The percolating coffee pot was invented by the scientist and soldier Count Rumford, otherwise known as Sir Benjamin Thompson (1753–1814), who was a loyalist American colonist.
He invented a percolating coffee pot between 1810 and 1814 following his pioneering work with the Bavarian Army, where he improved the soldiers’ diet as well as their clothing. It was his abhorrence of alcohol and his dislike for tea that led him to promote the use of coffee for its stimulating benefits.
For his efforts, in 1791, he was named a Count of the Holy Roman Empire, and granted the formal title of Reichsgraf von Rumford.
His pot did not use the rising of boiling water through a tube to form a continuous cycle.
How to brew coffee using a Percolator
- Coarsely grind 60g of coffee and display the coffee in the metal filter.
- Pour 1 liter of cold filtered water in the percolator.
- Insert the filter filled with coffee in the percolator. Put the lid on.
- Plug your percolator in, and wait for the water to boil.
- As soon you see through the lid the boiling water brewing the coffee, count 4 minutes. Then unplug the percolator.
- Wait 1 minute before opening the percolator and removing the burning hot filter (use a cloth to grab the filter!)
- Stir then decant your brew before serving it.
