Quick Summary

Percolation is a process where a liquid slowly filters through a permeable substance. This can be a physical process, like water seeping through soil, which can help purify the water. It can also be used in chemical contexts, such as a solvent passing through a substance to extract a soluble component.1

The term "percolate" comes from a Latin verb meaning "to put through a sieve". In a chemical context, percolation is a type of separation process. It's also used to describe how awareness or ideas can spread gradually through a population.12

In percolation, water is brought to a boil in an urn and fed up a tube to a basket holding the coffee. After filtering through the coffee, the water drips back to the urn, where it is forced back up the tube and recirculated until the…

Leaves or herbs are placed in the top section, and the base spirit in the bottom section is pumped up over the flavouring material, extracting and carrying down the flavour constituents.…
