Electricity cost usage of a Coffee Maker

A coffee maker or a coffee machine is a common kitchen appliance used to brew coffee by heating up water and dripping it through ground coffee beans. Most  coffee brewers can schedule automatic brewing  allowing users to set a time. While making coffee the coffee machine will use about 300 to 600 watts for 2 cups of coffee and 1000 to 1500 watts for 8-10 cups of coffee. The average coffee maker will use 800 watts to produce 4 cups of coffee in 10 minutes.

Click Brew It to find the energy consumption of a coffee maker using 800 Watts for 20 minutes (0.33 of an hour) a day @ $0.10 per kWh.

Hours Used Per Day: Enter how many hours the device is being used on average per day, if the power consumption is lower than 1 hour per day enter as a decimal. (For example: 30 minutes per day is 0.5)

Power Use (Watts): Enter the average power consumption of the device in watts.

Price (kWh): Enter the cost you are paying on average per kilowatt hour, our caculators use the default value of 0.10 or 10 cents.

A coffee maker will use approximately one watt of power in addition to the energy used for brewing. This equals to 24 watts a day and 8.76 kWh a year, which is not a significant amount of energy use.

How Much Ground Coffee Should I Use?

Calculates  how much ground coffee you should use when brewing, either with a cafetiere or drip coffee maker.

Find out how much ground coffee to use.

Volume of water:

ml fl oz

=  grams of coffee


 


In coffee, ratios of ground beans to water tend to be about the same regardless of brew method (espresso being, as always, an exception).

The well-endorsed industry standard ratio is about 1 part coffee to 18 parts water but many strong brew aficionados will go as strong as 1 part coffee to 13 parts water.

I think a ratio of 1:16 as a starting point in most  at home brewing.

Medium to Fine Grind: Coffee Drip Method

The time that the hot water stays in contact with coffee is shorter for the coffee drip method, compared to the other extraction techniques we discussed. This is one of the reasons for needing a finer grind than for the percolator or the French press, otherwise, if the grind is too coarse not enough coffee will be extracted. In addition, the filters used in these coffee makers are usually made of paper and can stop much finer particles than do the metal mesh filters in the French press or in the percolator. The medium to fine grind is somewhere between the coarse sand and coarse sugar.
