What is healthier, cold brew or iced coffee?

•
6 min read

According to a 2022 study, cold brew coffee is found to contain fewer acidic compounds than traditionally hot-brewed coffee. As a result, the question of "what is healthier, cold brew or iced coffee?" isn't as simple as it seems, as the health benefits largely depend on personal preference, digestive sensitivities, and the amount of sugar and milk added.

Quick Summary

This article explores the nutritional differences between cold brew and iced coffee, examining factors like acidity, caffeine, and antioxidants to determine which beverage is the healthier option for different individuals. It also covers the impact of additives and brewing methods.

Key Points

  • Less Acidic: Cold brew is significantly less acidic than iced coffee, making it a better option for those with sensitive stomachs or acid reflux.

  • Higher Caffeine: Cold brew typically has a higher caffeine concentration per serving due to its longer steeping process.

  • More Antioxidants in Iced: While both contain antioxidants, hot-brewed iced coffee may have higher levels compared to cold brew.

  • Additives Control Calories: The number of calories in either drink depends almost entirely on the amount of milk, sugar, and syrups added.

  • Flavor Profile: Cold brew is known for its smoother, sweeter, and less bitter taste, while iced coffee has a brighter, more acidic flavor profile.

  • Personal Preference is Key: The healthier choice depends on individual factors like caffeine tolerance, taste, and digestive sensitivity.

Cold Brew vs. Iced Coffee: The Health-Conscious Comparison

When the temperatures rise, many turn to chilled coffee beverages for a refreshing caffeine fix. While iced coffee and cold brew may appear similar, their distinct brewing methods create notable nutritional differences that can influence your health. Understanding these distinctions is key to choosing the beverage that best suits your dietary needs and sensitivities.

The Brewing Method Matters

The fundamental difference between cold brew and iced coffee lies in how they are brewed. This process is the primary driver of their nutritional profiles.

Cold Brew

  • Method: Coarsely ground coffee beans are steeped in cold or room-temperature water for 12 to 24 hours.
  • Effect: The slow, low-temperature extraction results in a less acidic, smoother, and naturally sweeter coffee concentrate.

Iced Coffee

  • Method: Standard hot-brewed coffee that is cooled and then poured over ice.
  • Effect: This method retains the flavor and acidity of hot coffee, which can sometimes taste more bitter or diluted as the ice melts.

Acidity and Digestive Comfort

For many, the most significant health-related factor is acidity. The heat in traditional brewing methods extracts more acidic compounds and oils from the coffee beans.

  • Cold Brew: Studies suggest cold brew can be up to 70% less acidic than hot-brewed coffee, making it gentler on the stomach and teeth. This can be particularly beneficial for those with sensitive stomachs, acid reflux, or GERD.
  • Iced Coffee: Because it is brewed hot, iced coffee retains a higher acidity level, which can cause digestive issues for some individuals.

Caffeine Content and Your Jolt of Energy

The caffeine kick you get from your coffee can vary significantly depending on the brewing method. Cold brew's extended steeping time and higher coffee-to-water ratio often result in a more caffeinated beverage.

  • Cold Brew: Typically contains a higher caffeine concentration per serving, especially when consumed as a concentrate. This provides a potent and sustained energy boost for those who need a stronger jolt.
  • Iced Coffee: Generally has a comparable caffeine level to hot coffee, though it can be diluted by melting ice. It is a more moderate option for those with caffeine sensitivity.

Antioxidants: Hot vs. Cold Brewing

Coffee is a source of antioxidants, which help protect the body from oxidative stress. However, the brewing temperature affects how these compounds are released.

  • Hot Coffee: Research suggests that hot brewing extracts more antioxidants than cold brewing. One study even indicated that hot coffee could have 50% more antioxidants.
  • Cold Brew: While it may contain fewer total antioxidants than hot coffee, cold brew is still a good source of these beneficial compounds.
  • Iced Coffee: Since it's brewed hot, iced coffee will have a similar antioxidant profile to hot coffee.

The Real Deal-Breaker: Additives

Ultimately, the healthfulness of your coffee depends less on the brewing method and more on what you add to it.

  • Plain and Black: When consumed black, both cold brew and iced coffee are virtually calorie-free.
  • Sweeteners and Creamers: The addition of sugar, flavored syrups, milk, or cream can drastically increase the calorie count, sugar content, and fat, turning a healthy beverage into a calorie-laden treat. Cold brew's natural sweetness often requires fewer additives to taste good, potentially making it the healthier choice by default.

Comparison Table

Feature Cold Brew Iced Coffee
Brewing Method Steeps grounds in cold water for 12-24 hours Brews hot coffee, then chills it over ice
Acidity Level Significantly lower, making it gentler on the stomach Higher, similar to hot-brewed coffee
Caffeine Content Generally higher and more concentrated Comparable to hot coffee, but can be diluted
Antioxidants Contains antioxidants, though potentially fewer than hot coffee Contains more antioxidants due to hot brewing
Flavor Profile Smoother, sweeter, and less bitter Brighter, more acidic, with a sharper taste
Calorie Count (Black) Virtually calorie-free Virtually calorie-free
Primary Health Benefit Easier on the digestive system and less likely to cause acid reflux More antioxidants, but depends on tolerance for acidity

Conclusion

Determining what is healthier, cold brew or iced coffee ultimately depends on your individual health concerns and taste preferences. For those with a sensitive stomach or acid reflux, the lower acidity of cold brew is a clear winner. Its naturally smoother flavor may also reduce the need for high-calorie additives. Conversely, if your primary concern is maximizing antioxidant intake, and you can tolerate the acidity, iced coffee brewed hot may provide a slight edge. Regardless of your choice, the healthiest option for both beverages is to enjoy them black or with minimal, healthy additions to avoid excess sugar and calories.

Frequently Asked Questions

Is cold brew bad for acid reflux? No, cold brew is typically better for acid reflux than regular iced coffee because its low-temperature brewing process extracts fewer acidic compounds, making it much gentler on the stomach.

Does cold brew coffee have more caffeine? Yes, in most cases, cold brew has a higher caffeine concentration than iced coffee due to its higher coffee-to-water ratio and longer steeping time.

What is the difference between cold brew and iced coffee taste? Cold brew has a smoother, sweeter, and less bitter flavor profile, while iced coffee often tastes brighter, more acidic, and can be more bitter, similar to hot coffee.

Which is better for weight loss, cold brew or iced coffee? Neither is inherently better for weight loss when consumed black, as they are both very low in calories. However, cold brew's natural sweetness may help you avoid sugary additives, which is often better for weight management.

Do both cold brew and iced coffee have antioxidants? Yes, both beverages contain antioxidants, but studies suggest that hot brewing extracts more, so iced coffee may have a slightly higher content. Both are still beneficial.

Is it better to drink cold brew black? Drinking cold brew black is the healthiest option, as it avoids the added sugar and calories from milk, syrups, and creamers.

Why does cold brew take so long to make? Cold brew requires a long steeping time (12-24 hours) because it relies on time rather than heat to extract flavor and caffeine from the coffee grounds.
