What to check first
Brewer type and filter type
Your standard coffee maker, pour-over, or French press will work. Just know that garlic oils might linger. Consider using a dedicated brewer if you plan on doing this often. Paper filters can help catch some of the garlic solids, but they might also absorb some of the flavor. Metal filters will let more through.
Your standard coffee maker, pour-over, or French press will work. If you’re opting for a French press, consider investing in a quality one to ensure a good brew.
- Wash in warm, soapy water before first use and dry thoroughly
- Not for stovetop use
- Turn lid to close spout
- Easy-to-clean glass carafe
Water quality and temperature
Use good-tasting filtered water. The same rule applies here as with regular coffee – if your water tastes bad, your coffee will too. Aim for water temps around 195-205°F for most brewing methods. Too hot can scorch things, too cool and you won’t extract much.
Grind size and coffee freshness
Freshly roasted and ground beans are always best. For garlic coffee, a medium grind usually works well for drip or pour-over. If you’re using a French press, go a bit coarser. Stale coffee won’t do you any favors here; it’ll just taste flat and weird.
Coffee-to-water ratio
A good starting point is about 1:15 or 1:16 coffee to water. So, for every 1 gram of coffee, use 15-16 grams of water. This is a baseline. You might need to adjust this depending on how much garlic you use and how strong you want the overall brew.
Cleanliness/descale status
Make sure your brewer is clean. Seriously. Old coffee oils and residue will clash hard with garlic. If you haven’t descaled in a while, do it now. You want a clean slate for this experiment.
Step-by-step (brew workflow)
1. Prepare the garlic: Peel and thinly slice 1-3 cloves of fresh garlic. For a milder flavor, you can lightly roast the garlic slices in a dry pan over low heat until fragrant but not browned.
- What “good” looks like: The garlic is pliable and has a mellowed, slightly sweet aroma.
- Common mistake: Burning the garlic. This makes it bitter and acrid, ruining both the garlic and the coffee. Avoid high heat.
2. Add garlic to brewer: Place the prepared garlic slices at the bottom of your brewer (e.g., in the filter basket or French press carafe).
- What “good” looks like: The garlic is evenly distributed.
- Common mistake: Clumping the garlic. This can lead to uneven extraction. Spread it out.
3. Add coffee grounds: Add your freshly ground coffee on top of the garlic.
- What “good” looks like: The coffee grounds cover the garlic layer.
- Common mistake: Not ensuring the coffee is on top. If garlic is on top, it might float and not infuse properly.
4. Bloom the coffee: Pour just enough hot water (about twice the weight of the coffee) over the grounds and garlic to saturate them. Wait 30-45 seconds.
- What “good” looks like: The coffee grounds expand and release gas (a “bloom”).
- Common mistake: Pouring too much water too fast. This can wash grounds into the garlic or cause uneven saturation.
5. Continue brewing: Slowly pour the remaining hot water over the coffee and garlic in a circular motion.
- What “good” looks like: The water flows through evenly, extracting the flavors.
- Common mistake: Pouring too aggressively or all at once. This can lead to channeling and weak extraction.
6. Allow to steep (French Press): If using a French press, let it steep for about 4 minutes after the initial pour.
- What “good” looks like: The coffee and garlic have had adequate time to infuse.
- Common mistake: Steeping too long. This can over-extract the coffee and make the garlic flavor too dominant or bitter.
7. Press the plunger (French Press): Slowly and steadily press the plunger down.
- What “good” looks like: The plunger moves smoothly without excessive resistance.
- Common mistake: Forcing the plunger. This can create a mess and allow grounds to bypass the filter.
8. Serve immediately: Pour the garlic coffee into your mug right away.
- What “good” looks like: A fragrant, unique-looking brew.
- Common mistake: Letting it sit on the grounds. This will continue extraction and can lead to bitterness.
