You know those drinks that make you close your eyes with the first sip and just say “mmmmm”? That’s what we’re making today, friends. My Kentucky Mule recipe came to life during an impromptu summer gathering when I ran out of vodka but had a bottle of bourbon that had been warming my bar cart for months.
What started as a happy accident turned into the signature cocktail everyone requests when they visit! The zingy ginger beer creates this incredible fizzy hug around the warm bourbon notes, while fresh lime juice cuts through with just the right amount of brightness. Last Fourth of July, my brother-in-law knocked over his copper mug reaching for seconds of potato salad, and instead of being upset about the spill, he just looked at me and said, “Worth it. Can I have another?” That’s when I knew this recipe was truly special. Trust me, after one sip of this refreshing concoction, you’ll understand why copper mugs mysteriously disappear from my kitchen after dinner parties!

Why You’ll Love This Kentucky Mule
One sip of this Kentucky Mule and you’ll feel the delightful tingle of spicy ginger beer dancing with smooth bourbon on your tongue. The copper mug turns ice-cold in your hands, creating this wonderful contrast with the warming sensation of the bourbon sliding down your throat. It’s like summertime in a cup, even in the dead of winter! When you squeeze that fresh lime wedge over the top, it releases this bright citrus aroma that makes your mouth water before you even take a drink.
What I love most is how this cocktail transitions perfectly through seasons. It’s refreshingly cool for summer barbecues but that bourbon backbone makes it cozy enough for autumn evenings on the porch. The high quality ginger beer creates the most satisfying fizz that tickles your nose with each sip. There’s something almost nostalgic about it, even if you’ve never had one before.
Grandma calls these my “company’s coming” drinks because whenever I pull out the copper mugs, everyone gathers in the kitchen with this look of anticipation. Even my husband, who normally sticks to his boring old beer, makes grabby hands when he sees me muddling lime for these babies. This isn’t just a drink. It’s a moment, an experience, a little celebration in a cup!
Ingredients for Kentucky Mule Recipe
The beauty of a Kentucky Mule is its perfect simplicity. Just three main ingredients that work together like they were always meant to be friends. Each component plays an essential role in creating that signature refreshing-yet-warming sensation that makes this drink so special.
What You’ll Need
- Bourbon whiskey (or non-alcoholic bourbon alternative)
- Ginger beer (not ginger ale)
- Fresh limes
- Ice cubes
- Copper mug
- Fresh mint sprigs (optional garnish)
Why These Ingredients Matter
The robust character of bourbon (or bourbon extract mixed with apple juice for an alcohol-free version) gives this drink its distinctive caramel warmth that standard Moscow Mules simply don’t have. I’ve found that high quality ginger beer, the spicier the better, creates the perfect counterbalance to the sweetness. Using freshly squeezed lime juice rather than bottled makes a world of difference in brightness and flavor. That copper mug isn’t just for Instagram either! It actually keeps your drink colder longer and some swear it enhances the ginger’s natural zing. Trust me, once you’ve had a properly made Kentucky Mule, you’ll understand why these specific ingredients create such magic together.

