Quick answer: A 16oz black cold brew has 5-10 calories, 0g sugar, and 200-280mg of caffeine—significantly more than drip coffee. Its lower acidity makes it gentler on the stomach, but adding milk and sugar can increase calories to over 250.
Black Cold Brew: The Nutrition Facts
A typical 16oz / 473ml serving of black cold brew contains:
- Calories: 5-10 kcal
- Caffeine: 200-280mg (varies with bean and brew strength)
- Total fat: 0g
- Carbohydrates: 0-2g
- Protein: 0-1g
- Sodium: 5-10mg
- Antioxidants: ~200mg of polyphenols (mainly chlorogenic acid)
So when you see "cold brew has 0 calories" claims, they're approximately true for a black, unsweetened cup (all drinkware), the trace calories come from natural compounds extracted from the coffee bean itself.
Caffeine: Why Cold Brew Hits Harder
Cold brew typically has more caffeine per ounce than hot drip coffee, despite being brewed at room temperature. The reason: cold brew uses a higher coffee-to-water ratio (often 1:5 to 1:8) and a much longer steep time (12-24 hours) than hot brewing (1:15-1:17, 4-6 minutes).
Per 8oz / 240ml serving, the rough comparison:
- Cold brew (concentrate, undiluted): 200-300mg caffeine
- Cold brew (ready-to-drink, diluted): 100-150mg
- Drip coffee: 95-165mg
- Espresso shot (1oz): 60-75mg
- Iced coffee (hot-brewed, then chilled): 95-165mg (same as drip)
PRO TIPPro-tip: If you find cold brew concentrate too intense, try a 1:10 ratio steeped for just 12 hours. You'll get a smoother, ready-to-drink brew with caffeine levels closer to standard drip coffee.
If you're sensitive to caffeine, treat undiluted cold brew with respect, a single 16oz serving can contain more caffeine than two espresso doubles. Most coffee shops dilute their cold brew with water or milk before serving, but bottled concentrates are designed to be cut down.
When You Add Milk and Sugar
This is where cold brew nutrition explodes. A typical sweet-cream cold brew at a national chain, say a Starbucks Vanilla Sweet Cream Cold Brew, 16oz, contains:
- Calories: 250 kcal
- Sugar: 27-30g (about 7 teaspoons)
- Total fat: 14g
- Caffeine: 185mg
That's calorie-equivalent to a slice of pizza, mostly from sweetened cream and added flavor syrups. The same drink ordered black would be ~10 calories.
Cold Brew vs. Iced Coffee, Are They Different?
Yes, nutritionally they are slightly different. Iced coffee is hot-brewed then chilled; cold brew is steeped in cold water for 12-24 hours.
- Acidity: Cold brew is 67% less acidic than iced coffee (per UC Davis study). This makes it gentler on stomachs and teeth.
- Caffeine: Cold brew typically has 1.5-2x the caffeine of iced coffee at the same volume.
- Calories: Both are essentially calorie-free black, identical when sweetened.
- Antioxidants: Hot brewing actually extracts more antioxidants than cold brewing, iced coffee is slightly richer in polyphenols.
Health Benefits and Concerns
What are the benefits of low acidity?
Black cold brew offers the same proven coffee benefits in a low-acid form: antioxidants linked to reduced inflammation, modest cardiovascular protection (1-3 cups/day), and improved cognitive performance from caffeine. The lower acidity is genuinely beneficial for people with acid reflux or sensitive stomachs.
Are there any downsides to cold brew?
The same low-acid profile that's gentle on stomachs can make cold brew taste subtly less complex than hot coffee. Some of the bright, fruity notes that come from acid extraction in hot brewing are simply not present in cold brew. This is taste preference, not health.
PRO TIPPro-tip: To maximize antioxidants, try 'flash chilling' your coffee. Brew it hot with half the water, then pour it immediately over the other half as ice. This preserves more polyphenols than slow cold steeping.
The bigger health concern with cold brew is dose: high caffeine content combined with smooth taste makes it easy to drink fast. A 16oz cold brew chugged in 10 minutes hits very differently than the same caffeine spread over a slow morning coffee.
Homemade Cold Brew vs. Store-Bought
Homemade cold brew is dramatically cheaper and more controllable. Cost per liter, comparing typical figures:
- Homemade (100g coffee, $20/lb beans): ~$4 per liter
- Bottled cold brew (Stumptown, Chameleon, etc.): $12-18 per liter
- Coffee shop: $20-30 per liter equivalent
PRO TIPPro-tip: For the cleanest homemade cold brew, filter it twice. Once through a metal mesh to remove coarse grounds, then a second time through a paper filter to catch the fine sediment.
Homemade also lets you control the bean (look for low-acid roasts like our Stumptown picks), the strength, and any additives.
Bottom Line
If you drink it black: cold brew is one of the lowest-calorie, highest-caffeine coffee drinks available. ~10 calories, 200-300mg caffeine per 16oz. Perfectly fine for daily consumption.
If you order it sweetened with cream: you're drinking a 250-400 calorie dessert beverage. Treat it accordingly.
Frequently Asked Questions
How many calories does cold brew coffee have?
Black cold brew has 5-10 calories per 16oz serving, essentially zero. The calories come from trace compounds extracted from the coffee bean itself.
Once you add milk, cream, sugar, or syrup, calories increase dramatically: a sweetened cream cold brew at a national chain typically contains 200-300+ calories per 16oz.
How much caffeine is in cold brew?
A 16oz / 473ml serving of black cold brew contains 200-280mg of caffeine, depending on the bean and concentration. That is more than hot drip coffee at the same volume because cold brew uses a stronger ratio (1:5 to 1:8) and longer steep (12-24 hours).
Concentrated cold brew can contain up to 300mg per 16oz; diluted ready-to-drink versions sit closer to 100-150mg.
Does cold brew have sugar?
Black cold brew has 0g of sugar, coffee beans contain no natural sugar, and cold brewing adds none. If your cold brew has sugar, it was added: either by you, by a barista as syrup or sweetener, or by the bottler in flavored ready-to-drink products.
Always check the label on store-bought cold brew, since "cold brew" alone is not a guarantee of unsweetened.
Is cold brew healthier than regular coffee?
Cold brew is not inherently healthier in calories or antioxidants, it is actually slightly lower in antioxidants than hot-brewed coffee, since heat extracts polyphenols more efficiently.
Where cold brew wins is acidity: it is roughly 67% less acidic than hot coffee, which makes it gentler on the stomach and teeth. For people with acid reflux or sensitive teeth, cold brew is the better daily choice. For everyone else, both are healthful.
Does cold brew help with weight loss?
Black cold brew can support weight loss only because it is essentially calorie-free and the caffeine modestly raises metabolic rate. It is not a magic weight-loss drink.
Adding milk, cream, sugar, or syrup completely cancels this effect, a 250-calorie sweetened cold brew daily adds up to 25 pounds per year if not offset elsewhere. If weight is a goal, drink it black or with a splash of unsweetened milk.