Common mistakes (and what happens if you ignore them)
| Mistake | What it causes | Fix |
|---|---|---|
| Using raw, un-roasted garlic | Harsh, pungent, and potentially unpleasant flavor | Lightly roast or infuse garlic slices before brewing. |
| Too much garlic | Overpowering, medicinal, or savory taste | Start with 1-2 cloves and adjust up or down in future brews. |
| Stale coffee beans | Flat, dull, and uninspired flavor | Use freshly roasted and ground coffee beans. |
| Incorrect grind size | Under-extraction (weak, sour) or over-extraction (bitter) | Match grind size to your brewing method (coarser for French press). |
| Water too hot or too cold | Scorched taste or weak extraction | Aim for 195-205°F. Check your kettle or thermometer. |
| Dirty brewing equipment | Off-flavors, rancid notes, and poor extraction | Clean and descale your brewer regularly. |
| Not blooming the coffee | Uneven extraction, sourness | Allow 30-45 seconds for the bloom before the main pour. |
| Pouring water too fast/aggressively | Channeling, weak spots, bitter spots | Pour slowly and steadily in a circular motion. |
| Not filtering enough garlic solids | Gritty texture, strong garlic sediment | Use a paper filter or a fine mesh sieve if needed. |
| Letting coffee sit on grounds too long | Over-extraction, bitterness | Serve immediately after brewing is complete. |
Decision rules (simple if/then)
- If the garlic flavor is too strong, then use less garlic next time because you can always add more.
- If the coffee tastes weak and sour, then try a finer grind or more coffee because you might be under-extracting.
- If the coffee tastes bitter and burnt, then try a coarser grind or less garlic because you might be over-extracting or the garlic is too roasted.
- If your French press has sediment, then ensure your grind is coarse enough and press the plunger slowly because this prevents grounds from escaping the filter.
- If you’re using a paper filter and the flavor seems muted, then consider using a metal filter or less garlic because paper filters can absorb oils.
- If the aroma is unpleasant, then check your garlic freshness and roasting level because old or burned garlic is the usual culprit.
- If the brew is too savory and not coffee-like, then reduce the garlic amount because the goal is a subtle infusion, not a garlic soup.
- If you notice an oily sheen on the surface, then it’s likely from the garlic; this is normal for this brew, but too much can indicate too much garlic.
- If the coffee tastes bland, then check your coffee-to-water ratio and freshness because blandness usually means something is off with the coffee itself.
- If you want a more intense garlic note without extra bitterness, then try infusing whole garlic cloves in hot water separately, then use that infused water to brew your coffee.
FAQ
Is garlic coffee a real thing?
Yes, it’s an unconventional beverage that some people enjoy for its unique savory profile. It’s not mainstream, but it exists.
How much garlic should I use?
Start with just one or two thin slices of garlic per cup. You can always add more in subsequent brews once you know how you like it.
Will my coffee taste like raw garlic?
Ideally, no. Lightly roasting or infusing the garlic mellows its raw bite, bringing out a more nuanced, slightly sweet flavor that complements the coffee.
Can I use any type of coffee bean?
You can use any beans you like, but a medium-roast coffee often balances well with the savory notes of garlic. Avoid very light or very dark roasts until you get a feel for the flavor.
What if my coffee has garlic sediment?
This can happen, especially with French presses or if the garlic pieces are very small. Using a paper filter can help, or you can strain the coffee through a fine-mesh sieve.
Does garlic coffee have health benefits?
While garlic has known health benefits, brewing it with coffee doesn’t automatically transfer or enhance these effects in a scientifically proven way. It’s primarily for flavor experimentation.
How do I clean my coffee maker after making garlic coffee?
Clean it thoroughly with soap and water, and run a descaling cycle if possible. Garlic oils can linger, so a good scrub is important to prevent flavor transfer to your next regular brew.
Is there a specific brewing method that works best?
Many methods can work, but pour-over or French press allows for more control over the infusion process. Experiment to see what you prefer.
