Buying Guide- Espresso machines

Choosing the right espresso machine takes time. When selecting an espresso machine, the following factors should be considered:

  • Coffee preferences of the user/s
  • What volumes of coffee are required
  • Budget/decor

This buying guide will help provide a start in the selection of a machine. The next step is to contact us for a discussion of pros and cons of your short-list. The perfect machine for you will be the one which best meets your requirements. It’s our role to showcase the good and not so good about each machine to help you to make the right decision.

In general, espresso drinkers can often be well served with relatively simple machines. Where milky coffee is a priority, more complex machines may be appropriate.

Why can’t I just push a button for my coffee?

Machines which “do it all for you” are referred to as super-automatic machines. These will grind and extract the coffee. Some will also heat and add milk automatically. These machines are complex by nature and are produced by companies like Saeco, Jura and Delonghi. Sadly, they will not produce coffee at the standard you would expect to find in even an average cafe. Many purchasers are ultimately disappointed with their performance and come to realise that far better coffee can be obtained from a semi-automatic coffee machine when supplied with freshly ground coffee and when the user has received adequate training and/or viewed online training resources to learn how to use their machine. Talk Coffee does not sell super-automatic machines because we promote great coffee.

How about capsules/pods?

This style of coffee is everywhere. Whilst the machines are often inexpensive, the pods to operate them are very expensive and frequently end up in landfill. Pod machines might be likened to cheap printers from the local store. You purchase the printer for a tiny sum but are then locked into high-priced consumables for the life of the printer. With pods, the coffee can often be in excess of $100/kg. In our opinion, pod coffee is even less desirable than coffee from super-automatic machines as pods contain pre-ground coffee. Coffee beans stale within minutes of being ground- regardless of claims pod manufacturers may make. We do not sell pod machines either!

Do I need a grinder?

In a nutshell, yes! As coffee stales rapidly once ground- regardless of packaging and marketing spin, a grinder is required. In fact, whilst many purchasers would consider a machine and then a grinder, we would strongly recommend that a quality coffee grinder should be the first purchase. A satisfactory inexpensive grinder will cost a minimum of about $250 and in general will not have the longevity nor performance of a small commercial grinder which may be $500 or more. See our buying guide for coffee grinders for further information.

Grinder and machine combined?

Many companies manufacture combination machines. In general, we recommend against them. Coffee beans are best kept cool and should the grinder or machine section fail, there is no way to make coffee at all.


Ok, so how much will I need to spend?

Budget will be dictated by the planned use of the machine and how many people will be using it:

Singles or couples. Primarily espresso/long black with occasional milk coffee. Never more than 2-4 coffees in a session.

Single boiler machine:

single boiler machine

For this type of use, a single boiler machine may suffice. Single boiler machines will produce an espresso and if milky coffee is required, the user then pushes a button to further heat the boiler to produce the steam required to texture the milk. At this point, the boiler may well be empty and the element is hot. These machines do not have a internal control board or “brain” and if the steam control is left on, the element may fail. Boiler repair will generally result in an account of over $200. To remove the risk of element failure, these machines require boiler priming before use and immediately after milk texture. As a result, we do not recommend this style of machine for novices, offices, busy families or multiple users. They are best suited to experienced users.

Price range circa $700-1000. Simple single boiler machine/PID controlled single boiler machine.

silviaIn this price range. Boiler temperature is controlled by a simple and cheap bimetallic strip thermostat. As the temperature of the espresso can vary substantially, a cooling flush or “temperature surfing” is often required to achieve consistent espresso. In general, we do not recommend them. Better temperature control can be achieved with the incorporation of a PID temperature controller. These controllers will provide extremely accurate shot temperature control- at a cost. All other aspects of operation of the machine are identical to any other single boiler machine. These machines can produce satisfactory coffee in the hands of an advanced user and we can refer you to a reseller of them if you are seeking one.

Price range circa $1600. e-61 single boiler machine.

domobar piccoloAt this price point, the highly acclaimed e-61 group is introduced into the espresso machine. Consisting of around 4.5kg of solid brass, this group contributes to impressive temperature stability. e-61 single boiler machines are highly regarded as fantastic shot machines. Their boilers are much larger and as a result will cope admirably with higher volumes of coffee and milk. The Vibiemme Domobar Piccolo is an example.

