Elderflower sparkling wine

[Cobnut]

I’ve made this a couple of times in recent years using what seems to be the conventional water, sugar, lemons, elderflowers and champagne yeast recipe with some success. As the elderflowers are finally showing signs of appearing locally, my mind is turning to this again, but I’m wondering whether to amp it up a little and make something grape based, but with a strong showing of elderflowers.

I have no experience of wine making, so seeking advice and/or opinions as to how to approach this.

Or indeed whether it is worthwhile.

I make elderflower champagne every year. I use Berry's recipe for rhubarb wine and add the elderflower when I rack it into secondary.
