Coffee Brewing Methods

 

Introduction

When you get into coffee, you will hear words like steeping, percolator, … What are they?

 

Coffee Filtering

No two people are looking for the same taste in their cup. In order to archive preferred flavor, you need to experiment with ground size, coffee to water ratio, and brew time. For starter, use 5 to 7g of coffee to 100 ml of water. Water should be 88 degree Celsius to 92 degree Celsius.

This method entail slowly pouring water over coffee grounds on a filter. Gravity draws water down through the ground to produce a coffee.

 

Percolator

Percolator is known for their ease of use and were popular in 1950s. It became unpopular because percolator coffee isn’t very good. Percolator reboils the coffee as it brews, recirculating the coffee over and over again, resulting in extremely bitter brew and coffee.

The percolator has two Chambers: the top chamber and bottom chamber. The top chamber holds coffee grounds, while bottom chamber holds water. To use percolator, put coffee grounds in top chamber, and water in bottom chamber, and place percolator over heat source.

The water in bottom chamber boils and is forced through a tube to top chamber over coffee grounds. This action is repeat over and over again until you turn off the heat source.

Steeping (french press)

Steeping is simplest way to make coffee. Just mix hot water with or and coffee grounds, wait some time, then separate the coffee grounds. The french press works on steeping.

Brewer must control the brew time, wait too long and separate the ground, you will have bitter coffee, wait too short, you will have weak coffee.

Vacuum Filtration

The vacuum filter has three parts – bottom chamber for serving, upper chamber for extraction, and a filter.

To brew, fill lower chamber with cold water, place ground coffee in upper chamber, and place entire apparatus over the heat source. As water heat, water is push up through filter into upper chamber, and water will 3coffee from the grounds.

When heat source is turn off, lower chamber cool faster, creating a vacuum and this vacuum sucks the coffee from upper chamber into lower chamber and can be served.
