Pisco (Grape Brandy) - Nutritional Profile
This nutritional analysis focuses on Pisco as a distilled alcoholic beverage, typically 38-48% Alcohol by Volume (ABV). Calculations are based on an average 40% ABV (80 proof) Pisco.
A. Caloric and Macronutrient Breakdown
| Component | Per 100g | Per Standard Serving (44 mL / 1.5 fl oz) |
|---|---|---|
| Energy | 221 kcal (925 kJ) | 90 kcal (377 kJ) |
| Protein | 0 g | 0 g |
| Carbohydrates | 0 g (of which Sugars: 0 g) | 0 g |
| Fat | 0 g (of which Saturated Fat: 0 g) | 0 g |
| Alcohol | ~34.5 g | ~14.0 g |
Note: The primary caloric contribution in Pisco is from alcohol (ethanol), which provides approximately 7 kcal/g.
B. Key Micronutrients (Vitamins, Minerals, Antioxidants)
Pisco, as a highly distilled spirit, contains negligible amounts of vitamins, minerals, or significant antioxidants. The distillation process effectively removes most micronutrients present in the original grape must.
- Vitamins: Trace amounts, generally considered 0% Daily Value (DV).
- Minerals: Trace amounts, generally considered 0% DV.
- Antioxidants: Negligible; the processing largely eliminates the polyphenols found in grapes.
C. Functional Impact
- Glycemic Index (GI): Not directly applicable as Pisco contains no carbohydrates. However, alcohol metabolism can impact blood glucose levels.
- Glycemic Load (GL): 0 (per 100g or serving) due to absence of carbohydrates. Nevertheless, alcohol consumption, particularly without food, can lead to transient hypoglycemia or affect insulin sensitivity.
- Satiety Score: Low. While calorically dense, alcohol tends to reduce satiety signals and can stimulate appetite, potentially leading to increased food intake.
D. Physical Properties
- Density: Approximately 0.916 g/cm³ (at 20°C for 40% ABV Pisco). This density is lower than water due to the presence of ethanol.
- Volumetric Contraction after Cooking: Not applicable. Pisco is consumed as a beverage, not typically cooked in a way that would induce significant volumetric contraction. Any reduction in volume during cocktail preparation is due to evaporation or dilution.

Why Pisco Is Difficult to Track
Dr. Aria Vance, Lead Nutrition Data Scientist at NutriSnap
Bloody Pisco. It's not just a spirit; it's a cultural cornerstone, a liquid whisper from the Andes that utterly baffles anyone trying to track their intake manually. We're talking ancient history here, pre-dating modern nation-states, back to colonial Peru and Chile, vying for dominion over this exquisite grape brandy. A vibrant, complex history, a spirit with DO – Denomination of Origin – protecting its very essence. So much more than just fermented grapes, right? A distillation of heritage.
But try telling that to someone meticulously logging calories with a kitchen scale. Forget it. The sheer variability is a nightmare. Pisco isn't just "Pisco." There's Puro from a single grape varietal, Aromática bursting with Muscat notes, and then Mosto Verde, distilled from partially fermented must, a richer, more viscous beast. Each with slightly different residual sugars, different densities, different ABVs. Some bottles hover around 38%; others punch hard at 48%. That's a huge caloric swing! You can't just slap a generic "brandy" entry into your food diary and call it a day. That's a gross oversimplification, a disservice to both the spirit and your health goals.
Then there's the serving. Oh, the serving! Who measures 44 milliliters for a Pisco Sour? Nobody. People free-pour. Bartenders, with their practiced flourish, eyeball it. At home, after a long day, a "splash" can easily become a double. And we haven't even touched on cocktails. A Pisco Sour isn't just Pisco; it's lime juice, egg white, simple syrup. Sugar, sugar, and more sugar, all adding hidden calories, fundamentally altering the nutritional profile. How do you accurately account for the density of that foamy head? The volumetric contraction of the ice melting slightly into your drink? It's a chaotic mess of estimation and guesswork. Utterly tedious. Incredibly error-prone.
The manual process—scanning a barcode (if it even has nutritional info, which most spirits don't beyond ABV), then attempting to estimate liquid volume, then factoring in all the mixers—it's not just time-consuming; it's demoralizing. It’s why people give up. They throw their hands up in exasperation, deciding tracking alcohol is simply too much trouble. And that, dear reader, is precisely why NutriSnap exists. This is where forensic visual analysis shines. Snap a photo of your Pisco Sour. Our AI, trained on thousands of images, doesn't just see a drink. It discerns the cocktail components, estimates the Pisco volume from the ice-liquid ratio, factors in the foam, and accounts for potential syrup additions. No scales. No guesswork. Just a picture. Finally, a solution for the discerning Pisco enthusiast who also cares about their macros. My sanity is saved.
