Champagne Cocktail Ratios (Kir, Bellini, Mimosa)

15 ml (1 part)

Kir Royale — crème de cassis — Dijon-style blackcurrant liqueur, typically 15–20% ABV

135 ml (9 parts)

Kir Royale — Champagne or sparkling wine — Brut preferred; the dryness balances cassis sweetness

60 ml (1 part)

Bellini — white peach purée — Fresh or frozen; yellow peach reads less sweet, shifts to 1:4

180 ml (3 parts)

Bellini — Prosecco — Extra dry style traditional; brut makes it more austere

60 ml (1 part)

Mimosa — fresh orange juice — Freshly squeezed only; carton juice kills the bubbles faster

120 ml (2 parts)

Mimosa — Champagne or Cava — Some recipes go 1:1 for brunch service; 1:2 is the elegant proportion

All three are built directly in a chilled flute — no shaking, no stirring beyond a single gentle lift with a bar spoon to integrate. For Kir Royale: add cassis first, then pour Champagne slowly down the inside of the glass. For Bellini: spoon purée into the flute, pour Prosecco, lift once from the bottom to blend without losing bubbles. For Mimosa: pour juice first, then Champagne — the reverse of Kir — since juice is denser and will integrate naturally as bubbles rise.

• Always chill the flute before building; warm glass accelerates bubble loss and dilutes nothing
• Fruit purées (Bellini) should be strained to remove fiber that traps bubbles and makes the drink go flat quickly
• For Kir Royale, use a Brut Champagne — the cassis adds enough sweetness; Extra Dry or Demi-Sec will tip the drink cloying
• Peach purée oxidizes quickly; prepare it no more than one hour ahead and keep refrigerated with a squeeze of lemon
• The 1:2 Mimosa ratio (juice:wine) is the restaurant standard; 1:1 is the brunch shorthand that sacrifices complexity for cost
• Never use a mixer or shake sparkling wine — carbonation is the structure; violent agitation destroys it
• Cassis varies widely from 15% to 20% ABV; adjust volume slightly for sweeter, lower-ABV versions to maintain balance

• Kir Imperial

  Raspberry liqueur (framboise) replaces cassis at the same 1:9 ratio

• Kir Cardinal

  Red wine instead of sparkling; cassis ratio stays 1:9 but loses the effervescence

• White Peach Bellini

  Original Harry's Bar recipe (Venice, 1948) uses only white peaches for their pale blush and delicacy

• Strawberry Bellini

  Strawberry purée at 1:3; needs a squeeze of lemon to brighten acidity

• Buck's Fizz

  British cousin of the Mimosa; orange juice to Champagne at 1:1, sometimes with a dash of grenadine

• Poinsettia

  Cranberry juice to Champagne at 1:3; orange liqueur added; holiday variation

• Aperol Spritz (3:2:1)

  Prosecco-forward spritz format; shares the sparkling-wine base logic

• Pisco Sour

  Also a precisely ratio-driven cocktail where texture modifier (egg white) determines foam

• Simple Syrup 1:1 vs 2:1

  Governs sweetness when cassis or a flavored syrup substitutes for a liqueur in Kir-style drinks
