Roger - think you will need to resort to the gallon demi-johns I'm afraid. We too got rid of all of ours and then 2 years ago our vine produced enough grapes to start making our own wine & we had to re-equip. Had a devil of a job tracking the equipment down. Wilkinsons sell the demi johns but all the other stuff like hydrometer, specific gravity measuring tube, filtration traps are hard to find. Only place we could buy them was a garden centre called Paradise Park, in Newhaven, East Sussex.
