I have turned the grapes into juice and have 6 and 1/2 drinks containers of juice as a result. At the moment they still need to settle having been ‘whizzed’ through a juicer rather than crushed under foot. I simply don’t have time for that. I’ll leave them covered like this for a few days and then skim what is left at the top and decant the juice into some bottles. Given each of these are about a litre I wasn’t far off on my estimate of just over two bottles of grape juice.
