A shrub — also called a drinking vinegar — is one of the most useful things you can make from summer fruit. Knowing how to make shrubs means knowing how to turn a pound of peak-season strawberries, blackberries, or peaches into a versatile, shelf-stable syrup that makes sparkling water interesting, elevates a simple cocktail, and works equally well as a mocktail base. The process involves maceration, mild fermentation, and vinegar — and the result keeps in the fridge for months.
Shrubs fell out of fashion in the era of refrigeration and came back in the craft cocktail revival of the 2010s. They're worth making for the same reason they were popular in the pre-refrigeration era: they concentrate flavor and preserve it in a form that's immediately ready to drink.
The Two Methods: Cold-Process vs. Wild-Fermented
Most shrub recipes call for the cold-process method: you macerate fruit with sugar, let it sit until the sugar draws out the juice, then add vinegar and strain. It's reliable and fast — a cold-process shrub can be ready in 2 to 3 days.
The wild-fermented method takes a day or two longer and produces something more complex. You macerate fruit with sugar and let the mixture sit at room temperature for 3 to 5 days before adding vinegar. During this time, wild yeast and bacteria present on the fruit skin begin to ferment the sugar. You get a slightly fizzy, more layered flavor that the cold-process method can't replicate — closer in spirit to something like fermented lemonade or a ginger bug-based soda, but finished with vinegar and used as a concentrate rather than drunk directly.
Both methods produce excellent shrubs. The cold-process is better when you want precise, clean fruit flavor. The wild-fermented is better when you want depth and complexity — especially with stone fruits like peach and nectarine, which develop extraordinary flavor when allowed to ferment briefly.
The Basic Formula
Regardless of method, the ratio is the same: equal parts fruit, sugar, and vinegar by weight. A simple starting point:
- 250g fresh fruit (about 1 cup, depending on the fruit)
- 250g sugar (white sugar, honey, or a mix)
- 250ml apple cider vinegar
This produces about 500ml of finished shrub syrup — 16 to 20 servings at the typical 1.5 tablespoon pour per drink.
You can vary the sweetener. White sugar produces the clearest, most neutral base that lets fruit flavor shine. Honey adds floral notes particularly well-suited to stone fruits and berries. Raw cane sugar has a subtle molasses note that works with bold fruits like blackberries and cherries.
Cold-Process Shrub (Ready in 2–3 Days)
Step 1: Macerate the fruit. Combine fruit and sugar in a clean glass jar or bowl. Muddle gently to break the fruit and mix with the sugar. Cover with a cloth or loose lid and leave at room temperature for 24 to 48 hours. The sugar draws juice from the fruit — you'll see a flavorful liquid pooling at the bottom.
Step 2: Add vinegar. Pour in the apple cider vinegar and stir to combine. If you used honey, you may need to warm the mixture slightly to fully incorporate it — but avoid heat if you can, as it dulls the fresh fruit flavor.
Step 3: Strain and bottle. Strain the mixture through a fine-mesh sieve or cheesecloth, pressing to extract as much liquid as possible. Transfer to a clean glass bottle or jar, seal, and refrigerate. The shrub is ready to use immediately but improves over the first week as the flavors integrate.
Wild-Fermented Shrub (Ready in 5–7 Days)
Step 1: Macerate and ferment. Combine fruit and sugar in a wide-mouth jar. Muddle lightly. Cover with a cloth and leave at room temperature for 3 to 5 days, stirring once a day. You should start to see very light bubbling at day 2 or 3 — a sign that wild yeast is active. The brine will smell fruity, slightly tangy, and pleasantly alcoholic. This is what you want. If anything smells unpleasant or looks moldy, discard and start over.
Step 2: Add vinegar and strain. When the mixture is actively bubbling and smells great, add the apple cider vinegar and stir. Strain through cheesecloth, pressing well. Bottle and refrigerate.
Keep the fruit submerged during fermentation
For the wild-fermented method, fruit pieces that poke above the liquid can grow surface mold. Press the fruit down with a spoon each time you stir, or use a small fermentation weight to hold everything below the juice line. This is especially important with larger fruit pieces.
Three Summer Shrubs Worth Making
Strawberry-balsamic shrub. Use 250g ripe strawberries, hulled and halved. Replace 50ml of the apple cider vinegar with 50ml of good balsamic vinegar. The combination of strawberry, balsamic, and a touch of ferment is extraordinary. Excellent with sparkling water and a sprig of basil.
Blackberry-ginger shrub. Combine 200g blackberries with 50g peeled fresh ginger, roughly chopped. Macerate with sugar as normal. The ginger ferments readily and adds a warming spice to the blackberry flavor. Finish with apple cider vinegar. Use as the base for a shrub mule (sparkling water, lime, shrub) or mix with bourbon.
Peach-honey shrub. Use ripe yellow peaches (250g, pitted and sliced) with 200g raw honey in place of sugar. Honey ferments more actively, so the wild-fermented version of this one is especially good — similar to a very young mead mixed with vinegar. Let it ferment for 4 to 5 days and taste daily. Finish with white wine vinegar rather than cider vinegar, which keeps the flavor light and summery. See our guide to fermented strawberries for a similar honey-fermentation approach.
How to Use Shrubs
The standard pour is 1 to 2 tablespoons of shrub per serving, combined with sparkling water for a simple mocktail. Adjust to taste — some shrubs are bolder and need less.
Sparkling shrub soda. 1.5 tbsp shrub + 200ml sparkling water + ice. The simplest, most refreshing option. No garnish necessary, but a slice of lemon or fresh herb never hurts.
Shrub cocktails. Most shrubs pair naturally with spirits. Strawberry-balsamic shrub with gin. Blackberry-ginger shrub with bourbon. Peach-honey shrub with rum. Use 1 to 2 tbsp shrub in place of or alongside simple syrup in your standard cocktail builds.
Salad dressing. Shrubs make excellent vinaigrettes — replace or augment the vinegar in any salad dressing recipe with 1 to 2 tablespoons of shrub. Blackberry-ginger shrub is particularly good on a grain salad with grilled chicken.
Marinade base. Shrub + olive oil + garlic + herbs makes a quick marinade for chicken, pork, or summer vegetables. The fruit sugar caramelizes nicely on the grill.
Storage and Shelf Life
Finished shrubs keep in the refrigerator for 3 to 6 months. The acidity from the vinegar acts as a preservative. There's no need to heat-process or can them. Store in a sealed glass jar or bottle.
The flavor of a shrub continues to evolve in the fridge — most reach peak integration at 1 to 2 weeks after straining. If a shrub tastes sharp or harsh on day one, try it again a week later. The edges usually smooth out significantly.
Shrubs are one of the few fermentation projects that genuinely require almost no equipment. A jar, a knife, and a strainer are all you need. If you're new to fermentation, it's one of the best places to start — low risk, immediate reward, and the results are impressive enough to make you want to make more.
