Steeping E liquid in our case is a process or the many processes the e liquid goes through in order to extract the BEST flavour for vaping. Imagine a cup of tea - it's always best when the leaves are steeped in hot water to release the flavour and nutrients before drinking - when it's brewed properly it make for the perfect cuppa. This concept can be applied to how we steep our liquids to extract the very best out of them. Before they're ready to be used, we need to remove the harsh edges and round them off by maturing or ageing them.
