Making red champagne stage 1

I have never before made red champagne but have always wanted to try it. So yesterday I picked elderberries and blackberries to using champagne making. There area number of steps to the process. Yesterday, I pressed the fruit to extract the juice which has now gone into a fermenting bucket with sugar and a small amount of vinegar where it will remain for a few days. During the coming week it will be bottled - fermentation will continue in the bottles, giving it a fizz when opened.
