I have 3 half filled jam jars of red wine with muslin covers currently sitting in the kitchen, in the hope it will produce its own 'mother' eventually, but it could take months, if it happens at all!
I,ve never seen it for sale here, and I have searched the internet exhaustively. USA sites have an abundance of the stuff.
I,ll go to plan B if I can,t find it, which is to use unpasturised cider vinegar, but I,m not sure if it,s ok to use it with the red wine!

I have a sad, lonely, empty vinegar jar just waiting to become a productive member of the household, so any sightings would be much appreciated
