I mixed this cocktail with a reduced amount of elderflower to 10ml. As said the lime zest twist is a must and so I noticed a little bit of peppermint. Nice.
Like the cocktail. Did feel the amount of Elderflower overwhelmed the subtle flavours of the Bison Grass Vodka. Lessening the Elderflower would make the cocktail a bit drier. Perhaps reducing the Elderflower by 5 ml.
