So as you go up in size, the caffeine content increases.

    • Contains approximately 200 mg of caffeine
    • Highest caffeine content of the sizes
    • Provides a strong caffeine jolt
    • Similar to some Starbucks coffee sizes
    • Best for avid coffee drinkers

How McDonald’s Iced Coffee Compares

McDonald’s iced coffee tends to have less caffeine than the same size at Starbucks or Dunkin’ Donuts. Here’s a more detailed comparison:


  • Tall (12 oz): 120mg
  • Grande (16 oz): 165mg
  • Venti (24 oz): 235mg

Starbucks offers more customization options compared to McDonald’s. You can customize the milk, sweeteners, flavors, and toppings. The caffeine content is higher across the board.

Dunkin’ Donuts

  • Small (10 oz): 198mg
  • Medium (24 oz): 297mg
  • Large (32 oz): 396mg

Dunkin’ Donuts iced coffee has significantly higher caffeine content than McDonald’s. Even a small Dunkin’ Donuts has nearly double the caffeine of a McDonald’s small.

However, McDonald’s large iced coffee with 200mg caffeine comes closer to the 235mg in a Starbucks Venti.

Key Differences:

  • Starbucks and Dunkin’ offer more customization options for milk, flavors, sweeteners, and toppings
  • Caffeine content is higher at Starbucks and Dunkin’ across all sizes
  • McDonald’s has fewer flavor choices – mostly just different syrups
  • McDonald’s is more affordable and convenient as a fast food option

The Bottom Line

While not as customizable as Starbucks or Dunkin’, McDonald’s offers a more affordable, convenient iced coffee option. It has a bit less caffeine but can still give a caffeine boost in a pinch. For maximum caffeine, go with a large McDonald’s iced coffee.

McDonald’s Brewing Method

According to McDonald’s, they make their iced coffee with a double brew method. Here’s how it works:

  1. Hot coffee is brewed at double strength
  2. The hot concentrated coffee is then poured over ice to rapidly chill it
  3. The chilled coffee is diluted with additional water and ice

This method results in a stronger coffee flavor while still delivering a refreshing, cold drink. The double brew gives McDonald’s iced coffee more caffeine kick than typical iced coffee.

Additional Ingredients

In addition to brewed coffee, McDonald’s adds these ingredients to their iced coffee:

  • Sugar
  • Potassium sorbate (preservative)
  • Citric acid
  • Milk or cream
  • Flavorings (caramel, mocha, etc.)

The sugar and cream add a good amount of calories. A medium McDonald’s iced coffee has 180 calories, mainly from the 28 grams of added sugar.

Health Benefits and Risks

The caffeine in McDonald’s iced coffee provides some health benefits in moderation, such as:

  • Increased energy and alertness
  • Improved focus and concentration
  • Enhanced athletic performance

However, too much caffeine can cause negative effects like:

  • Jitters, anxiety, and restlessness
  • Sleep issues
  • Digestive problems
  • High blood pressure
  • Rapid heart rate

Experts recommend limiting caffeine intake to 400mg per day to avoid these issues. A McDonald’s large iced coffee contains 200mg caffeine, so it’s best to avoid going overboard with size and frequency.

Tips for Ordering

Here are some tips for ordering McDonald’s iced coffee to control caffeine and calorie intake:

  • Stick to small or medium sizes if you’re caffeine sensitive
  • Request less added sugar and cream or milk
  • Opt for skim or nonfat milk to reduce calories
  • Try flavored options like vanilla or mocha for variety
  • Substitute decaf if you want the taste but no caffeine
  • Avoid ordering late in the day if caffeine disrupts your sleep

The Bottom Line

McDonald’s iced coffee offers a tasty, affordable option for people who want to enjoy iced coffee on the go. While the caffeine content is less than Starbucks and Dunkin’ Donuts, it still provides a moderate caffeine boost, especially in larger sizes. Be mindful of added sugars and cream boosting the calorie count. Overall, McDonald’s iced coffee can be part of a balanced diet when consumed in moderation.

McDonald’s Iced Coffee vs Cold Brew

McDonald's Iced Coffee vs Cold Brew

In addition to regular iced coffee, McDonald’s also offers cold brew coffee. What’s the difference, and how do they compare in terms of caffeine content?

What is Cold Brew?

Cold brew coffee is made by steeping ground coffee in cold water for an extended time, usually 12-24 hours. This long steeping time extracts the oils and caffeine from the beans without exposing them to heat.

Some key advantages of cold brew:

  • Smoother, less acidic taste – The cold extraction avoids the bitter oils released by hot water
  • Higher caffeine content – The long steeping time extracts more caffeine from the beans

McDonald’s Cold Brew Method

According to McDonald’s, they make their cold brew by:

  1. Steeping a proprietary roast of beans for 20 hours
  2. Straining the grounds from the concentrated liquid
  3. Diluting with water and ice

This method allows them to extract a smooth, highly caffeinated cold brew coffee concentrate.

Caffeine Content Comparison

Here’s how the caffeine content of McDonald’s cold brew compares:

Beverage Serving Size Caffeine
McDonald’s cold brew 8 fl oz 75mg
McDonald’s iced coffee 8 fl oz 45-50mg

The cold brew has significantly more caffeine – around 50% higher than the iced coffee in the same size. This demonstrates the power of the cold extraction process.

Health Benefits and Risks

The higher caffeine content of cold brew provides enhanced stimulation but also increases the risk of side effects if consumed excessively.

To avoid issues, the FDA recommends limiting cold brew intake to one 8oz serving per day. This provides the benefits of increased focus, alertness, and energy, without going overboard on caffeine.

The Bottom Line

For those seeking a stronger caffeine kick, McDonald’s cold brew is preferable to their regular iced coffee. But be mindful of your intake, as the cold extraction process concentrates the caffeine. Moderation is key to getting the benefits without the drawbacks.

Making McDonald’s-Style Iced Coffee at Home

Want to recreate the McDonald’s iced coffee experience in your own kitchen? Here’s a simple recipe to make a dupe at home:


  • Strong brewed coffee – Use extra grounds or repeat the brew cycle
  • Sugar – To taste
  • Milk or cream – 2% or whole milk works best
  • Ice cubes – Fill a glass with ice
  • Flavored syrup (optional) – Try vanilla, caramel, or mocha


  1. Brew a strong pot of coffee by using 2-3 tablespoons of grounds per cup of water. The double strength mimics McDonald’s.
  2. While hot, stir in sugar to taste until fully dissolved. Start with 1-2 tablespoons.
  3. Fill a tall glass with ice cubes. Top with more ice as needed.
  4. Pour the hot sugared coffee directly over the ice. The ice chills it rapidly for an iced coffee effect.
  5. Add milk, cream, or non-dairy milk to taste. Start with 2-4 tablespoons.
  6. Optional: Drizzle in flavored syrup like caramel, vanilla, or mocha.
  7. Stir well and enjoy your homemade McDonald’s-style iced coffee!

Make a batch in a pitcher to serve over ice all week long. Adjust coffee strength, sweetness, and creaminess to suit your personal preferences.
