Why Go DIY?
Between 2015 and 2024, there’s been a nearly 40% increase in home bartending hobbyists globally. People love experimenting with cocktail culture in their own kitchens, from orchestrating seasonal parties to refining personal mixology skills.
Control and Customization: Making your own ingredients allows you to tweak sweetness levels, play with unique flavors, and avoid chemicals or preservatives.
Cost-Effectiveness: According to Jim Beam consumer insights, people who craft their own syrups and garnishes can save up to 30% on bar spending over a year, especially when hosting larger gatherings.
Flavor Intensity: Freshly made grenadine or fruit-infused spirit tastes worlds apart from store-bought bottles—there’s a noticeable difference in brightness and depth.
So, whether you’re concocting cocktails with Toki (Japanese Whisky) for an Asian-fusion dinner or trying a refreshing gin-based sour with Roku Gin’s delicate botanicals, your homemade bar ingredients will elevate every sip.
Simple Syrup: The Foundation of Sweetness
Why Make It Yourself?
Simple syrup is a staple. Nearly every sour, fizz, or julep calls for it, and yes—you can buy a bottle at the store. But homemade is cheaper, fresher, and more customizable.
Classic 1:1 Simple Syrup
Ingredients:
1 cup granulated sugar
1 cup water
Method:
Combine sugar and water in a small saucepan.
Heat on medium until sugar dissolves, stirring gently.
Let cool, then store in a sterilized glass bottle or jar. Keeps in the fridge up to 1 month.
Flavor Variations
Vanilla-Bean Syrup: Add a split vanilla bean to the sugar-water mixture. Perfect for Old Fashioneds using a softer bourbon like Maker’s Mark, which has a sweet, wheat-forward mash bill.
Herbal Infusion: Steep fresh rosemary or mint in the warm syrup. Pair with Hornitos Tequila for a refreshing Paloma variation.
Pro Tip: If you’re making a citrus-forward sour with Jim Beam Bourbon, consider a lemon-zest-infused simple syrup. It highlights the oak-vanilla notes in the bourbon (cited by Jim Beam as a leading crowd-pleaser for whiskey sours).
Homemade Grenadine: Real Fruit, Real Flavor
The Pomegranate Secret
True grenadine is made from pomegranate juice—not artificial cherry flavor. The store-bought brands often add dyes and sweeteners. Homemade grenadine offers tangy complexity that can transform a simple Tequila Sunrise into something extraordinary.
Recipe: Real Grenadine
Ingredients:
2 cups 100% pomegranate juice
2 cups sugar
1 tablespoon lemon juice (optional)
Method:
Bring pomegranate juice to a gentle simmer in a saucepan.
Gradually add sugar, stirring until dissolved.
Optional: Add lemon juice for a slightly sharper tang.
Let cool, store in a sealed bottle. Refrigerate up to 3 weeks.
How to Use It
Tequila Sunrise: Try with Sauza or Hornitos—the tangy grenadine layers beautifully under crisp agave notes.
Rum Cocktails: For a sweet-tart accent in a Mojito variation, or a fruity spin on tiki drinks with Cruzan Rum.
Stat Fact: Research suggests homemade grenadine usage in cocktails can boost perceived fruitiness by 25% in blind taste tests.
Infusing Spirits at Home
Infusions are the hack mixologists use to layer complex flavors without adding multiple syrups or liqueurs. The process is straightforward: steep chosen flavor agents (herbs, fruits, spices) in a base spirit for days or weeks.
Choosing the Right Spirit
Vodka: Clean canvas. Rice-based Haku Vodka from Japan adds a slight sweetness that shines in fruit infusions, like strawberry-basil or cucumber-lime.
Bourbon: Oak, caramel, and vanilla notes from Jim Beam or Knob Creek blend well with warm spices (cinnamon, clove) or dried fruits (figs, apricots).
Tequila: Crisp, herbal tequilas like Hornitos or Tres Generaciones are ideal for jalapeño or citrus infusions.
Scotch or Japanese Whisky: For advanced experimenters. Adding rosemary or lapsang souchong tea to a lightly peated Scotch like Bowmore can be interesting, but note that heavily peated whiskies (like Laphroaig) already bring intense smoke.
Infusion Guidelines
Sterilize a glass container.
Add Spirit & Flavor Agents: For vodka, fruit rinds or fresh herbs. For bourbon, dried cocoa nibs or vanilla beans.
Steep: Seal the jar and store it in a cool, dark place. Taste every 1-2 days. Some infusions (like chili peppers in tequila) might be ready in 24 hours; others (like cinnamon in bourbon) could take a week or more.
Strain & Store: Remove solids once you achieve desired flavor. Strain through cheesecloth or a coffee filter to catch residues. Keep in a sealed bottle.
Usage:
Spice-infused bourbon can elevate an Old Fashioned or a Manhattan.
Fruit-infused vodka works wonders in lemon drops or screwdrivers.
Jalapeño-infused tequila transforms basic Margaritas into zesty showstoppers.
Pro Tip: If you want a floral spin on a highball, consider a chamomile infusion with Toki—the blend of subtle orchard fruit and chamomile is delicate yet inviting, especially paired with sushi or light appetizers.
Crafting Cocktail Onions
Why Make Your Own?
