Peach Bellini

I went through six versions of this frozen cocktail trying to get real peach flavor without actual fruit. Peach extract has no depth once it hits carbonation, and flavored syrups taste artificial the moment you add bubbles. The Ultima mocktini electrolyte mix is what finally worked. It's blended specifically for a cocktail profile, so the peach flavor survives the prosecco instead of disappearing into fizz. One reader told me she tried six other keto bellini recipes and said this was the first where she stopped thinking about the substitution.

The technique takes about 30 seconds. Ice, vodka, dry prosecco, sweetener, and the mix into a blender, then blend until smooth. The frozen texture is what sets this apart from just stirring prosecco with flavoring in a glass. It feels like something from a brunch spot, not a diet drink. I've served these at two parties now. Both times the blender ran nonstop, and one friend who claims he doesn't do fruity drinks finished his glass and asked for a second before I rinsed the pitcher.

Dry prosecco is the piece most keto cocktail recipes get wrong. Sweet or demi-sec bottles can have 28 grams of sugar per glass, which wipes out your entire carb budget in one drink. I look for 'brut' or 'extra dry' on the label and check the nutrition facts before buying. A good bottle runs 1-2 grams of sugar per serving. Champagne works identically, and cava is a cheaper option with the same bubble structure. Skip the alcohol entirely if you want a mocktail: drop the vodka (the mix carries all the flavor on its own) and swap prosecco for sparkling water.

If you're making these for a group, I double or triple the recipe and blend in rounds so the ice-to-liquid ratio stays right. Pre-freezing your champagne flutes buys an extra 10 minutes before the texture starts to go. For more cocktails that won't wreck your macros, I have a keto mojito for summer, a vodka lemonade when I want something simple, and a hot buttered rum for cold nights. If you want another frozen blender drink, my frozen hot chocolate uses the same technique with chocolate instead of peach.

My Frozen Peach Bellini Recipe

I partnered with Ultima to build this cocktail around their Peach Bellini mocktini mix, and that partnership is the reason it works. The electrolyte mix captures that candied peach taste without actual peaches or sugar. Blend it with vodka, dry prosecco, and a little sweetener over ice, and you have a frozen cocktail in 30 seconds that won’t knock you out of ketosis. Want a mocktail? Drop the vodka and swap the prosecco for sparkling water. The mix carries all the peach flavor on its own.

Can You Drink Alcohol on Keto?

You can drink alcohol on keto as long as you stick to zero-carb spirits like vodka, rum, whiskey, and gin. They have zero sugar and zero carbs, so they don’t affect your macros directly. I use vodka in this recipe because it’s neutral and lets the peach flavor do the talking. The thing I always remind myself is that your body prioritizes metabolizing alcohol over burning fat. So I keep it to one or two cocktails and don’t make it a nightly thing. The carb count on the bottle matters less than the metabolic pause.

Choosing the Right Prosecco

Traditional bellinis call for prosecco, but not all bottles are equal. Some have as much as 28 grams of sugar per glass, which is an entire day’s carb budget in one pour. I always check the label for ‘brut’ or ‘extra dry’ and look up the nutrition facts before I buy. Anything labeled ‘sweet’ or ‘demi-sec’ is off the table. A good low carb dry prosecco runs 1-2 grams of sugar per serving. Champagne works the same way, and if you want to save some money, cava has identical bubble behavior at a lower price point.

Why I Use Ultima Electrolyte Mix

I’ve been using Ultima electrolyte mixes for years, and their sugar-free, zero-carb formula is what makes this cocktail possible. Their mocktini variety pack includes three flavors: Coconut Pina Colada, Appletini, and the one I use here. The electrolyte blend means you’re getting potassium, magnesium, vitamin C, and zinc while you drink, which matters on keto when alcohol dehydrates you faster than normal. I’ve built recipes around all three flavors, so if you like this one, try my sugar-free Appletini or the pina colada smoothie next.

The Story Behind the Bellini

The bellini was invented between 1934 and 1948 by Giuseppe Cipriani at Harry’s Bar in Venice. The original was white peach puree and prosecco with a splash of raspberry or cherry juice for that soft pink tint. Cipriani named it after the painter Giovanni Bellini, who used the same pink in a saint’s toga. I like knowing the history because it reminds me that a bellini is supposed to be simple: two or three ingredients, nothing fussy. That simplicity is what makes the frozen version work too. If you want to experiment, one of my readers swapped the vodka for peach schnapps at a Galentine’s party and said the dry prosecco kept it from going too sweet. I’d try that, or toss in a handful of frozen strawberries for a strawberry-peach variation.
