Bezzera Unica adopts the conventional E61 grouphead, which is always revered as the benchmark for commercial quality. This is a single boiler, it can’t brew and steam at the same time and it’s recommended for users who drink mostly in coffee black.
User video found online on Bezzera E61 extraction
The E61 groupheads had been used for decades for commercial usage.
Users can do preinfusion techniques if they find necessary.
The thermosyphon system will cycle hot water to the grouphead just like any E61 system.
Brew Pressure Gauge
Features an important brew gauge, useful for identifying any anomalies during brewing and a PID temperature controller to ensure your machine is ready at the right temperature.
The E61 uses a thermosyphon system to stabilise the temperature of the grouphead.
For the E61 grouphead with a single or heat exchanger system, if the boiler is lower than 2 litres. It’s found to be very unstable in the temperature during extraction. As there’s too much displacement of hot water out with fresh cold water pumped in. It will create a drastic drop in temperature in the boiler which then lead to a lowered temperature in the grouphead from the themosyphon system.
To overcome this, the Unica’s boiler does not refill boiler on its own, the user will have to top up manually after the extraction, so cold water won’t get mixed in during the extraction process. This increases the stability of the temperature.
The machine comes with a PID temperature controller. The user will use that to set whether the machine is in steam or coffee mode. The PID has an easy to read display to tell the user what temperature the machine is on.
A safe material with natural anti-microbial properties to continuously kill 99.9% of bacteria that cause hospital-acquired infections, keeping water in the boiler always potable. One of the most conductive metal on earth, making the machine very efficient in starting up and recovering from lost heat. Will never rust like stainless steel, or release lead from Brass, will only oxidise and increase its antimicrobial properties as its age.
High-quality Bezzera boiler.
Many manufacturers purchase their components from 3rd party vendors around the world, of unmeasured quality and reliability. Bezzera welds and makes all their boilers from their factory in Milan. Boilers are tested at high pressure to ensure that they are safe for usage.
Food Grade material
A few years ago, users from Europe had found out that many espresso machines, including cafe machines, are leaching huge amount of toxic metal. That includes aluminium, lead and other metal that can cause bioaccumulation and toxification. Potentially causing organ damages, cell mutations and other complications.
Bezzera’s machines were found to be among the safest, topping the result in lab tests as compared to its peers. It’s interesting to know that some machines with stainless boilers, which were claimed to be safer, actually fared much worse with high level of lead detected in the water.
That’s possible because Bezzera is a real factory that produces most of its main parts inhouse, with full control over its production and parts. With ample experience of over 100 years and huge amount of R&D done to understand what’s best for the machine, and also the user. The machines are safe enough for us to feel assured that they can be used by our own family
Bezzera scrutinize all their suppliers with the most stringent requirement, in both performance and material integrity. All parts are produced in Italy and most parts by Bezzera themselves. This is a stark difference compared to many companies who outsource or purchase components wholesale and only does assembling in their factory without much tests or evaluations done.
Not only that, we are pleased to inform you that all newer machines are now equipped with a new generation of fittings and parts that make the safe material they use, significantly safer. This is the type of quality that you can’t see in the specifications.
The E61 system can easily produce a good espresso.
However, because the Bezzera Unica is a single boiler, it can’t brew and froth at the same time. If you do thought of drinking cappuccino, the machine has to be manually set to steam mode and it can still produce a good amount of steam power. Thus, it’s more recommended for users who prefer drinking espresso mainly.
The PID can ensure that the temperature remains constant with little variance.
Warning: Be careful of hot surfaces, water and steam at all time.
Do not allow vibration pumps to activate for more than 2 minutes, allow a half amount of rest time for any long duration of activation .
Do note that the boiler has to be refilled manually, particularly for the opening use and after frothing extensively. Failure to do so, will dry the boiler and cause damaged to the heating element which will not be covered by the warranty.
