Cold drip coffee is produced by slowly percolating chilled filtered water through freshly ground coffee over many hours.
With the cold drip process the coffee grounds are never soaking in their own infusion (an important differentiation with cold brew coffee), instead fresh water flows slowly but continuously through.
As heat is not used at any part in the process, cold drip can successfully extract a sweeter flavour from the coffee bean. It can highlight the deepest of chocolates, caramels and spices or the lightest fruit with a texture unlike any other brewing method.
It’s thought that a version of cold drip coffee originated with Dutch sailors in the 17th century!
