John Innes compost

I was sitting in the GH this afternoon with the tedious task of pricking out Lobelia, I’d contemplated the universe and beyond, just trying to take my mind off the task, then got to thinking about my bag of compost.
Levingtons Professional with added John Innes and enriched with recycled materials.
Now, I thought compost was recycled materials, what was it before it was enriched? An empty bag?
Now the John Innes bit, what turns a bag of compost into a John Innes, it looks like one, two or three handfuls of grit and sand in equal measures.

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    Before it was peat based. Now you get the rubbish that people like me send to the council to get rid (Bindweed, marestail etc)
    John Innes institute worked out a formula for various loam based composts and also  what they called "base" fertilizers. Different strengths for different uses.

    The RHS website gives the John Innes composition but I've found it to be very variable between brands. If you avoid the peat based ones they seem to be sand, soil and coconut fibre now.
