Brewing Coffee Methods

There are many different methods of brewing coffee from instant coffee in a cup to bulk brewing for large events.Industrial Coffee Grinder  Depending on the method being used, the grind of the bean will differ.  Coffee beans should not be ground until they are required, this will help keep the coffees strength and flavour.

Coffee will lose the majority of its strength and flavour in the first twenty minutes after grinding.  If ground coffee is purchased, this should come in pre-portioned bags that are vacuum sealed for freshness.  The amount of coffee in each sealed bag will be determined by the amount of coffee an individual machine can brew.

Bellow are some guidelines to be observed when brewing coffee:

  • Only use freshly ground coffee
  • Buy the correct grind for the machine being used.
  • Use the set measure of coffee to water (283.5-340 grams per 4.5 litres)
  • Water must be boiled to extract the flavour, most machines will brew coffee at 82°C.  The temerature is then controlled to avoid coffee turning bitter

Following the above guidelines will produce a fresh coffee which should have a good aroma, flavour, body and when milk is added a good colour.  Some reasons for bad coffee are

  • water not hot enough or not fresh
  • insufficient or too much coffee used
  • stale or old coffee used
  • incorrect degree of roasting or grind for equipment being used
  • equipment is not clean
  • coffee may have been reheated
