A southern Italian spritz built on limoncello, prosecco and sparkling water, popularised along the Amalfi coast. It is bright, sweet-sharp and yellow rather than orange. The alcohol-free version keeps the lemon front and centre with lemon syrup and Sober Spirits G 0.0%, whose botanicals stand in for the spirit base.

That is exactly what this recipe does. Limoncello is a sweet lemon liqueur at around 30 percent alcohol, so it has no alcohol-free equivalent on the shelf. Ten millilitres of lemon syrup restores the sweetness and the zest, and Sober Spirits G 0.0% restores the aromatic backbone the liqueur used to provide.

Syrup. Limoncello is made from zest, not juice, so its flavour is perfumed rather than sour; lemon syrup reproduces that. Fresh juice would turn the drink into a lemonade, sharp and one-dimensional. A few drops of juice on top of the syrup are fine if you want more edge.

Because limoncello is very heavily sweetened, and a classic Limoncello Spritz can use 50 ml of it. Here the sweetness comes from 10 ml of syrup alone, and Sober Spirits G 0.0% is sugar-free. The lemon character is the same; the sugar load is a fraction of it.

Untreated lemons with a thick, fragrant skin, since the slice sits in the glass and the zest is what you taste. Sorrento and Amalfi lemons are the reference, Menton lemons an excellent alternative. Waxed supermarket lemons leave a faintly chemical note in a drink this simple.
