What to check first

This isn’t about brewing coffee, but we’re using its core elements. So, a quick check on your ingredients is key for the best outcome.

Bourbon Quality

This is your foundation. You don’t need the rarest bottle, but avoid anything you wouldn’t sip on its own. A decent mid-shelf bourbon will give you a clean canvas. Think about what tasting notes you like in bourbon – oak, vanilla, caramel? This will influence how the coffee interacts.

Coffee Bean Freshness

This is crucial. You want whole beans, not pre-ground stuff. Freshly roasted beans have the most vibrant oils and aromas. Look for a roast date on the bag. Ideally, beans roasted within the last few weeks are best. Avoid stale beans; they’ll just give you a dull, muted flavor.

Equipment Cleanliness

Since we’re not heating anything, a boiling water rinse isn’t as critical as with a coffee brewer. However, your infusion vessel needs to be spotless. A mason jar is perfect. Just make sure it’s washed thoroughly with hot, soapy water and rinsed well. Any lingering smells or residues will mess with your bourbon.

Step-by-step (how to make coffee infused bourbon)

This is pretty straightforward. It’s more about patience than complex technique.

1. Gather your bourbon. Pick a bourbon you enjoy drinking neat. A 750ml bottle is a good starting point.

• What “good” looks like: A clear, pleasant-smelling spirit ready to accept new flavors.
• Common mistake: Using a cheap, harsh bourbon. This will only amplify its bad qualities.
• Avoid it by: Choosing a bourbon you’d happily sip before you start infusing.

2. Select your coffee beans. Go for whole, fresh beans. A medium to dark roast often works well, but lighter roasts can bring interesting fruity or floral notes.

• What “good” looks like: Whole, fragrant beans with visible oils (if it’s a darker roast).
• Common mistake: Using old, stale beans or pre-ground coffee.
• Avoid it by: Checking the roast date and ensuring the beans are whole.

3. Measure your beans. A good starting point is a 1:1 ratio by volume. For a 750ml bottle of bourbon, try about 1 cup of whole beans. You can adjust this later.

• What “good” looks like: A measured amount of beans that feels right for the volume of bourbon.
• Common mistake: Using way too many beans, which can lead to over-extraction and bitterness.
• Avoid it by: Starting conservatively. You can always add more beans if needed.

4. Add beans to your vessel. Pour the measured whole beans into your clean mason jar or airtight container.

• What “good” looks like: All beans safely inside the jar.
• Common mistake: Spilling beans on the counter.
• Avoid it by: Pouring carefully over the open jar.

5. Pour in the bourbon. Slowly pour the bourbon over the coffee beans, ensuring they are fully submerged.

• What “good” looks like: All beans are covered by bourbon. No dry spots.
• Common mistake: Not submerging all the beans. The ones sticking out won’t infuse properly.
• Avoid it by: Tilting the jar slightly as you pour to ensure full coverage.

6. Seal the vessel. Cap the jar tightly.

• What “good” looks like: A secure seal that prevents evaporation.
• Common mistake: Leaving the lid loose.
• Avoid it by: Making sure the lid is screwed on firmly.

7. Infuse in a cool, dark place. Let the jar sit undisturbed at room temperature, away from direct sunlight.

• What “good” looks like: A stable environment where the magic can happen without interference.
• Common mistake: Storing it on a sunny windowsill or near a heat source.
• Avoid it by: Finding a pantry shelf or cupboard.

8. Start tasting. After about 24 hours, open the jar and carefully taste a small amount. Use a clean spoon or pipette.

• What “good” looks like: A noticeable coffee aroma and flavor beginning to emerge in the bourbon.
• Common mistake: Waiting too long to taste and over-infusing.
• Avoid it by: Tasting early and often.

9. Continue infusing and tasting. Taste every 8-12 hours until the flavor is to your liking. This usually takes 24-48 hours, but can vary.

• What “good” looks like: A balanced coffee flavor that complements, not overpowers, the bourbon.
• Common mistake: Infusing for too long, resulting in bitter, muddy flavors.
• Avoid it by: Stopping the infusion when it hits your sweet spot. Remember, you can always add more beans later if it’s too weak.

10. Strain the bourbon. Once satisfied, carefully strain the infused bourbon through a fine-mesh sieve lined with cheesecloth or a coffee filter. You want to remove all bean sediment.

• What “good” looks like: Crystal clear bourbon with no visible bean particles.
• Common mistake: Not straining thoroughly, leaving gritty bits.
• Avoid it by: Using multiple layers of cheesecloth or a fresh coffee filter for a super-clean result.

