A spritz that behaves like the real thing: a ruby rhubarb-hibiscus cordial steeped with grapefruit peel and roasted dandelion root gives you genuine bitterness and tannic grip, not just fruit juice. It's short-shaken with verjus and fresh grapefruit to build texture, then lengthened with something cold and sparkling and garnished properly — big ice, expressed citrus oil, an olive on a pick. Make the cordial once and you can pour aperitivo hour for a week.
Ingredients
Bitter Rhubarb-Hibiscus Cordial (makes about 1 1/3 cups)
12 oz rhubarb stalks, trimmed and cut into 1-inch pieces (about 3 large stalks; frozen works)
1 cup water
3/4 cup granulated sugar
2 tbsp dried hibiscus flowers, loosely packed
1 large red grapefruit, peel removed in wide strips (reserve fruit for juicing)
1 tbsp slivered grapefruit pith (the white layer, scraped from 2 peel strips)
1 oz verjus (or 3/4 oz white grape juice plus 1/4 oz fresh lemon juice)
1/2 oz fresh grapefruit juice, strained
4 oz chilled non-alcoholic sparkling wine or plain sparkling water
large ice cubes
Garnish
1 navel orange, cut into thin half-wheels
4 Castelvetrano or other green olives
4 wide strips grapefruit peel, for expressing
Instructions
Make the cordial base: combine the rhubarb, water, sugar, and 1/4 teaspoon fine sea salt in a small nonreactive saucepan. Bring to a bare simmer over medium heat (small bubbles at the edge, about 185°F), stirring until the sugar dissolves, then cook 10 to 12 minutes, until the rhubarb has completely collapsed into a rough pink pulp.
Kill the heat and add the bitters: off the heat, stir in the hibiscus, wide grapefruit peel strips, slivered grapefruit pith, dandelion or chicory root tea, and the rosemary sprig. Cover and steep exactly 20 minutes — go much longer and the pith and root turn harsh instead of pleasantly bitter.
Strain: pour through a fine-mesh sieve set over a bowl, pressing gently on the solids with the back of a ladle to release liquid but not so hard that you push through pulp (cloudy is fine, muddy is not). You should have about 1 1/3 cups. Stir in the 1 tablespoon lemon juice. Taste: it should read sweet-tart first, with a clean bitter finish that lingers a few seconds.
Chill the cordial in a covered jar for at least 2 hours, or up to 3 weeks in the refrigerator. Chill your glasses and your sparkling wine or water hard — a spritz lives or dies on temperature.
Build one drink: combine 1 1/2 oz cordial, 1 oz verjus, and 1/2 oz fresh grapefruit juice in a cocktail shaker with 3 or 4 ice cubes. Shake briskly for 8 to 10 seconds, just long enough to chill and aerate; you want a light froth, not a slushy dilution.
Fill a large wine glass or stemmed tumbler with 3 or 4 big ice cubes. Strain the shaken mixture over the ice, then add 4 oz chilled non-alcoholic sparkling wine or sparkling water, pouring down the side of the glass to protect the bubbles. Give it one slow lift with a bar spoon from the bottom up — no more.
Garnish and serve: hold a wide strip of grapefruit peel skin-side down over the glass and squeeze to express the oils across the surface, then drop it in. Tuck an orange half-wheel against the inside of the glass and add a green olive on a pick. Serve immediately, while it's still bristling with bubbles. Repeat for the remaining 3 drinks.
Chef's tips
Frozen rhubarb is genuinely as good here as fresh — no thawing needed, just add 2 extra minutes of simmering time.
The bitterness comes from three places: grapefruit pith, roasted dandelion or chicory root, and hibiscus tannin. If you can only find one, use a full 2 tablespoons of slivered grapefruit pith and steep 18 minutes.
No verjus? White grape juice with a squeeze of lemon mimics its winey acidity closely. Unsweetened white cranberry juice also works.
For a party, pre-batch the shaken portion: multiply cordial, verjus, and grapefruit juice by the number of drinks, stir together in a pitcher, and refrigerate up to 8 hours. Pour 3 oz per glass over ice and top with sparkling.
Save the strained rhubarb pulp — stirred with a spoonful of the cordial, it's an excellent topping for yogurt or ice cream.
Rim variation: a light dusting of grapefruit zest mixed with flaky salt on the outer edge of the glass makes the drink taste even more aperitivo-bitter.