Instructions for Making Kentucky Mule
Step-by-Step Directions
- Step 1: Fill your copper mug completely with ice cubes. The more ice, the better. It helps keep everything perfectly chilled while you sip.
- Step 2: Pour 2 ounces (about 2 shots) of bourbon over the ice. If using the non-alcoholic version, use 2 ounces of your bourbon alternative.
- Step 3: Squeeze half a lime directly into the mug, about 1 tablespoon of juice. Drop the lime shell into the drink for extra flavor.
- Step 4: Top with 4-6 ounces of spicy ginger beer, pouring slowly down the side of the mug to preserve the carbonation.
- Step 5: Gently stir with a bar spoon to combine all ingredients without losing the fizz.
- Step 6: Garnish with a fresh lime wedge and mint sprig if desired.
Hint: When selecting ginger beer, look for one that lists “ginger” high up in the ingredients list. It should have a genuine spicy kick, not just sweetness. I’ve found that Fever-Tree and Bundaberg make excellent options that really make this drink shine. For best results, chill your copper mug in the freezer for about 15 minutes before mixing your Kentucky Mule!
Top Tip
The secret to a perfect Kentucky Mule is in the details! Always build in this order: bourbon first, lime juice second, ginger beer last. Pre-chill your copper mug for at least 15 minutes in the freezer before making your drink. Stir gently just 2-3 times to preserve the fizz, and give that lime garnish a final squeeze right before your first sip for an aromatic boost that makes all the difference. Temperature control is everything with this drink, so keep those ice cubes coming!
Personal Anecdote
I discovered the Kentucky Mule completely by accident during my annual Memorial Day cookout five years ago. Grandma had just arrived with her famous potato salad, and I was mixing drinks when I realized I’d run out of vodka for the Moscow Mules I’d promised everyone.
In a moment of panic, I grabbed the bottle of bourbon Grandma had given me for Christmas and decided to wing it. When I nervously served the first one to Grandma, she took one sip, looked at me with twinkling eyes, and declared, “Well Jazzy, looks like you’ve found yourself a signature drink!” The bourbon version was such a hit that three copper mugs mysteriously “walked off” with guests that night.
Now it’s become our family tradition that whenever someone brings me a bottle of bourbon or a copper mug as a gift, Grandma always chimes in with, “That’s because my Jazzy makes the best Kentucky Mules this side of Louisville!” Those missing mugs were worth every penny for the memory of that accidental discovery.
Substitutions for Kentucky Mule Recipe
Don’t have the exact ingredients? No worries! Here are some simple swaps that still make a delicious drink:
Bourbon – If you don’t have bourbon, rye whiskey works beautifully for a spicier version. For a non-alcoholic option, mix 2 oz of apple juice with a few drops of bourbon extract or vanilla extract.
Ginger Beer – In a pinch, you can use ginger ale, but add a pinch of cayenne pepper to get that signature spicy kick that makes a mule special.
Copper Mug – No copper mug? Any chilled glass will work! A highball or mason jar makes a perfect substitute while still looking cute for photos.
Lime – If fresh limes aren’t available, bottled lime juice works (about 1 tablespoon per drink), but add a lemon wedge garnish to bring back some of that fresh citrus aroma.
Mint – Skip it altogether or substitute with a thin slice of cucumber for a refreshing garnish alternative.
Variations on Kentucky Mule Recipe
Looking to switch things up? These tasty variations will keep your Kentucky Mule game fresh and exciting:
Spicy – Add 2-3 thin slices of jalapeño and muddle gently with your lime for a drink with serious kick. Perfect for those who love a little heat!
Berry Infused – Muddle 3-4 fresh blackberries or raspberries at the bottom of your mug before adding other ingredients. The berry sweetness pairs beautifully with the bourbon’s caramel notes.
Autumn Harvest – Add a splash of apple cider and a cinnamon stick garnish for a fall-inspired version that tastes like a crisp October evening.
Southern Sweet Tea – Replace half the ginger beer with unsweetened iced tea for a refreshing twist that’s perfect for lazy summer afternoons on the porch.
Smoky Mountain – Use a smoky bourbon like Elijah Craig and add a drop of liquid smoke for a campfire-inspired cocktail that’ll warm you right up on cool evenings.
Equipment for Kentucky Mule Recipe
The right tools make all the difference when crafting the perfect Kentucky Mule. While you technically can make this drink in any glass, a genuine copper mug isn’t just about looks. The metal actually conducts temperature efficiently, keeping your drink colder longer on hot summer days. I keep mine in the freezer for about 15 minutes before making drinks.
For measuring, I recommend using a proper jigger rather than eyeballing it. The balance between bourbon, lime and ginger beer is crucial, and a jigger ensures consistency every time. I use a standard 1-2 oz jigger that I picked up at a local kitchen store.
A good bar spoon with a twisted handle makes stirring efficient without disturbing too much of the carbonation in your ginger beer. If you don’t have one, a regular teaspoon works fine. Just be extra gentle when stirring.
For the freshest lime juice, a hand citrus press is worth its weight in gold. The one in my drawer has paid for itself many times over in juice yield compared to squeezing by hand. Plus, it catches the seeds so they don’t end up in your beautiful drink!

