Product Criteria Paper

of all coffee macines

).Therefore the following product categories for coffee machines

for private household use are defined in this paper (detailed description chapter 2.2.1

and 2.2.2):

 Fully automatic coffee machines,

 Portioned machines for capsules

 Portioned machines for pads

 Semi-automatic portafilter coffee machines

These types of machines are automatic single-serve coffee makers. Compared to the

traditional way of coffee making the advantage of these automatic coffee machines is -

from the environmental point of view – that they brew just as much coffee as needed.

Semi-automatic coffee machines like machines with piston lever are also single-serve

coffee makers. The only difference is that the consumer has to grind the beans by

himself and fill the coffee powder into the piston lever.

In comparison to filter drip machines, single-serve coffee makers help to save both

energy and coffee (beans/powder) as less coffee is wasted. But most of the

espresso/coffee machines sold so far have high power consumption. This is less due

to the actual coffee-making process than to the stand-by consumption. Based on an

average use of private households up to three quarters of electrical power is consumed

in standby mode

Not considered are filter coffee machines, combi-machines and (commercial)

appliances with a permanent water supply.

The energy consumption of filter coffee machines is dominated by their keeping warm

function. The power consumption for the coffee production is similar for all devices. A

typical filter drip machine uses approximately 27 kWh per year (assumptinos: 30

minutes keeping warmfunction and 2190 cups). Filter coffee machines differ from

devices mentioned above: they are not meant to brew coffee cupwise. For a good

coffee quality they have to brew a certain quantity of coffee (2-3 cups). Due to this fact,

the keeping warm function is not necessary for brewing additional cups but for keeping

warm the brewed coffee. A thermal jug perfectly fulfills this function: it keeps the coffee

hot and saves a lot of energy because the machine can be switched off directly after

brewing. As a consequence the most efficient filter drip machines are the ones with

thermal jug that do not need a keeping warm function.