11. Bottle and store. Pour the strained, coffee-infused bourbon into a clean bottle. Seal it and store it in a cool, dark place.

• What “good” looks like: A beautifully infused spirit ready for enjoyment.
• Common mistake: Storing it improperly, leading to degradation.
• Avoid it by: Treating it like any other fine spirit – cool, dark, and sealed.

Common mistakes (and what happens if you ignore them)

Mistake	What it causes	Fix
Using stale or old coffee beans	Dull, flat, or papery flavor; lack of aroma.	Use fresh, whole beans with a recent roast date.
Using pre-ground coffee	Over-extraction, bitterness, and sediment.	Always use whole beans and grind them right before brewing if you were actually brewing coffee.
Using too many beans	Overpowering bitterness, astringency, muddiness.	Start with a conservative amount (e.g., 1 cup per 750ml) and adjust up if needed.
Infusing for too long	Bitter, burnt, or acrid taste; loss of bourbon character.	Taste frequently after 24 hours. Stop when the flavor is balanced.
Not straining thoroughly	Gritty texture, sediment in your drink.	Use fine-mesh sieves, cheesecloth, or coffee filters for a clean pour.
Using cheap/harsh bourbon	Amplifies unpleasant notes in the bourbon.	Choose a bourbon you enjoy drinking on its own.
Storing in direct sunlight	Degrades flavor and color over time.	Keep in a cool, dark place like a pantry or liquor cabinet.
Not submerging all beans	Uneven infusion; some beans don’t contribute flavor.	Ensure all beans are fully covered by bourbon when you seal the jar.
Using a dirty infusion vessel	Off-flavors, unwanted aromas.	Wash your jar thoroughly with hot, soapy water and rinse well.

Decision rules (simple if/then)

• If the bourbon tastes too weak after 48 hours, then add a few more whole beans and infuse for another 12-24 hours because you can always add more flavor.
• If the bourbon tastes too bitter, then strain it immediately and consider diluting it with a bit of un-infused bourbon because over-extraction is hard to reverse.
• If you want a bolder coffee flavor, then use a darker roasted bean or a bolder bourbon because different ingredients have different flavor profiles.
• If you’re making cocktails, then consider a medium roast bean because it offers a good balance that won’t clash with other ingredients.
• If you want a smoother finish, then try a lighter roast bean or a bourbon with sweeter notes (like vanilla or caramel) because these can complement the coffee’s natural bitterness.
• If you notice sediment after straining, then strain it again through a coffee filter because fine particles can ruin the texture.
• If you’re unsure about the infusion time, then err on the side of caution and taste more frequently because it’s easier to add time than to remove bitterness.
• If the aroma is overpowering, then it might be time to strain because strong aromas can sometimes indicate over-extraction.
• If you want to experiment, then try infusing with just a few beans first to gauge their impact because it’s a low-risk way to test new ideas.
• If you’re storing for a long time, then ensure the seal is absolutely airtight because you don’t want any evaporation.

FAQ

Q: Can I use ground coffee instead of whole beans?

A: It’s strongly advised against. Ground coffee will over-extract very quickly, leading to excessive bitterness and a muddy texture that’s difficult to strain out. Stick to whole beans for the best results.

Q: What kind of bourbon should I use?

A: Use a bourbon you enjoy drinking on its own. A mid-shelf bourbon is usually perfect. Avoid anything too harsh or overly flavored, as those notes will be amplified.

Q: How long should I infuse the bourbon?

A: Anywhere from 24 to 48 hours is typical, but it depends on your taste. Start tasting after 24 hours and continue every 8-12 hours until you reach your desired flavor.

Q: My infused bourbon tastes bitter. What went wrong?

A: Most likely, you infused it for too long, or you used too many beans. Strain it immediately and consider diluting it with some un-infused bourbon to balance the flavor.

Q: Can I add other flavors besides coffee?

A: Absolutely! Once you’ve mastered the basic coffee infusion, you can experiment with adding things like vanilla beans, cinnamon sticks, or even a dried chili pepper during the last few hours of infusion.

Q: How should I store the coffee-infused bourbon?

A: Store it in a clean, airtight bottle in a cool, dark place, just like any other spirit. It should last for several months, though the flavor might evolve slightly over time.

Q: Will this make my bourbon taste like coffee liqueur?

A: Not exactly. This method infuses the flavor of coffee into the bourbon. It won’t be as sweet or syrupy as a commercial coffee liqueur unless you add sugar separately.
