Capers & Cocktails: How to Make a Caperberry Martini (Using Syrups and Shrubs)

Hook: Stop staring at jars of capers wondering how to use them in cocktails

If you love briny, savory flavors but feel stuck using capers only on pasta and salads, you’re not alone. Home bartenders and restaurant mixologists in 2026 are turning caperberries and caper-infused syrups into the next wave of savory cocktails—and this guide gives you the exact syrups, shrubs, martini recipes, and pairing ideas to make bar-quality drinks at home.

Why read this now?

Recent craft-cocktail developments (late 2025–early 2026) show a surge in vinegar-based modifiers and non-alcoholic syrups, and bars are scaling small-batch creations into DTC offerings. This article gives you practical recipes, shopping and storage tips, plating ideas, and advanced mixology tricks so you can make a caperberry martini that tastes intentional—not experimental.

Quick takeaways

• Caperberry syrup is sweet, briny, and floral—use 0.25–0.75 oz per cocktail depending on sweetness.
• Caper shrub (vinegar-based) adds brightness and savory acid—use for dirtier, more complex martinis.
• Skewer a caperberry as garnish for aroma and visual impact; reserve brine for subtle saltiness.
• Pair caperberry martinis with smoked fish, grilled vegetables, and quick open-faced sandwiches for a restaurant-grade experience.

The evolution of capers in cocktails (2026)

Through 2025 and into 2026, craft syrup makers pushed beyond citrus and sugar by embracing savory modifiers—olives, anchovy-infused syrups, and now caperberries. One well-known example: a small-batch company that started on a single stove pot grew into 1,500-gallon production tanks while keeping that experimental, DIY spirit alive.

“It all started with a single pot on a stove.” — a founder in the craft syrup movement

This DIY-to-scale arc matters: it means you can buy thoughtfully made caper syrups or easily make your own with home equipment. The bar trend is simple—mixologists want versatile, shelf-stable modifiers that deliver acidity, sweetness, and savory complexity in one measure. Caperberries and shrubs fit that bill.

Why caperberries and caper syrups work in cocktails

Caperberries (the fruit of the caper bush) are larger and meatier than caper buds, with a juicy center and a pleasant latex-like texture. They bring:

• Briny umami that amplifies savory notes in spirits
• Floral and citrusy aromatics when macerated into syrups
• Acidity potential when paired with vinegar in shrubs

Use caperberry syrup for a sweet-briny modifier and caper shrub when you want sharp, vinegar-driven brightness. Both are perfect in martini templates and beyond.

How to make caperberry syrup (caper-infused simple syrup)

This is the fastest path from pantry to glass. Syrups are shelf-stable for weeks when refrigerated and pasteurized, and they add controlled sweetness plus aromatic brine.

Basic caperberry syrup (makes ~2 cups)

• Ingredients: 1 cup water, 1 cup granulated sugar, 1/2 cup chopped caperberries (reserve some whole for garnish), 1 tbsp caper brine (optional), 1 strip lemon zest
• Equipment: small saucepan, fine mesh strainer, clean jar, funnel

Method:

1. Combine water and sugar in saucepan over medium heat; stir until sugar dissolves.
2. Add chopped caperberries, lemon zest, and caper brine. Simmer gently for 8–10 minutes.
3. Remove from heat and steep 20–30 minutes off the stove to allow aromatics to marry.
4. Strain through a fine mesh into a sterilized jar; press solids lightly to extract liquid.
5. Cool, then refrigerate. Optionally, pasteurize by simmering the strained syrup 2 minutes and bottling hot—this extends shelf life to 4–6 weeks refrigerated.

Variation: substitute half the sugar for honey at step 1 for a richer mouthfeel; reduce simmer time to preserve floral notes.

How to make a caper shrub (caperberry vinegar tonic)

Shrubs are vinegar-based and rose as a major cocktail trend in 2025–26. They contribute acid, savory complexity, and long shelf life. Use them sparingly—start with 0.25–0.5 oz in cocktails.

Basic caperberry shrub (makes ~1 pint)

• Ingredients: 1 cup chopped caperberries, 1 cup sugar, 1 cup white wine vinegar (or apple cider vinegar for fruitier notes), 2 tbsp leftover caper brine

Method:

1. Muddle caperberries with sugar in a jar until juices release. Let sit at room temp 2–4 hours or refrigerate overnight.
2. Add vinegar and caper brine, stir to dissolve sugar. Seal and refrigerate for 3–7 days, shaking daily.
3. Strain and bottle. Shrub will keep refrigerated for 2–3 months; if you taste any off aromas, discard.

Tip: use a 1:1:1 ratio (fruit:sugar:vinegar) as a starting point. For a less sweet shrub, reduce sugar to 3/4 cup. For a sharper shrub, use sherry or white balsamic vinegar.

Core recipes: The Caperberry Martini series

Below are four martini templates—classic, dirty, zero-proof, and a bolder botanical option. All recipes assume 2 oz base spirit (or non-alc substitute), and use chilled glassware.

1) Classic Caperberry Martini (garnish-forward)

• Ingredients: 2 oz gin (London Dry), 0.5 oz dry vermouth, 0.5 oz caperberry syrup, dash orange bitters (optional)
• Method: Stir ingredients with ice (30–45 seconds) and strain into a chilled martini glass. Garnish with 2 skewered caperberries and a lemon twist.
• Taste: bright, slightly sweet, with a floral-briny finish. Use syrup to control sweetness and aroma.

