About Coffee Percolators
Coffee percolators offer a traditional way to prepare strong, full-bodied coffee using a continuous brewing process that repeatedly passes hot water through ground coffee.
Electric coffee percolators combine this classic brewing method with the convenience of a plug-in appliance, making them suitable for everyday use at home, in offices or when serving several people at once.
What is a coffee percolator?
A coffee percolator is a coffee-making appliance that heats water and circulates it repeatedly through ground coffee during brewing.
As the water heats, it travels upward through a central tube before passing over the coffee grounds and returning to the main chamber.
This cycle continues during brewing and produces the bold flavour traditionally associated with percolated coffee.
How does an electric coffee percolator work?
An electric coffee percolator contains its own heating element, so it does not need to be placed on a hob.
Water is heated inside the appliance and circulated through the coffee grounds until brewing is complete.
Electric models can provide a convenient alternative to traditional stovetop percolators because the heating process is controlled by the appliance.
What does percolator coffee taste like?
Percolator coffee is often associated with a stronger, fuller-bodied flavour than many standard drip brewing methods.
Because the hot water repeatedly passes through the coffee grounds, the extraction process can produce a robust cup of coffee with a pronounced aroma.
The final flavour also depends on the coffee beans, grind size, coffee-to-water ratio and brewing time.
Coffee percolator vs filter coffee machine
A filter coffee machine usually passes heated water through the coffee grounds once before the brewed coffee collects in a jug.
A percolator repeatedly circulates hot water through the coffee grounds during the brewing process.
The two methods therefore produce different styles of coffee. Filter machines tend to provide a lighter brewing process, while percolators are traditionally associated with a stronger, more robust result.
How much coffee does a 1.8L percolator make?
A 1.8L coffee percolator offers enough capacity for several cups of coffee in a single brew.
Depending on cup size, a 1.8L Blackmoor coffee percolator can make approximately 9–12 cups, making it useful for families, offices, meetings and entertaining.
Do coffee percolators need paper filters?
This depends on the model.
Blackmoor's current electric coffee percolator uses a removable reusable filter, meaning there is no need to purchase disposable paper filters for normal use.
Reusable filters should be cleaned according to the manufacturer's instructions after brewing.
What is a keep-warm function?
A keep-warm function is designed to help maintain the temperature of brewed coffee after the brewing cycle has finished.
This can be useful when preparing several cups at once because you do not need to serve all of the coffee immediately.
How to choose the best coffee percolator
When choosing a coffee percolator, consider:
- Brewing capacity
- Number of people you normally serve
- Electric or stovetop operation
- Reusable or disposable filtration
- Keep-warm functionality
- Ease of pouring
- Ease of cleaning
- Available kitchen space
A larger electric percolator can be particularly useful if you regularly make coffee for several people, while a smaller model may be more suitable for individual use.
Frequently Asked Questions
-
A coffee percolator is a coffee maker that repeatedly circulates heated water through ground coffee during brewing. This traditional brewing method is known for producing a strong, full-bodied cup of coffee.
-
Percolator coffee can taste stronger and more robust because water passes through the coffee grounds repeatedly rather than just once. The final strength also depends on the amount of coffee used, grind size and brewing time.
-
A 1.8L percolator can make approximately 9–12 cups depending on the size of each serving.
-
Not necessarily. The current Blackmoor 1.8L Electric Coffee Percolator uses a removable reusable filter, so disposable paper filters are not required for normal operation.
-
The current Blackmoor electric percolator includes a keep-warm function designed to maintain the coffee's temperature after brewing.
