Nutritional Profile: Vodka (40% ABV)
This analysis pertains to unflavored, unadulterated vodka with a typical alcohol by volume (ABV) of 40% (80 proof).
Caloric and Macronutrient Breakdown
| Metric | Per 100g | Per Standard Serving (1.5 fl oz / 44.36 mL) |
|---|---|---|
| Energy (Calories) | ~233 kcal | ~98 kcal |
| Protein | 0.0 g | 0.0 g |
| Total Carbohydrates | 0.0 g | 0.0 g |
| Sugars | 0.0 g | 0.0 g |
| Total Fat | 0.0 g | 0.0 g |
| Saturated Fat | 0.0 g | 0.0 g |
| Alcohol (Ethanol) | ~33.2 g | ~14.0 g |
Note: Caloric content primarily derived from ethanol (7 kcal/g). Calculations assume a density of 0.95 g/mL for 40% ABV vodka at 20°C and a pure ethanol density of 0.789 g/mL.
Key Micronutrients
Vodka, being a distilled spirit, is largely devoid of micronutrients.
- Vitamins: Negligible amounts or entirely absent.
- Minerals: Negligible amounts or entirely absent.
- Antioxidants: Absent.
Functional Impact
- Glycemic Index (GI): Not applicable (Vodka contains no carbohydrates; does not directly raise blood glucose).
- Glycemic Load (GL): Not applicable.
- Satiety Score: Low. Alcohol can suppress appetite in some contexts but is also associated with increased food intake. Direct satiety from vodka alone is minimal.
- Metabolic Impact: Primarily metabolized by the liver via alcohol dehydrogenase and aldehyde dehydrogenase pathways. Can impair gluconeogenesis and fat oxidation.
Physical Properties
- Density: Approximately 0.95 g/cm³ (or g/mL) for 40% ABV at 20°C.
- Volumetric Contraction: When ethanol and water are mixed, the resulting volume is slightly less than the sum of the individual volumes (e.g., 40 mL ethanol + 60 mL water yields <100 mL mixture). This phenomenon is inherent to its production and not typically a post-cooking effect, as vodka is rarely cooked in a manner that would induce further significant volumetric changes.
- Boiling Point: ~80-85°C (lower than water due to ethanol content).
- Freezing Point: Dependent on ABV, significantly lower than water (e.g., -26°C for 40% ABV).

The Nutritional Enigma of the Clear Spirit
Dr. Aria Vance, Lead Nutrition Data Scientist, NutriSnap
Another Tuesday, another dive into the liquid ghost that haunts so many diet logs: Vodka. It’s a metabolic landmine, deceptively simple. My God, where do you even begin with this stuff? From its frosty birth in the frigid plains of Eastern Europe centuries ago, originally a fiery medicine, later refined into the crystal-clear spirit we know today, vodka's journey is one of cultural ubiquity. It’s been a staple, a celebratory pour, a social lubricant. A truly fascinating history, really, stretching back to 14th-century Poland or Russia, depending on who you ask and what historical document you trust. "Little water," they called it. Not so little when it comes to the impact on one's daily intake.
Tracking vodka manually? A fool's errand. Seriously, it's a nightmare. People pour freely, often. A "shot" at home can be wildly different from a precisely measured jigger at a bar. Is it 1.5 ounces? Two? More? Who carries a kitchen scale to a party? No one. The sheer variability! Then there's the dilution. Ice melts, adding water, changing the effective concentration over time, if you're sipping. And mixers! Ah, the insidious mixers. Tonic water, cranberry juice, sodas—each a sugary vortex, adding hundreds of 'hidden' calories that most people simply don't account for. They log "vodka," thinking it's zero-carb, zero-fat, ignoring the accompanying caloric tsunami. It's a nutritional chameleon, blending into whatever cocktail it inhabits, making precise estimation incredibly tedious, frustrating even. Most just guess, throw a number down, and hope for the best. This isn't science; it's wishful thinking.
That's why NutriSnap is, frankly, revolutionary. We're cutting through this fog of uncertainty. Imagine: you snap a photo of your drink. Our forensic visual AI kicks in, instantly. It doesn't just recognize the glass, it estimates the liquid volume, even accounting for ice dilution. It can identify the probable mixer based on color and turbidity, cross-referencing against our vast database. No more guessing. No more underreporting. Precision. Finally. For every 'little water' out there, we're bringing clarity.
