Elderflower Water

Has anyone tried this? “The delicate taste of hand-picked elderflowers blended with our sparkling Cotswolds spring water. Serve simply over ice or use as an alternative to tonic when enjoying botanical gin.”
Ryan tried it when we stopped by Grounded Coffeehouse yesterday. I had a sip, was quite jealous, and have been craving it ever since. It’s just so delicate and reminds me of… something. I can’t figure it out.
So if you see this, try it. And then help me figure it out.
They also have a ginger & lemongrass one. Mmm.
i had never seen this before but yesterday i came across it at a market in mahone bay. it was delicious and very refreshing. surprising since i normally don’t like any kind of pop or juice. i want to try the other flavours. i noticed a cranberry and orange that looked zesty.
