Öztiryakiler Mini Barista Grinder Espresso Coffee Machine, Single Group

Öztiryakiler Mini Barista Espresso Coffee Machine, with Grinder, Single Group

Öztiryakiler Mini Barista is a household espresso machine that brings the entire espresso preparation process, from bean to cup, together in a single appliance with its built-in steel conical burr grinder and dual boiler design. Thanks to its 250-gram removable bean hopper and 15-step grind adjustment, coffee is ground to the desired fineness just before brewing. Up to 22 grams of coffee can be brewed with the 58 mm portafilter.

The 1500 W coffee boiler and 1300 W steam boiler operate independently, and the dual heating system with PID and NTC temperature technology actively controls the brewing temperature. In the dual pump system, 20 bar of pressure is dedicated to coffee brewing and 5 bar to the heating and steam system. With the milk frothing wand, hot water outlet and cup warming function, espresso-based beverages are prepared from a single machine. With its stainless steel body, touch control panel and 2.7-liter removable water tank, it offers a barista experience at home.

Get to Know the Mini Barista

You can watch all the features of the Mini Barista, from its grinder to its steam wand and from its control panel to espresso preparation, in Mutbex's detailed review video. In the video, the machine is introduced hands-on together with a professional barista.

Since the grinder, boilers and milk frothing system are combined in a single body, there is no need for a separate coffee grinder. This design saves space on the kitchen counter while allowing beans to be freshly ground for every cup. The machine can also be examined in person at the Beyoğlu Store before purchase.

What Is a Dual Boiler Espresso Machine?

A dual boiler espresso machine has two separate boilers for brewing coffee and producing steam. While single boiler machines require the boiler temperature to be changed between brewing and milk frothing, in a dual boiler design each process runs in its own boiler at its own temperature.

In the Mini Barista, the coffee boiler keeps the brewing temperature stable while the steam boiler stays ready for milk frothing. This design shortens the waiting time when preparing milk-based drinks such as lattes and cappuccinos and ensures that espresso quality is not affected during milk frothing.

How to Make Espresso with the Mini Barista?

For a good espresso, instead of relying on a single fixed setting, the grind size, coffee dose, temperature and brewing time need to be adjusted with small changes according to the coffee beans used. In the Mutbex video, these settings are demonstrated step by step on the Mini Barista.

• Fill the bean hopper with freshly roasted espresso beans.
• Select the grind setting and grind the coffee into the portafilter.
• Tamp the coffee with even pressure to create a level surface.
• Attach the portafilter to the group head, start brewing and monitor the pressure gauge.

The machine's pump has a capacity of 20 bar, but the target pressure for espresso extraction is approximately 9 bar. If the coffee flows too fast, the grind is made finer, and if it flows too slowly, it is made coarser. For detailed information on grind settings, you can read our article How to Adjust a Coffee Grinder.

Result in the Cup	Possible Cause	Recommended Adjustment
Coffee flows too fast and tastes sour	Grind too coarse or dose too low	Make the grind finer or increase the dose
Coffee flows too slowly and tastes bitter	Grind too fine or coffee tamped too hard	Make the grind coarser and balance the tamping pressure
Thin, light-colored crema	Stale beans or grind too coarse	Use fresh beans and make the grind finer
Coffee flows from one side of the portafilter	Coffee not tamped evenly	Tamp level and evenly with the tamper

Cleaning and Maintenance

Regular cleaning is important for preserving espresso flavor and ensuring a long machine life. The Mini Barista has a CLEAN program for daily cleaning and a descaling program against limescale that forms depending on water hardness. The brushes included in the box are used to clean the grinder, burr disc and group head.

The steam wand should be wiped with a damp cloth after each milk frothing and briefly purged with steam to remove any milk residue inside. You can watch the steps of general cleaning, grinder cleaning, the CLEAN program and the descaling program in the Mutbex video. For more information, you can read our article Espresso Machine Cleaning and Maintenance Guide.

Display Warning Codes

The Mini Barista informs the user with codes shown on its display. Most of these codes are not faults but warnings waiting for an action from the user. The two most common codes are the EP and nF warnings. The water tank running empty during the descaling program can trigger the EP warning, while the program being interrupted can trigger the nF warning. You can watch the solution to the EP warning in the Mutbex video.

Code	Meaning	Solution
EP	The water in the water tank has run out.	Fill the water tank and the machine continues from where it left off. During the descaling program, make sure the water tank is full before moving from step d3 to step d4.
nF	The descaling program was interrupted before completion.	Restart the descaling program from the beginning and complete all steps.

nF Error and Descaling Steps

The nF warning usually appears when the process is interrupted or left unfinished for any reason while the descaling program is running. In this case, the program needs to be restarted with the correct steps and completed to the end.

In the Mutbex video, the cause of the nF warning, how to start the descaling program and common mistakes made during the process are explained step by step. Descaling frequency varies depending on the hardness of the water used. To find out the water hardness in your region, you can read our article Türkiye Water Hardness Guide 2026.

Coffee Beans for Espresso

Thanks to the built-in grinder, coffee beans are freshly ground for every cup with the Mini Barista. Medium or dark roasted beans are generally preferred for espresso. Storing beans in an airtight container away from light helps preserve their aroma.

For example, Addis Ababa Coffee Sebata Blend is a blend of dark roasted Ethiopian beans produced specifically for espresso. According to the product page, the coffee offers an intense and lasting crema, with fruity, citrus and floral tasting notes. Since it retains its coffee character when used with milk, it is also suitable for preparing lattes and cappuccinos. Different bean options are listed in the coffees category.

Frequently Asked Questions

Is a separate coffee grinder needed with the Mini Barista?

No, the Mini Barista has a built-in steel conical burr grinder. Coffee beans are placed in the 250-gram hopper and ground to the desired fineness with the 15-step adjustment. This way, freshly ground coffee is used for every cup.

Can lattes and cappuccinos be made with the Mini Barista?

Yes, lattes and cappuccinos can be prepared with the machine's milk frothing wand. Thanks to the dual boiler design, milk frothing can begin immediately after the espresso is brewed. The pitcher included in the box can be used for milk frothing.

What does the EP code on the Mini Barista display mean?

The EP code indicates that the water in the water tank has run out. When the water tank is filled, the machine continues from where it left off. During the descaling program, the water tank must be full at step d3.

How often should the Mini Barista be descaled?

Descaling frequency varies depending on the hardness of the water used and how intensively the machine is used. In regions with hard water, descaling is needed more often. The process is carried out step by step with the machine's descaling program.

Why does the Mini Barista have a 20 bar pump?

20 bar is the maximum pressure capacity the pump can produce. The target pressure for espresso extraction is approximately 9 bar. The high pump capacity helps maintain stable pressure during brewing.
