Karsk Recipe
Measured Home Karsk
One serving: 200 ml (6.8 US fl oz) black coffee and 20 ml (4 US tsp) unflavored vodka at 40% ABV. Sugar is optional. These are this guide's home quantities; Norwegian descriptions of karsk do not establish one fixed national ratio.
Use a 250–300 ml (8.5–10.1 US fl oz) heatproof mug, a teaspoon and a milliliter measure. Start with freshly brewed coffee you enjoy black; the drip-coffee guide covers the base preparation. The 220 ml (7.4 US fl oz) ingredient total leaves headroom.

Adding the optional sugar brings the estimate to 60 kcal and 4 g total sugar.
Karsk Ratio and Spirit Strength
How Strong Is This Karsk?
The recipe uses ten parts coffee to one part spirit by volume. That describes the poured ingredients, not the finished drink's alcohol percentage. The vodka portion contributes 20 ml (4 US tsp) × 40% = 8 ml pure alcohol.
Dividing that by the 220 ml (7.4 US fl oz) ingredient total gives about 3.6% nominal ABV. This is an input calculation, not a measurement of the served drink: it assumes additive volumes and makes no allowance for evaporation, temperature or the optional dissolved sugar. Different pours or bottle strengths change it.

| Same 20 ml (4 US tsp) spirit pour | Pure alcohol supplied | With 200 ml (6.8 US fl oz) coffee: nominal ABV |
|---|---|---|
| 40% ABV, this recipe | 8 ml | 3.6% |
| 60% ABV, comparison only | 12 ml | 5.5% |
The second row shows why the bottle’s ABV matters. Extra coffee dilutes the alcohol concentration but does not remove alcohol from the portion already poured. Likewise, replacing sugar with no sugar does not remove the alcohol's calories.
Why Not Measure with a Coin?
Norsk Kaffeinformasjon records the traditional story of hiding a coin beneath coffee and adding clear spirit until it reappears. It also describes how this could produce an unexpectedly strong drink. Visibility is not a calibrated alcohol measure: coffee opacity, cup depth and lighting all affect what you see. Use a milliliter measure and leave the coin out of the drink.
What Does Karsk Taste Like?
This measured Karsk drinks much like hot black coffee with an added warming finish. Unflavored vodka brings less of its own aroma than rum, brandy or a sweet liqueur, leaving the coffee’s bitterness, acidity and body easy to recognize. The unsweetened version has a comparatively dry finish and no dairy richness.
I prefer a rounded coffee with toasted-nut notes here because its familiar sweetness makes a comfortable counterpoint to the spirit’s warmth. The optional sugar gives a softer, sweeter finish if that is what you enjoy. With so few ingredients, choosing the coffee makes a noticeable difference to the whole mug.
I taste the measured coffee-and-spirit mixture before adding sugar.
Karsk Caffeine, Alcohol and Sugar
Calories and Sugar Per Serving
The snapshot and recipe nutrition describe the unsweetened base. The optional sugar is shown separately:

| Defined serving | Estimated calories | Total sugar | Added sugar |
|---|---|---|---|
| 200 ml (6.8 US fl oz) coffee + 20 ml (4 US tsp) 40% vodka | 45 kcal | 0 g | 0 g |
| Same drink + 4 g (1 US tsp) granulated sugar | 60 kcal | 4 g | 4 g |
Ingredient and alcohol calculation
For the spirit reference, Pernod Ricard lists Absolut Vodka at 40% ABV with 221 kcal and 0 g sugar per 100 ml. Its 20 ml portion therefore adds 44.2 kcal. Using USDA generic ingredient estimates, the 200 ml coffee portion supplies 2 kcal, giving 46 kcal before rounding. The optional sugar adds 15.5 kcal, making 62 kcal before rounding. Displayed estimates are rounded to the nearest 5 kcal.
These calculations use the named vodka label and generic USDA coffee/sugar records, not laboratory nutrition measurements. Other spirits, flavored vodkas or sweeteners need their own labels. The vodka producer also declares 31.6 g alcohol per 100 ml: this 20 ml pour supplies approximately 6.3 g alcohol. Its calories are included even when sugar is zero.
How Much Caffeine Is in Karsk?
The 200 ml (6.8 US fl oz) coffee portion has an 80 mg caffeine reference, scaled from Mayo Clinic’s 96 mg per 237 ml brewed coffee. Actual caffeine depends on the coffee and extraction.
Decaf is an option if you want less caffeine, but use the coffee's own information rather than assuming zero. Changing to decaf does not change the alcohol contribution.
Karsk vs. Other Coffee-and-Spirit Drinks
| Drink | Useful distinction |
|---|---|
| Karsk | Coffee and spirit, sometimes sugar; cream is not required |
| Caffè corretto | A small espresso with an alcoholic addition |
| Irish coffee | Whiskey coffee with sugar and a cream float |
| Pharisäer | Rum coffee beneath whipped cream |
| Carajillo | Coffee with spirit or liqueur; the local style affects ingredients and service |
Replacing vodka with rum or brandy changes the spirit character. Adding cream creates another variation. Name those additions when serving instead of assuming every coffee-and-spirit drink tastes or pours the same.
Adjusting Your Karsk
| Problem | Useful adjustment |
|---|---|
| Alcohol dominates | Use less measured vodka in the next serving; check its ABV before substituting bottles |
| Coffee is bitter | Adjust the brewed coffee first; sugar can change balance but will not correct every brewing fault |
| Weak or watery | Use normally brewed coffee rather than pre-diluting it |
| Sugar remains | Stir the optional measured sugar thoroughly while the coffee is hot |
| Mug overflows | Leave room for the spirit; 200 ml (6.8 US fl oz) is coffee input, not final volume |
Karsk and Regional Identity
Karsk is closely associated with Trøndelag, though Norsk Kaffeinformasjon also records it around Mjøsa, where the name kniks appears, and elsewhere as kaffedoktor. Its short ingredient list leaves room for strong local opinions about the coffee, spirit and even the cup.
Those opinions surfaced at a karsk competition during Trøndelag’s 2018 coffee festival. Idar André Ellingsen won with Colombian rum, French curaçao and naturally processed Ethiopian coffee. The festival magazine records good-humored objections from drinkers who felt the result had wandered too far from karsk. The story captures the pull between a familiar regional drink and the urge to experiment.
Practical Detail
What to Measure Before Serving
Measure the finished black coffee, then the spirit volume, and read the bottle ABV. Keep optional sugar separate. Those three checks tell you more than the color of the cup, the size of a casual splash or the coin story.
Serve promptly in a heatproof vessel, allowing the drink to cool to a comfortable sipping temperature. The calculations count the alcohol poured in; they do not claim that a hot cup has evaporated it away.
