Water Brewing Temperatures
17 September 2014
You do't need to be fanatical about water temperature to get a good result with different brew methods . Simply letting your jug sit for 2-3 minutes after boiling will be enough time for the water to cool to between 90-95 degrees. This is where we want to extract our coffee, any hotter and we get the harsh bitter flavours, any lower and we get the sour and under developed flavours. Of course you can always get technical and buy yourself a water thermometer, to get the temperature spot on . One more important fact to note is the quality of water when home brewing either in a plunger or chemex try and use filtered water. It really does make a big difference. All commercial coffee machines run water filters that are changed at least every 6 months .