Storage Tips for Kentucky Mule Recipe
Kentucky Mules are definitely best enjoyed right after they’re made when everything is perfectly chilled and the ginger beer is at its fizziest. If you’re hosting a party though, there are ways to prep ahead to make serving quick and easy!
You can pre-slice your lime wheels and store them in an airtight container in the fridge for up to 24 hours. Just place a slightly damp paper towel over them to keep them from drying out. For lime juice, you can squeeze it fresh up to 12 hours ahead and store in a small sealed container. The flavor isn’t quite as bright as just-squeezed, but it’s still leagues better than bottled.
If you’re making a big batch for a gathering, I recommend creating a “Kentucky Mule Kit” instead of premixing everything. Set out pre-measured bourbon portions in small glasses, a pitcher of fresh lime juice, and unopened ginger beer so guests can build their own. This way the ginger beer stays fizzy and nothing gets watered down.
For non-alcoholic versions, your apple juice and extract mixture can be prepared up to 2 days ahead and stored in the refrigerator in a sealed container.

Grandma’s Secret for Kentucky Mule Recipe
Grandma isn’t much of a drinker. Her poison of choice is usually sweet tea with lemon. But she surprised everyone last Thanksgiving when she took over my Kentucky Mule station and started adding her own special touch. “Jazzy, you’re making it all wrong,” she whispered with that mischievous smile of hers.
I watched in amazement as she pulled a small jar of crystallized ginger from her purse (yes, she apparently carries emergency ginger supplies!) and placed a small piece in each copper mug before adding any liquid. “The trick isn’t just what you put in the drink,” she told me, crushing a cardamom pod between her fingers and dropping it in as well, “it’s how you layer the flavors.”
When I took that first sip, I nearly fell over. It was incredible! The subtle warmth of the cardamom and the extra ginger kick transformed my regular recipe into something truly special. When I asked why she never told me this secret before, she just patted my hand and said, “Some lessons you need to be ready for, honey. Cocktails are like life. Sometimes you need to muddle through a few bitter moments to appreciate the sweet ones.” Now I keep a little jar of “Grandma’s secret weapon” ready whenever I’m making Kentucky Mules for special occasions.
Speaking of Grandma’s specialties, her influence on my Almond Poppy Seed Muffins recipe shows her knack for adding unexpected flavors that completely transform familiar favorites.
FAQ about Kentucky Mule Recipe
What is a Kentucky Mule made of?
A Kentucky Mule contains three main ingredients: bourbon whiskey, ginger beer, and fresh lime juice. It’s served over ice in a copper mug, typically garnished with a lime wedge and sometimes mint. Think of it as the bourbon-loving cousin of the classic Moscow Mule.
What’s the difference between a Moscow Mule and a Kentucky Mule?
The only difference is the base spirit! A Moscow Mule uses vodka, while a Kentucky Mule substitutes bourbon whiskey. This simple switch adds warm caramel and vanilla notes that complement the spicy ginger beer beautifully.
What whiskey is best for a Kentucky Mule?
A mid-range bourbon works perfectly! I’ve had great results with Maker’s Mark, Buffalo Trace, and Woodford Reserve. You want something smooth with caramel notes, but don’t waste your top-shelf sipping bourbon here. The ginger beer will mask its subtleties.
What is a ginger ale and bourbon drink called?
That’s typically called a Bourbon Buck or sometimes a Horse’s Neck (especially when garnished with a long lemon peel). A Kentucky Mule specifically calls for ginger beer, which is spicier and less sweet than ginger ale.

Ingredients

- 1 sprig fresh mint Optional garnish
- 1 piece crystallized ginger Grandma's secret ingredient, optional but recommended
Instructions
- Pre-chill your [copper mug] in the freezer for about 15 minutes. Grandma always said, 'A proper mule starts with a properly cold mug!' I can still see her rearranging the freezer to make room for her favorite copper mugs before company arrived.

- Garnish with a fresh [lime] wedge and [fresh mint] sprig if desired. Grandma would tuck the mint just so, saying 'We eat with our eyes first, even with drinks,' as she positioned everything perfectly.
