Rob Collins (Elderflower Vodka Collins)
A bright, floral twist on the classic Collins. The Rob Collins shakes vodka, elderflower liqueur, and lemon juice for a crisp, refreshing cocktail that balances sweetness with a citrus snap.

A floral, vodka-based Collins that blends honeyed elderflower with fresh lemon and fizzing soda. Light, aromatic, and perfectly sessionable for warm days or brunch hours.
Background
The Rob Collins modernizes the Tom Collins formula by swapping gin for vodka and sugar for elderflower liqueur. This update became popular in the 2010s as bartenders sought softer, more aromatic takes on the Collins family.
