Yep, it's from Dahl. Loved him as a kid and am starting to build up a collection to read to my daughter.
I picked up the second Charlie book recently and reread it only to discover that for 10 years of going by this handle I have been misspelling it. Supposed to be Vermicious. Oh well.
As for the cider, I hope that some more experienced cider brewers will chime in or if some of the others that have posted are more experienced, please tell me if I am off base, but I understand that this is the natural progression for cider. Horrible smell and taste for many months before finally cleaning up.
Never mind, I think I finally understand what delboy is saying. If it truely tastes like vinegar, use it in your garden or for salads. If it only tastes and smells sour, that's just how green cider tastes.