2) Dirty Caperberry Martini (vinegar-accented)

• Ingredients: 2.25 oz vodka, 0.5 oz dry vermouth, 0.25 oz caper shrub, 0.25 oz reserved caper brine (adjust to taste)
• Method: Stir with ice and double-strain into chilled coupe. Garnish with a caperberry and a strip of pickled cucumber.
• Taste: savory, bracing acid, perfect with richer appetizers.

3) Zero-Proof Caperberry Martini (non-alcoholic)

• Ingredients: 2 oz non-alc gin alternative (botanical), 0.5 oz caperberry syrup, 0.25 oz caper shrub, 0.25 oz lemon juice
• Method: Shake with ice, double-strain, and serve in a chilled martini glass. Garnish with a micro-herb and one caperberry.
• Taste: balanced and satisfying as a non-alcoholic option—shrubs are particularly useful in zero-proof drinks.

4) Caper & Herb Botanical Martini (for gin lovers)

• Ingredients: 2 oz herbaceous gin, 0.25 oz dry vermouth, 0.5 oz caperberry syrup, 0.25 oz rosemary-caper shrub (optional)
• Method: Stir and garnish with a sprig of rosemary and a caperberry. For extra aroma, flame the rosemary briefly over the glass rim (advanced).

Advanced mixology tips & techniques

Small changes make big differences with briny modifiers.

• Balance salt vs. sweet: If your martini tastes too salty, add a touch more vermouth or 0.25 oz simple syrup. If too sweet, add 2–3 drops of lemon juice or more shrub.
• Dilution matters: Briny flavors concentrate quickly—stir longer to open the drink and mellow intensity. For shaken recipes, use fresh big ice to reduce harshness.
• Layer aromatics: Garnish caperberries but also add an express of lemon oil over the drink to brighten the top note.
• Infusing base spirits: Make a quick caper-infused gin by adding 1 tbsp chopped caperberries to 16 oz gin for 12–24 hours, then filter. Use as a substitute for standard gin in the recipes above.
• Clarity: If you want a crystal-clear martini, use clarified syrup (cold crash and filter through coffee filter) or fine-double strain to remove solids.

Pairings, quick meals, and plating ideas

Caperberry martinis pair beautifully with dishes that mirror their salt-umami profile. Here are quick, restaurant-worthy pairings you can plate at home.

Small plates

• Smoked trout crostini with crème fraîche and a single caperberry on top.
• Tuna tartare with yuzu, sesame, and minced caperberries—serve in small spoons.
• Grilled sardine toast: char bread, oil, grilled sardine, lemon, and caperberry chop.

Vegetarian options

• Charred asparagus with lemon aioli and halved caperberries.
• Warm burrata with preserved lemon, olive oil, and capers with torn basil.

Plating tips

• Serve caperberry martinis with a small plate of the same bright herb or citrus used in the garnish to echo aromatics.
• Skewer 2–3 caperberries with a sprig of thyme for a refined look and layered aroma.
• Use narrow cocktail plates for crostini to keep the focus on the glass and garnish.

Sourcing, provenance, quality grades, and storage

When shopping, look for sellers who list region and packing solution. In 2026, buyers prefer transparency: growers in Sicily, Greece, and Turkey often market single-origin capers and caperberries.

• Quality picks: larger caperberries (capote) for garnish; nonpareil capers for cooking. For cocktails, choose brined caperberries packed in vinegar or wine for better aromatic range.
• Packaging: glass jars preserve aroma; look for nitrogen-flushed or brine-packed jars when buying online to ensure long shipping life.
• Storage: Refrigerate opened jars. Syrups last 4–6 weeks refrigerated (pasteurized) and shrubs 2–3 months. Label jars with date made.

Note on shipping: fragile glass jars and brines require secure packaging—DTC syrup brands expanded their insulated, returnable packaging options in late 2025 to reduce breakage and waste.

Troubleshooting common issues

• Too salty: dilute with extra spirit or a small splash of water, use less reserved brine next time.
• Overly sweet syrup: balance with 0.25–0.5 oz caper shrub or a squeeze of lemon.
• Cloudy syrup: filter through coffee filter; if off-odors develop, discard.
• Weak caper flavor: increase infusion time (syrup) or steep shrub longer (up to 7 days).

Trends & future predictions for 2026

Expect these moves through the rest of 2026:

• Savory modifiers mainstreaming: caper and anchovy syrups appearing on cocktail menus in gastropubs and tasting rooms.
• Zero-proof innovation: shrubs and caper syrups powering non-alcoholic cocktails that truly satisfy umami cravings.
• Local micro-production: more bars making on-site caper shrubs and syrups to reduce waste and tailor flavor profiles.
• Sustainable packaging: refillable syrup pouches and concentrated syrups to reduce shipping weight and carbon footprint.

Experience, expertise, and real-world case study

From an industry perspective, small teams that started hand-crafting syrups at home have scaled while preserving artisanal techniques. That DIY lineage—test small, iterate flavors, then scale—means the home bartender can replicate those methods in their kitchen. Try the syrup and shrub recipes above, then adjust the spice and acid to match your region’s palate.

Actionable checklist before you shake

• Chill your glass and set out garnish (capperberries, citrus twist, herbs).
• Make syrup/shrub 24–48 hours ahead for best marrying of flavors.
• Taste and adjust brine level with small increments—0.1 oz matters.
• Label and date homemade syrups to track freshness.

Final serving suggestions and plating for gatherings

When serving a flight of caperberry martinis, present three tiny spoons with matching bites: smoked fish, charred asparagus, and a small cheese square topped with one caperberry. This creates a curated experience where each sip echoes the small plates.
