Well coffee and tea just use the beans/leaves.
With ingredients with a high moisture content (fresh ginger, for example), I have pulsed with an absolute load of salt, then it will be all clumpy, spread it on a baking tray lined with parchment paper, and dry it under a radiator or in a laundry closet or somewhere similar (oven on a really really low temp will work I would imagine), after a few days all the moisture has gone, it will be one hard block, break it into pieces and stick it all into a blender and blitz it.
Perhaps if you reduced a bottle of red wine down by about 75% and then mixed with salt like in that method it would work.
