Apparently, the spritz originated in Venice when it was in the Austrian Empire, and was first what we'd call a spritzer: white wine with soda. However, it evolved, with the addition of a bitter liqueur, such as Campari, Cynar or Aperol.
Now the Aperol company benefits from free marketing as everyone calls it by the name of the bitters that gives it the orange colour. And what does Aperol itself contain? Gentian (a blue mountain flower), rhubarb, bitter orange, and cinchona, a shrub or tree that's a source of quinine, which contributes to the drink's bitter edge.
After a weekend of drinking Pimm's last week I was in the mood for a long, fizzy, slightly sweet summer drink. So last night I finally got round to buying a bottle of Aperol (Waitrose, £15). I did wonder about substituting Campari but reading the labels, I realised that Aperol is about 11% ABV, less than half that of Campari, keeping the overall alcohol content of the spritz to about the same as wine.
Handily, the recipe is printed on the label – three parts prosecco, two parts Aperol, one part soda water – so no online recipe research needed. Add the traditional slice of orange to serve.
