A dry elderflower wine can taste like that without the tannins from the tea. With time those tannins may edge out. May want to consider serving with various fruit syrups to help balance things out, you will be amazed how a minimally fruit flavored elderflower wine tastes. I adore blending 75% dry elderflower wine with 25% sweet raspberry wine/mead. Caution, elderflower wine on its own has a tendency to cause nausea in many people. Plus, the ideas of turning into a spritzer upon serving is pleasant.
