- Avoid common pitfalls like over‑dilution, improper ice, and forgetting to chill the glass.
What is a Cocktail?
Cocktail is a mixed drink that combines a spirit with other ingredients such as fruit juice, sugar, bitters, or soda to create a balanced flavor profile. The word traces back to the early 19thcentury, but the modern concept of a cocktail grew out of the Prohibition era when bartenders experimented with limited supplies. Today, a cocktail is more than just a drink; it’s a tiny, portable experience that can showcase a spirit’s character, a bartender’s skill, or a cultural tradition.
The Five Basic Cocktails
If you can make these five drinks with confidence, you’ve covered the essential techniques and flavor families required to handle almost any recipe you’ll encounter.
1. The Martini
Martini is a classic, spirit‑forward cocktail that traditionally blends gin and dry vermouth, finished with an olive or lemon twist. The ratio varies-some prefer a very dry 6:1 gin‑to‑vermouth, while others enjoy an “up‑side‑down” 1:1 mix. The key steps are simple: chill a mixing glass, add gin and vermouth, stir for about 30 seconds, then strain into a chilled coupe. Garnish with a green olive or a zest‑expressed lemon peel.
- Base spirit: Gin (or vodka for a Vodka Martini)
- Key mixers: Dry vermouth
- Garnish: Olive or lemon twist
2. Old Fashioned
Old Fashioned is a foundational whiskey cocktail that combines bourbon or rye with sugar, bitters, and a citrus garnish. Build the drink directly in an Old Fashioned glass: muddle a sugar cube (or ½tsp simple syrup) with two dashes of Angostura bitters, add a large ice cube, pour 2oz of bourbon, stir gently, then garnish with an orange peel and a cherry if you like.
- Base spirit: Bourbon or rye whiskey
- Key mixers: Sugar (or simple syrup) and bitters
- Garnish: Orange peel, optional cherry
3. Margarita
Margarita is a refreshing tequila‑based cocktail that balances lime juice, orange liqueur, and a salted rim. Shake 2oz tequila, 1oz Cointreau (or triple sec), and 1oz fresh lime juice with ice. Strain into a glass rimmed with coarse salt-serve on the rocks or straight up in a coupe. A slice of lime adds a visual cue and an extra burst of aroma.
- Base spirit: Tequila (blanco or reposado)
- Key mixers: Lime juice and orange liqueur
- Garnish: Salted rim and lime wedge
4. Mojito
Mojito is a Cuban classic that pairs white rum with fresh mint, lime, simple syrup, and club soda for a light, effervescent sip. Muddle 6-8 mint leaves with ½oz simple syrup and the juice of half a lime. Add 2oz white rum, fill the glass with crushed ice, top with soda water, and stir gently. Finish with a mint sprig and a lime wheel.
- Base spirit: White rum
- Key mixers: Mint, lime juice, simple syrup, soda water
- Garnish: Mint sprig and lime wheel
5. Daiquiri
Daiquiri is a simple, shaken cocktail that highlights rum, lime juice, and a touch of sugar for a perfectly balanced sour. Combine 2oz white rum, 1oz fresh lime juice, and ½oz simple syrup in a shaker, add ice, and shake hard for 10‑12 seconds. Strain into a chilled coupe; a lime twist optional.
- Base spirit: White rum
- Key mixers: Lime juice and simple syrup
- Garnish: Lime twist (optional)

Daiquiri | White Rum | Lime Juice & Simple Syrup | Coupe | Lime Twist (optional) |
Essential Tools & Glassware
Even the simplest cocktail looks better (and tastes better) when served in the right vessel. Here’s a short checklist of must‑have bar tools:
- Shaker (Boston or Cobbler): For shaken drinks like the Margarita, Mojito, and Daiquiri.
- Mixing glass: Ideal for stirred drinks such as the Martini and Old Fashioned.
- Jigger (1oz / ½oz): Guarantees consistent pours.
- Bar spoon: Perfect for gentle stirring and layering.
- Muddler: Essential for releasing mint oils in a Mojito.
- Fine‑strainer: Removes ice shards from shaken cocktails.
Choose glassware that matches the drink’s style: a coupe for elegance, an Old Fashioned glass for spirit‑forward sips, and a highball for refreshing, soda‑based drinks.
Techniques that Make or Break a Cocktail
Mastering a handful of techniques will keep your drinks consistently good.
- Stirring vs. Shaking: Stir when you want a silky, clear texture (Martini, Old Fashioned). Shake when you need dilution, chilling, and aeration (Margarita, Daiquiri, Mojito).
- Ice Management: Use large, clear cubes for stirring; crushed ice for Mojitos; fresh ice for shaking to avoid over‑dilution.
- Muddling: Press, don’t crush, when releasing herbs. Over‑muddling releases bitter chlorophyll.
- Straining: Fine‑strain shaken drinks to catch tiny ice shards; double‑strain if you’ve used fruit pulp.
- Chilling the Glass: Pop the serving glass in the freezer for 5minutes or fill with ice water while you prep.

Common Mistakes and How to Fix Them
- Too much dilution: Keep shaking time to 10‑12 seconds; use a metal shaker that stays cold.
- Wrong garnish: Garnish isn’t decorative only; it adds aroma. Use fresh citrus and quality olives.
- Using bottled lime juice: Fresh juice provides bright acidity that bottled versions lack.
- Skipping the sugar balance: A cocktail is a balance of sweet, sour, bitter, and spirit. Taste before you serve and tweak with a dash of simple syrup.
- Improper ice: Tiny or cloudy ice melts fast and waters down the drink. Invest in a good ice maker or freeze filtered water in large molds.
Where to Go From Here
Now that you’ve nailed the five core drinks, experiment with variations. Swap gin for vodka in a Martini, try a smoky mezcal Margarita, or add fresh berries to a Mojito. The principles you’ve learned-balance, technique, and proper tools-apply to every new recipe you try.
Frequently Asked Questions
Can I use bottled lime juice for a Margarita?
Fresh lime juice is strongly recommended because it provides a brighter, cleaner acidity. Bottled juice can taste flat and may contain preservatives that affect the cocktail’s flavor.
What’s the difference between a dry and a wet Martini?
A dry Martini uses less vermouth-often a 6:1 or higher gin‑to‑vermouth ratio-while a wet Martini has a richer vermouth presence, typically around 2:1. Choose based on how pronounced you want the vermouth flavor.
Should I stir an Old Fashioned or shake it?
Stirring is the traditional method. It gently dilutes and chills the drink while keeping the spirit’s texture smooth. Shaking would over‑dilute and create a cloudy appearance.
Can I make a Mojito without fresh mint?
Fresh mint is key for the classic aroma and flavor. If you’re out of mint, you can try a flavored simple syrup (e.g., basil or cucumber) but the drink will no longer be a true Mojito.
Is a Daiquiri the same as a frozen blended drink?
No. The classic Daiquiri is a shaken, clear cocktail served straight up. Frozen versions add ice and become a slushy, which is a different style altogether.
