This really neat bread starter goes from grapes and wholemeal flour to a sourdough yeast starter in just 9 days. Uses fresh unwashed red or purple grapes.
Use unwashed, organically grown red or purple grapes for this recipe. The white powder found on the skins of the grapes is used as homemade starter yeast for bread. If you wish, you can switch to plain flour on the fifth day.
I used shop-bought red grapes with good luck. The flavour is truly sourdough. - 14 Jul 2008
I was glad to find this recipe, as I had only read references to this starter. It resulted in a nice tangy starter and was interesting to make - 14 Jul 2008
I used wine grapes from a local vineyard. This makes a very fast "sourdough" starter, with a less sour flavour than my regular sourdough. It has worked in all my favorite sourdough recipes that I have tried it in. - 14 Jul 2008