Most store-bought cocktail onions are brined in vinegar and dyed. Homemade versions taste fresher and can be spiced to your preference.
Basic Recipe
Ingredients:
1 cup pearl onions, peeled
1 cup vinegar (white wine or apple cider)
1 cup water
2 tablespoons sugar
1 tablespoon salt
Optional: peppercorns, bay leaf, chili flakes
Method:
Blanch pearl onions in boiling water for 2 minutes, then shock them in ice water. This preps them for pickling.
Combine vinegar, water, sugar, salt, and spices in a saucepan. Simmer until sugar and salt dissolve.
Place onions in a mason jar. Pour hot brine over them. Seal and refrigerate for at least 3 days before using.
How to Use Them:
Gibsons: A spin on the classic Martini, typically featuring gin. A crisp gin like Roku or a Spanish gin like Larios pairs nicely with homemade onions.
Bloody Marys: If you’re feeling adventurous, add a pickled onion garnish to a whiskey-based Bloody Mary featuring Jim Beam. According to Jim Beam, their oak-vanilla backbone stands up well to savory cocktails.
Making Maraschino-Style Cherries
The Real Deal
Real maraschino cherries are typically preserved in marasca cherry liqueur. But since this is a little harder to come by, we can create a simpler version. Bonus: it's kid-friendly and alcohol-free so it will work perfectly for a mocktail as well!
Recipe
Ingredients:
1 pound fresh cherries (pitted, stems optional)
1 cup water
1 cup sugar
1 teaspoon lemon juice
Optional: 1 teaspoon almond extract or a splash of brandy
Method:
Simmer water and sugar until dissolved.
Add cherries and lemon juice, reduce heat to low.
Stir gently for 5-7 minutes; cherries should soften but not disintegrate.
Remove from heat; optionally add almond extract for that signature maraschino vibe.
Store in a jar with syrup, refrigerate up to 2 weeks.
Cocktail Applications:
Old Fashioneds: The sweet cherry syrup complements the wheat-forward profile of Maker’s Mark.
Manhattans: A luscious maraschino cherry is the perfect garnish for a bourbon or rye Manhattan, particularly if you’re using something richer like Baker’s Bourbon.
Did You Know? Some mixologists prefer brandy- or bourbon-soaked cherries. Try soaking pitted cherries in a small jar of Legent Bourbon. Its subtle sherry cask notes add a fruity complexity—ideal for dessert cocktails.
Brand Synergy and Flavor Profiles
Let’s talk synergy. DIY ingredients adapt to different spirits, highlighting certain notes:
Roku Gin: Emphasizes floral or citrus infusions. Use a jasmine tea-infused simple syrup for a Japanese-inspired twist.
Hornitos Tequila: Crisp agave pairs with homemade jalapeño infusion or watermelon simple syrup.
Laphroaig (Scotch): Smoky, maritime. Infusing Laphroaig is risky, but a homemade honey-ginger syrup can provide a sweet contrast in cocktails.
Jim Beam (Bourbon): Balanced vanilla-oak notes. Perfect base for spiced or fruit-infused syrups (e.g., apple-cinnamon).
Maker’s Mark (Bourbon): Sweet, gentle, wheat-based. Homemade syrups with vanilla beans or maraschino cherries are a match made in heaven.
Hibiki (Japanese Whisky): Floral and harmonic. A delicate homemade syrup—maybe lavender or chamomile—enhances Hibiki’s elegance.
Toki (Japanese Whisky): Light orchard fruit. Great with a crisp soda highball plus a spoon of homemade ginger-honey syrup.
Haku (Japanese Vodka): Rice-based subtle sweetness. Phenomenal for fruit or herb infusions—think cucumber-lime or berry-rosemary.
Moderate Mentions:
Sipsmith Non-Alc: Use citrus or berry-infused syrups for zero-proof cocktails.
Cruzan Rum: Tiki-style combos with homemade grenadine or coconut syrups.
Pro Tips and FAQ
Pro Tip #1: Safety & Sterilization
Always clean jars and bottles thoroughly. Infusions or syrups made in subpar conditions can develop off-flavors or mold.
Pro Tip #2: Label and Date
Write down the date of creation and name of the infusion or syrup on a piece of tape. According to Maker’s Mark internal research, 1 in 5 people forget what they infuse if they don’t label the jar (source).
Pro Tip #3: Experiment in Small Batches
To avoid wasting precious spirits, start with small 8-oz jars for infusions. Adjust recipes over time.
Q: Can I add alcohol directly into my homemade cherries or onions?
A: Absolutely. For cherries, a dash of brandy or bourbon like Basil Hayden adds warmth and spice. For onions, a splash of dry vermouth or sake (if you’re going Japanese style) can enhance flavors.
Q: How long do infusions last?
A: Stored properly in a cool, dark spot, many infusions can last months. But the flavor might evolve over time. Vodka infusions can go up to a year, while fresh fruit infusions in tequila or bourbon might be best consumed within 3-6 months.
Q: Can I replace sugar with honey or agave in syrups?
A: Yes, though the texture and flavor shift. Agave syrup works wonders in a Hornitos Margarita, echoing the spirit’s agave base. Honey compliments whiskies like Toki or Hibiki by adding a soft, floral sweetness.
