Does Kahlua Have Caffeine? How Much per Shot
Yes, Kahlua has caffeine. The brand states that Kahlua contains about 100 mg of caffeine per liter, which works out to roughly 5 mg per standard 1.5 oz pour. That is about one-twentieth of the caffeine in an 8 oz cup of brewed coffee (about 95 mg per USDA). Figures verified September 2026.
| Pour size | Volume (mL) | Caffeine (mg) | mg per fl oz |
|---|---|---|---|
| 1 fl oz | 29.6 mL | ~3.0 mg | ~3.0 |
| 1.5 fl oz (standard shot) | 44.4 mL | ~4.4 mg | ~3.0 |
| 2 fl oz | 59.1 mL | ~5.9 mg | ~3.0 |
| 750 mL bottle | 750 mL | ~75 mg | ~3.0 |
| 1 L bottle | 1,000 mL | ~100 mg | ~3.0 |
All values computed from the brand's stated 100 mg per liter. The brand rounds a 1.5 oz pour to "about 5 mg."
How Much Caffeine Is in Kahlua?
Kahlua's FAQ puts it plainly: the liqueur contains about 100 ppm caffeine, equal to 100 mg per liter. The caffeine comes from the arabica coffee beans used in production. Kahlua itself is a blend of rum, sugar, vanilla and coffee, created in 1936 in Veracruz, Mexico and now owned by Pernod Ricard.
Why so little caffeine? A coffee liqueur is mostly sugar, water and spirit. A standard pour is 1.5 oz, not 8 oz. And the coffee undergoes processing that dilutes its caffeine far below what you get from a brewed cup.
One note on rounding: 100 mg/L across 1.5 fl oz (44.4 mL) is actually about 4.4 mg. The brand rounds up to "about 5 mg." Either number is trivial compared to a cup of drip coffee.
The USDA's generic entry for a 63-proof coffee liqueur lists 9 mg per fl oz, which is three times higher than Kahlua's brand figure. That USDA number is a category average across multiple products, not a Kahlua measurement. Use the brand's own 100 mg/L figure for Kahlua specifically.
Does Every Kahlua Flavor Have Caffeine?
All Kahlua variants are made with coffee, so all contain some caffeine. The brand publishes "about 100 mg/L" for the line but does not break out a separate caffeine figure for each flavor.
| Variant | ABV | Caffeine per liter | Status (US, Sep 2026) |
|---|---|---|---|
| Original | 20% | ~100 mg (brand) | Current |
| Vanilla | See label | Not separately published | Current |
| Salted Caramel | 20% | Not separately published | Current |
| Mint Mocha | See label | Not separately published | Current |
| Chili Chocolate | See label | Not separately published | Current |
| Especial | 36% | Not separately published | Current |
| Blonde Roast Style | N/A | N/A | Discontinued |
| Espresso Martini Can | N/A | N/A | Discontinued |
If a variant matters to you for health reasons, the safe assumption is that any Kahlua made with real coffee carries caffeine in the same range as the Original.
Kahlua Caffeine vs. Coffee, Espresso and Cola
A side-by-side comparison puts the numbers in context.
| Drink / Product | Serving | Caffeine (mg) | Source |
|---|---|---|---|
| Kahlua (1.5 oz pour) | 1.5 fl oz | ~5 | Kahlua FAQ |
| Brewed coffee | 8 fl oz | ~95 | USDA |
| Espresso (single shot) | 1 fl oz | ~63 | USDA |
| Coca-Cola | 12 fl oz | 34 | Coca-Cola |
| Decaf coffee | 8 fl oz | 2–15 | FDA |
| Roon (caffeine pouch, not a drink) | 1 pouch | 80 | Roon |
A shot of Kahlua sits closer to decaf coffee than to anything else on the list. You would need to drink roughly 19 shots of Kahlua to match one cup of brewed coffee, which is neither practical nor advisable given the alcohol.
How Much Caffeine Is in an Espresso Martini?
Almost all of the caffeine in an espresso martini comes from the espresso, not the Kahlua. Kahlua's own recipe calls for Kahlua, vodka and freshly pulled espresso, shaken with ice. Equal parts is the common build, though bars vary.
With a single 1 oz shot of espresso (~63 mg caffeine) and 1 oz of Kahlua (~3 mg), the drink totals about 66 mg of caffeine. Roughly 95% of that is the espresso. A double-shot build pushes the total to about 129 mg.
The takeaway: if you are avoiding caffeine late at night, the espresso is the ingredient to watch, not the Kahlua.
How Much Caffeine Is in a White Russian, Black Russian or Mudslide?
These cocktails use Kahlua but skip the espresso. That means the only caffeine source is the Kahlua itself: about 3 mg per fluid ounce of Kahlua in the glass.
Most White Russian and Black Russian recipes call for 1 to 2 oz of Kahlua, so you are looking at roughly 3 to 6 mg of caffeine per drink. A Mudslide follows the same math. These are trace amounts by any measure.
Does Other Coffee Liqueur Have Caffeine? (Mr Black, Tia Maria)
Yes, any liqueur made with real coffee will contain some caffeine. The question is how much, and most brands do not say.
Mr Black is a cold brew coffee liqueur made with 100% specialty-grade Arabica coffee and vodka. The brand's FAQ does not publish a caffeine figure. VinePair reports that each 1 oz pour contains "about 25 to 40 percent" of the caffeine in a shot of espresso, but that is a journalist's characterization, not a brand-confirmed milligram count. Third-party sites quote figures like 25 mg per ounce and 1,100 mg per liter, but none cite a brand source.
