"Here we have super-refreshing and sophisticated flavours," says Ashton. "The grapefruit rosé provides a pleasant bitter-floral base, with the sumac syrup and Chambéryzette adds the sour-sweet balance that makes this Spritz so quaffable." Start this recipe a day ahead to make the grapefruit rosé.
Note "Chambéryzette, a strawberry apéritif, is available from major liquor retailers, and is worth hunting down, not least for the beautiful packaging," says Ashton. "It would be possible to substitute with a 50-50 mix of dry vermouth and strawberry liqueur, but this will ultimately cost more than just buying the Chambéryzette. It's also delicious by itself over ice or topped with a splash of sparkling wine."
