I have foam action! Well, in one pot anyway. So I am feeling that I am half on my way. In fact, I can hear a very satisfying bubbling coming from the pot that is active. Perhaps I have added too much yeast?
Anyway, I have had a little taste of both mixtures and they still taste sweet, but still more like lemon rather than Elderflower. I am hoping that the fermentation will extract more flavour from the Elderflower.
I have added more yeast to the second pot and after checking it continuously throughout the day, there is action there too. And some more bubbling sounds. So, I will leave them now for four more days and hope that I do not end up with a cauldron of sourness.
Would really love to have any suggestions as to whether plastic bottles will keep my fizz fresh for 6 months or whether I need to use glass for the bottles I plan to keep after Christmas.
