What to check first

Brewer type and filter type

For this process, you’re not really “brewing” in the traditional sense. The goal is to extract flavor from the coffee beans into the vodka. Think of it more like a cold soak. You won’t need a coffee maker. What you do need is a good way to strain out the coffee grounds later. A fine-mesh sieve, cheesecloth, or even a coffee filter (though that can be slow) will work.

Water quality and temperature

This applies more to drinking coffee, but it’s worth mentioning for the vodka. Start with a decent, neutral vodka. You don’t need top-shelf, but avoid the cheapest stuff. It should taste clean. For the coffee itself, if you were brewing it, water quality matters. For infusion, the vodka is your “water.”

Grind size and coffee freshness

This is where it gets important. You want a coarse grind. Think sea salt, not sand. Too fine a grind will make your vodka cloudy and might over-extract, leading to bitter flavors. Freshly roasted beans are key for the best flavor. Aim for beans roasted within the last few weeks.

Coffee-to-water ratio

This is your main variable. A good starting point is around 1/4 cup of whole beans per 750ml bottle of vodka. You can adjust this up or down based on how strong you want the coffee flavor. It’s better to start lower and add more coffee if needed.

Cleanliness/descale status

Sanitation is crucial. Make sure your jar or container is clean. You don’t want any weird bacteria interfering with your infusion. Also, ensure your straining tools are clean. We’re infusing, not fermenting.

Step-by-step (how to make coffee vodka)

1. Gather your supplies. You’ll need vodka, whole coffee beans, a clean jar with a lid, and straining tools.

• What “good” looks like: Everything is clean and ready to go. No dusty jars or questionable beans.
• Common mistake: Using pre-ground coffee. This makes straining a pain and can lead to a muddy infusion.
• Avoid it: Buy whole beans and grind them just before you start.

To start, you’ll need a clean infusion jar with a lid to hold your coffee and vodka. This is where the magic happens!

2. Grind your coffee beans. Aim for a coarse grind.

• What “good” looks like: Beans are broken up, but not powdery. Like coarse sand.
• Common mistake: Grinding too fine. This can result in a bitter, cloudy vodka.
• Avoid it: Use a burr grinder if you have one, and set it to the coarsest setting. If using a blade grinder, pulse it briefly.

3. Add coffee to your jar. Measure out your desired amount of coarsely ground coffee.

• What “good” looks like: The coffee is sitting at the bottom of the clean jar.
• Common mistake: Overfilling the jar with coffee. This can make it hard for the vodka to circulate and extract evenly.
• Avoid it: Stick to the recommended ratio or start with less. You can always add more later.

4. Pour in the vodka. Cover the coffee grounds completely with your chosen vodka.

• What “good” looks like: All the coffee grounds are submerged in vodka.
• Common mistake: Not using enough vodka to cover the grounds. This can lead to uneven infusion and potential mold growth.
• Avoid it: Make sure the liquid level is well above the coffee.

5. Seal the jar. Close the lid tightly.

• What “good” looks like: A secure seal. No leaks.
• Common mistake: A loose lid. This can lead to evaporation and potential contamination.
• Avoid it: Double-check the seal.

6. Infuse. Let the jar sit at room temperature, away from direct sunlight.

• What “good” looks like: The vodka will start to take on a brown hue. You might see some sediment settling.
• Common mistake: Forgetting about it or infusing for too long. Over-infusion leads to bitterness.
• Avoid it: Set a reminder to check it.

7. Taste test. After 12 hours, open the jar and carefully taste a small amount.

• What “good” looks like: You can taste the coffee flavor, but it’s not overpowering or bitter.
• Common mistake: Not tasting and assuming it’s done. This can lead to a weak or overly strong result.
• Avoid it: Taste it regularly, starting at the 12-hour mark.

8. Continue infusing (if needed). If the flavor isn’t strong enough, let it sit for another 12-24 hours, tasting every few hours.

• What “good” looks like: The coffee flavor is developing nicely to your preference.
• Common mistake: Infusing for days and days, making it bitter.
• Avoid it: Stop when the flavor hits your sweet spot. Generally, 24-48 hours is plenty.

9. Strain the vodka. Once you’re happy with the flavor, it’s time to separate the coffee.

• What “good” looks like: Clear-ish vodka, free of grounds.
• Common mistake: Rushing the straining process. This leaves sediment behind.
• Avoid it: Be patient. Let gravity do its work.

10. Double strain (recommended). For an extra-clear spirit, strain it again through a finer mesh or coffee filter.

• What “good” looks like: Very clear liquid.
• Common mistake: Skipping this step if you want a pristine spirit.
• Avoid it: If you’re particular about clarity, do it.

11. Bottle and store. Pour the finished coffee vodka into a clean bottle.

• What “good” looks like: Your finished product, ready for cocktails.
• Common mistake: Storing it improperly.
• Avoid it: Keep it in a cool, dark place. It doesn’t need refrigeration.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If the vodka tastes weak after 12 hours, then add more coffee grounds and infuse for another 12-24 hours because you need more coffee flavor extraction.
• If the vodka tastes bitter after 24 hours, then strain it immediately and store it because you’ve likely over-extracted.
• If you want a super-clear coffee vodka, then strain it a second time through a coffee filter because this will catch any remaining fine particles.
• If you’re using a dark roast coffee, then infuse for a shorter period because dark roasts can extract bitterness more quickly.
• If you prefer a subtle coffee note, then use less coffee or infuse for a shorter time because you want a lighter flavor profile.
• If you notice a lot of sediment after the first strain, then let it settle for a few hours before the second straining because this will help clarify the liquid.
• If the coffee grounds look like they’re expanding a lot, then you might have ground them a bit too fine, so be extra careful with straining.
• If you’re making this for a specific cocktail recipe, then taste it against the other ingredients before deciding the infusion time because balance is key.
• If you want to experiment, then try different types of coffee beans (e.g., single origin) because each will impart a unique flavor.
• If you are unsure about the infusion time, then err on the side of caution and infuse for less time because you can always add more coffee later, but you can’t take bitterness away.

FAQ

How much coffee should I use?

A good starting point is about 1/4 cup of whole beans per 750ml bottle of vodka. You can adjust this based on your taste preference, but it’s better to start with less and add more if needed.

How long should I infuse the vodka?

Typically, 12 to 48 hours is sufficient. Start tasting at 12 hours and continue every few hours until you reach your desired coffee flavor intensity. Over-infusing can lead to bitterness.

What kind of vodka is best?

A neutral, mid-range vodka works best. You don’t need anything fancy, but avoid the cheapest options as their off-flavors can interfere with the coffee infusion.

Can I use pre-ground coffee?

It’s strongly discouraged. Pre-ground coffee is too fine, making straining difficult and often resulting in a cloudy, gritty vodka. Always use whole beans and grind them yourself.

What if my coffee vodka is cloudy?

This usually means the coffee grounds were too fine, or you didn’t strain it thoroughly enough. Let it settle for a day or two, then carefully decant or re-strain it.

How should I store my coffee vodka?

Store it in a clean, airtight bottle in a cool, dark place, just like you would regular spirits. It doesn’t require refrigeration.

Can I use flavored coffee beans?

While you can, it might lead to overly complex or clashing flavors. It’s generally best to start with plain, high-quality coffee beans for a clean coffee infusion.

How long does coffee vodka last?

Properly stored, coffee vodka can last for a year or more. The alcohol acts as a preservative.