Tia Maria is even murkier. Third-party figures range from 0.5 mg to 105 mg per serving, and none trace back to the manufacturer. The brand does not publish caffeine data.
The USDA's generic entry for coffee liqueur (63 proof) is 9 mg per fl oz, which may serve as a rough category benchmark. But for a specific product, only a brand-confirmed figure is reliable, and most brands have not provided one.
Will Kahlua Keep You Awake?
At about 5 mg per standard pour, Kahlua's caffeine sits in the same range as a cup of decaf coffee (2 to 15 mg per 8 oz, per FDA). For most adults, that is not enough to interfere with sleep.
An espresso martini is a different story. At 63 to 130 mg depending on the build, the espresso component can absolutely affect sleep, especially if consumed in the evening. Caffeine's half-life is roughly 5 to 6 hours for most people, so a late-night espresso martini means caffeine is still circulating at bedtime. (More on timing: How long does caffeine stay in your system?)
Alcohol itself disrupts sleep quality regardless of caffeine content. That is worth remembering for any nightcap.
Caffeine Does Not Cancel Out Alcohol
The CDC states that caffeine mixed with alcohol does not reduce alcohol's effects on the body, does not lower breath or blood alcohol concentration, and can make people feel more alert than they actually are, leading to more drinking and greater risk.
In 2010, the FDA issued warning letters to four makers of caffeinated malt beverages (including Phusion Projects, maker of Four Loko), calling added caffeine an "unsafe food additive." That action targeted caffeine directly added to malt beverages, not coffee liqueurs, where caffeine is a natural component of the coffee ingredient.
The bottom line for adults 21 and over: a cocktail containing caffeine is not somehow safer or more functional than one without it. Caffeine does not sober you up. Never drive after drinking. If you are pregnant, breastfeeding, taking medications, or managing a health condition, talk to your clinician about both caffeine and alcohol.

The Numbers, Without the Nightcap
Kahlua contains about 5 mg of caffeine per 1.5 oz pour, roughly on par with decaf coffee. That trace amount comes from the arabica beans in the recipe, and it is unlikely to keep most people awake or push anyone past the FDA's 400 mg daily guideline. The espresso in an espresso martini is the real caffeine source. And no amount of caffeine changes what alcohol does to your body or your sleep.
Frequently Asked Questions
Does Kahlua have caffeine in it?
Yes. Kahlua contains about 100 mg of caffeine per liter, which comes from the arabica coffee beans used to make it. A standard 1.5 oz pour delivers roughly 5 mg of caffeine.
How much caffeine is in a shot of Kahlua?
About 4.4 mg in a 1.5 oz shot, computed from the brand's 100 mg/L figure. Kahlua rounds this to "about 5 mg." Either way, it is a fraction of the ~95 mg in an 8 oz cup of brewed coffee.
Is there caffeine in a White Russian?
Yes, but very little. The only caffeine source is the Kahlua, at roughly 3 mg per fluid ounce. A typical White Russian with 1.5 oz of Kahlua contains about 4 to 5 mg of caffeine.
Does an espresso martini have a lot of caffeine?
Relative to a standard cocktail, yes. A single-shot espresso martini contains about 66 mg of caffeine, and roughly 95% of that comes from the espresso, not the Kahlua. A double-shot build reaches about 129 mg.
Does Kahlua have more caffeine than coffee?
No. An 8 oz cup of brewed coffee contains about 95 mg of caffeine (USDA). A 1.5 oz shot of Kahlua has about 5 mg. You would need roughly 19 shots of Kahlua to match one cup of coffee.
Is there a caffeine-free coffee liqueur?
No verified caffeine-free coffee liqueur exists as of September 2026. Any liqueur made with real coffee beans will contain some caffeine. If you need to avoid caffeine entirely, check with the manufacturer or choose a non-coffee liqueur.
When You Want the Caffeine Without the Cocktail
Most people overestimate what Kahlua delivers, caffeine-wise. Five milligrams is barely a nudge. If you actually want sustained alertness, that is a daytime job, not something to outsource to a nightcap.
Roon is a zero-nicotine, zero-sugar oral pouch with a labeled dose: 80 mg caffeine, 60 mg L-theanine, 25 mg methylliberine (Dynamine) and 5 mg theacrine (TeaCrine). The methylliberine slows caffeine clearance. In a randomized, double-blind crossover PK study (n=12), co-administration of methylliberine with caffeine cut oral clearance from 41.9 to 17.1 L/hr and extended caffeine's half-life from 7.2 to 15 hours, with no increase in peak concentration. That study used 100 mg methylliberine and 150 mg caffeine, roughly 4x and 1.9x Roon's doses, so the magnitude of the effect at Roon's lower dose has not been separately measured. The mechanism is directionally the same, and Roon's felt window is 6 to 8 hours. That longer tail also means you should stop at least 8 hours before bed.
Onset is 5 to 10 minutes. Pricing starts at $9.16 per tin on a 12-tin subscription ($0.61 per pouch), or $15.00 per tin one-time (4 tins, $1.00 per pouch). There is a 30-day money-back guarantee on your first order only. Roon contains sucralose and is not a drink, not a cocktail ingredient, and not a substitute for medical advice. It is a known dose for a known duration, best used in the morning or early afternoon.
