I would call it a liquid feed and yes I did make it by adding NO WATER to the leaves (nettle and comfrey), so they just decomposed into a relatively sweet smelling liquid, with no putrefaction, and using it at anything from 20 to 50:1 dilution was a pleasure, no smell at all.
Compost tea is different, not the same thing at all, is made by aerating and stirring a small amount of high quality compost full of bacteria and fungi, to multiply them hugely. The resultant liquid is rich in life rather than nutrients and is not a liquid feed in the normally used sense of the word. The benefits are great but a snag is that you need kit (say £80 worth) and time, have a look at http://www.edaphos.co.uk.
