by the La Marzocco Linea Classic S and shared with the La Marzocco Linea Micra. This subtle slant along the side panels gives the Mini R a more modern and streamlined appearance compared to its boxy predecessor.

The build quality is nothing short of exceptional. La Marzocco uses commercial-grade components throughout, ensuring longevity and consistent performance. The stainless steel body not only looks sleek but also resists corrosion and is easy to clean. The drip tray feels solid and now has a float indicator to prevent overflows.

One notable design change is the backplate, which now matches the colour of the side panels instead of being polished stainless steel. This unified look is not only aesthetically pleasing but also easier to maintain.

The Linea Mini R is available in a classic stainless steel finish, as well as a range of colours to match your kitchen decor. While it's not a small machine by any means, its footprint is relatively compact considering its capabilities, measuring just 35.5 cm in width.

Core Functionality

Espresso Extraction

At the heart of the Linea Mini R is its ability to produce exceptional espresso. The machine uses a 58mm integrated brew group, the same size found in commercial La Marzocco machines. This, combined with the PID-controlled brew boiler, ensures temperature stability throughout the extraction process.

The brew paddle, while not a true flow control device, provides a satisfying manual interface for starting and stopping the shot. La Marzocco has introduced a new pre-infusion system in the Mini R, which uses a dual solenoid to create a three-stage extraction process:

1. Pre-wet: Initial water contact to expand the coffee grounds
2. Pause: A brief halt in water flow while maintaining basket pressure
3. Full pressure: The main extraction at 9 bars of pressure

This pre-infusion system aims to reduce channelling and improve overall shot quality, especially with lighter roasts or slightly uneven tamping.

‍Temperature Stability

‍Temperature stability is crucial for consistent espresso, and the Linea Mini R excels in this area. The PID-controlled brew boiler maintains a steady temperature, which can be adjusted either through the temperature wheel on the side of the machine or via the La Marzocco Home app. The last change always overrides the previous one, ensuring the most recent setting takes effect. 

The integrated brew group acts as a massive heat sink, significantly contributing to temperature stability. This design, borrowed from La Marzocco's commercial machines, ensures that the brewing temperature remains consistent from the first shot to the last. 

The Linea Mini also incorporates a Thermal Stability System that further enhances its temperature management. When water enters the machine, it splits into two paths: one goes to the steam boiler, where it is heated to generate steam, and the other heads towards the coffee boiler. Before reaching the coffee boiler, the water passes through a pre-heater inside the steam boiler, ensuring better thermal stability. The water exits the steam boiler at a very high temperature, where it is mixed with cold water in a mixing valve to reach the ideal temperature before entering the brew boiler. The brew boiler itself is made from a substantial mass of stainless steel, maintained at the perfect temperature by two heating cartridges. Once the brew paddle is engaged, water is pushed by the pump through a brew valve and flows through a spiral water path, positioned between the two cartridges, ensuring it reaches the precise brewing temperature. Finally, a temperature probe, located just a few millimeters from the shower screen, provides an accurate reading to verify the water temperature, ensuring optimal brewing conditions. 

‍Steam Performance

‍The Linea Mini R's steam capabilities are nothing short of impressive. With a 3-litre steam boiler and a four-hole steam tip, this machine can produce café-quality microfoam in seconds. The steam power is so robust that it can texture milk for a single flat white in under 10 seconds.

The new cool-touch steam wand is a welcome addition, reducing the risk of burns and making cleanup easier. La Marzocco has also included a stainless steel steam tip for those who prefer a more traditional feel.

‍Water Delivery

‍The hot water spout, while not a primary feature for many users, dispenses water directly from the steam boiler, making it extremely hot – perhaps too hot for immediate consumption in an Americano. Users may need to add cold water or wait for the drink to cool before enjoying it. However, the spout is also a great tool for cleaning your portafilter, offering additional functionality for maintaining the machine.

User Experience

Learning Curve

The Linea Mini R strikes a balance between simplicity and depth. For basic operation, the machine is relatively straightforward – fill the water tank, turn it on, wait for it to heat up, and you're ready to brew. However, mastering the nuances of extraction and milk texturing will take time and practice.

The brew paddle, while intuitive, doesn't offer the same level of control as some competitors with flow profiling capabilities. However, this simplicity can be an advantage for those who want to focus on the fundamentals of espresso making without being overwhelmed by too many variables.

Daily Operation

In day-to-day use, the Linea Mini R shines. It's ready to brew in about 10 minutes, with full steaming capacity available in about 15 minutes, thanks to its efficient flash boiler system. The removable drip tray and water reservoir make cleaning and refilling simple, although accessing the water tank requires removing the drip tray first. Having the drip tray positioned away from the heat is also a plus, as it helps prevent water from evaporating too quickly and becoming denser in minerals, making it easier to manage and clean. 

The barista lights illuminate the brewing area when the group is engaged, providing better visibility for shot assessment. The new rinse mode, activated by quickly toggling the brew paddle, offers a convenient way to clean the group between shots.