Families, offices, singles. Primarily espresso/long black with higher requirements for milk coffee. At times, more than 4 coffees per session- dinner parties etc. Heat Exchanger (HX) machines:

hx mahcineHeat exchanger machines offer the true “cafe at home” experience. They have the ability to produce espresso and texture milk simultaneously. Heat Exchanger machines will cater easily for families, gatherings and offices. All have water tanks of over 2 litres and more expensive models have commercial rotary pumps. Machines with rotary pumps are quieter in operation and may be plumbed to mains water connections if required. HX machines may be operated by simply raising or lowering a lever or with a simple toggle switch or rocker switches. Some HX machines have volumetric buttons to deliver a predetermined shot length. Volumetric machines can carry a price premium of up to $500 over non volumetric machines from the same range. 

Price range circa $1500-3000. Entry level heat exchanger (HX) machine.

domobar juniorMachines in this category will cater for any size gathering but operate only from their internal water tank which must be refilled. They have simple vibration pumps and cannot be plumbed to a mains connection.New to range in 2017 is the Nuova Simonelli Oscar II which is available for under $1500. The Isomac Tea Due, Rocket Espresso Appartamento and Rocket Espresso Giotto Tipo V and Mozzafiato Tipo V are high quality, popular examples. Whilst you may read about the requirement for “cooling flushes”, well-calibrated e-61 HX machines will not require a cooling flush. 

PID in a HX machine?

Many who are looking for an espresso machine read about PID controlled espresso machines. A PID will make little difference to the performance of HX machines and referring to the diagram above delivers the answer as to why. HX machine groups receive what is essentially flash heated water from a tube in the boiler. Using a PID to alter the boiler temperature up or down by a few degrees will make little, if any difference at the group. A PID works best in a multi-boiler machine where it can be used to deliver real differences in brew temperature. The ability to “play” with brew temperature can be significant to those with great palates who are into black coffee/espresso. A change to brew temperature can be difficult to distinguish in milky coffees.

I read about cooling flush in a HX machine?

Time to visit the dress up wardrobe for some ye olde clothing when this point is raised. Here’s why…

In olden days (and still in some areas of Italy), espresso blends often contained a very high percentage of robusta beans. These high robusta coffees require a high extraction temperature (up to 96 or more deg. C) and Italian machines were manufactured to “run hot” to get the best from these coffees. Our Australian coffees tend to be low in robusta coffee or 100% arabica coffee. They work well at lower temperatures; 92-94 deg. C is commonly recommended. As a result, Australian buyers of olden Italian machines suffered with burned shots or flushed water through the group to achieve a cooling flush.

These days, reputable Australian importers have their HX espresso machines configured to idle in that ideal 92-94 deg. C range. The nett result is that you rinse the group (good hygiene) and simply use the machine.

There are still some imports of hot running HX machines into Australia. Talk Coffee will not sell poorly configured machines. It’s another reason why it’s not advisable to purchase a seat for a European sourced machine on your flight home after your trip to the continent.

 Price range circa $3500. Upper level HX machine.

They have commercial rotary pumps and are much quieter in operation. The Rocket Espresso Giotto Evoluzione R and Mozzafiato Evoluzione R are popular examples.

Advanced User. Price range >$3500. Those users requiring maximum control over espresso quality. Dual boiler machine:

These machines offer ultimate control and flexibility. Most are classified as small commercial machines although they can be quite compact.  They generally have rotary pumps and can be plumbed or run from an internal water tank. All have PID control of shot temperature and this can be useful for black coffee drinkers who like to experiment with roast depth and new “third wave” light roast coffees in pursuit of fruit notes and flavour. Most offer low energy modes where the steam boiler can be powered down if not required. Popular examples include the LaMarzocco GS3, Rocket Espresso R58 and the Izzo Valexia Duetto. .

Lever pull machines:

_MG_7089cremina-2What’s old is new again with these machines. They are silent as there is no pump. As a result, they require a mains connection. Shot quality is outstanding as the waning pressure profile minimises the likelihood of unpleasant tertiary extraction in the espresso shot. Many of our clients purchase a variety of espresso machines and then ultimately settle on a lever machine- forever. The romance and beauty of these machines combines with some of the best espresso possible. They are in a nutshell, coffee nirvana. An example is the Izzo Valexia Leva. The Olympia Express Cremina offers an expensive, Swiss manufactured alternative the to the much larger spring lever machines.

 Pressure profiling/Flow profiling machines. $6000 upwards

vesuvius demoPressure profiling is the latest buzz word in coffee. Commercial machines such as the La Marzocco Strada EP have demonstrated that the ability to vary extraction pressure within a shot can bring out the absolute best attributes of any coffee. The ACS Vesuvius is a ground breaking prosumer level machine which allows for pressure profiled extractions and a whole lot more. This astonishing machine has raised the bar for domestic espresso. Rocket Espresso have also entered this market with their R60V. The one group Slayer offers flow regulation via an adjustable needle valve.