Adjustability and Customisation

While not as adjustable as some prosumer machines, the Linea Mini R offers several ways to tweak your espresso:

1. Brew temperature can be adjusted via the side wheel or app
2. Pre-infusion time can be programmed through the app
3. Pump pressure can be easily adjusted (you can find the screw on top of the machine  
4. Steam boiler pressure can be set to three different levels via the app, allowing users to fine-tune performance to their preference. Additionally, the Linea Mini R can connect to the ACAIA Brew-by-Weight scale via Bluetooth, enabling precise shot control. Through the app, users can set two virtual yield buttons, allowing the machine to automatically stop the shot once the desired yield is reached. This functionality ensures a consistent output, similar to a professional coffee shop, making it easier to achieve repeatable results.

These adjustments allow users to dial in their shots for different coffee beans and roast levels.

Maintenance and Longevity

La Marzocco has a well-earned reputation for building machines that last. The Linea Mini R uses many of the same components as its commercial counterparts, suggesting a potential lifespan of 10+ years with proper care. In fact, La Marzocco is committed to supporting existing customers by offering retrofit kits when new hardware features are introduced. 

Regular maintenance is straightforward:

• Backflushing the group head (a blind basket is included)
• Cleaning the steam wand after each use
• Descaling as needed (frequency depends on water hardness)
• Replacing the group gasket and shower screen periodically

La Marzocco provides excellent documentation and support, including detailed cleaning instructions in the app. Spare parts are readily available, and there's a network of certified technicians for more complex servicing needs.

Performance in Various Scenarios

Single Shots vs Double Shots

The Linea Mini R comes with a range of baskets (7g, 14g, 17g, and 21g), allowing flexibility in dose sizes. It performs consistently across these different doses, though most users will likely stick to doubles in the 17-21g range.

Light vs Dark Roasts

Thanks to its temperature stability and pre-infusion capabilities, the Linea Mini R can handle a wide range of roast levels. Light roasts benefit from the higher brewing temperatures and pre-infusion, while dark roasts can be brewed at lower temperatures to avoid over-extraction.

Milk-Based Drinks

This is where the Linea Mini R truly excels. The powerful steam wand can texture milk to café-quality standards in seconds. The four-hole tip creates a vortex that incorporates air smoothly, resulting in silky microfoam perfect for latte art.

Comparative Analysis

When considering the Linea Mini R, it's important to look at how it stacks up against other high-end home espresso machines:

1. Rocket R58 Cinquantotto: Offers similar dual-boiler performance and build quality at a lower price point, but lacks the brand cachet and some of the refinements of the Linea Mini R.
2. Lelit Bianca: Provides flow profiling capabilities out of the box at a more affordable price, but doesn't match the Linea Mini R's steam power or build quality.
3. La Marzocco GS3: La Marzocco's higher-end home machine offers more advanced features like a saturated group head for superior thermal stability. It comes in two models: the AV (Auto-Volumetric), which allows users to set the number of pulses for a consistent dose, and the MP (Manual Paddle), which gives full control over flow and pressure throughout the extraction. While it lacks built-in scales, the GS3 provides a high level of precision and flexibility, making it a strong option for those looking for more advanced espresso-making capabilities. However, this comes at a significantly higher price compared to the Linea Mini R. 
4. Decent DE1PRO: Offers unparalleled customisation and data analysis capabilities but lacks the traditional look and feel of the Linea Mini R.

The Linea Mini R stands out for its combination of commercial-grade components, intuitive interface, and iconic design.

Potential Limitations

While the Linea Mini R is an exceptional machine, it's not without its drawbacks:

1. Price: The Linea Mini R is a significant investment that may be difficult to justify for casual users.
2. Size and Weight: Weighing 30kg and measuring 35.5cm wide, the Linea Mini R requires dedicated counter space and may be challenging to move. However, its size and weight are intentional, designed to provide greater performance, stability, and thermal consistency. The larger boiler and reservoir allow it to handle multiple coffees back-to-back without performance drops, making it well-suited for those who frequently entertain or brew multiple drinks. While its robust build contributes to its reliability, users with limited counter space or those who need a more portable setup may find its footprint a potential limitation.
3. Limited Flow Control: Unlike some competitors, the Linea Mini R does not offer true flow profiling out of the box. However, it is designed to deliver high-quality espresso with minimal adjustments, mirroring commercial machines used by professional baristas. While pre-infusion and pump pressure adjustments provide some level of control, those looking for full manual flow profiling may find this a limitation. That said, many roasters develop their coffee to be brewed on standard commercial machines, meaning excellent results can still be achieved without additional profiling. Users who require precise flow adjustments for experimental brewing techniques may need to look at alternative options. 
4. Learning Curve: Despite its intuitive design, the Linea Mini R still requires practice to achieve consistently great results. Users transitioning from entry-level machines may need time to adjust to its workflow and dial in their shots effectively. While the skills learned on the Mini are transferable to commercial setups, those new to high-performance espresso machines should be prepared for a learning period before mastering their extractions.
