Grand Marnier and Cointreau are often mixed up with one another, but the truth is… They aren’t the same! While they’re both bitter orange liqueurs mixed with sweetness and botanicals, they are different styles and typically used for independent cocktails without being interchangeable.

If you’re a total cocktail nerd who’s curious to learn more about the difference between these two top-shelf orange liqueurs, we have a whole series of articles explaining the how they compare to each other in production, flavor profile, and use.
COINTREAU VS GRAND MARNIER
Although these two orange-flavored liqueurs are similar, Grand Marnier is an orange Cognac liqueur made with bitter orange peels. Cointreau shares this key ingredient for its orange flavor but is made from a neutral spirit and a blend of sweet and bitter oranges. It is also unaged, unlike Grand Marnier.

SUBSTITUTING GRAND MARNIER FOR COINTREAU AND VICE VERSA
Every now and then, you may come across a recipe that calls for one, but you only have the other. So what can you do? Can you simply substitute Grand Marnier for Cointreau, for example, even though they aren’t exactly the same?
Grand Marnier, the cognac-based orange liqueur, is heavier and sweeter than Cointreau, so you do have to adjust the recipe a little if you’re going to substitute one for the other.
If you do need to substitute Cointreau for Grand Marnier, consider using slightly more Cointreau (not a lot – maybe an additional 1/8oz per oz). This will add the weight and sweetness that your recipe would otherwise be getting from the Grand Marnier.
In reverse, use slightly less Grand Marnier when substituting for Cointreau, as this will similarly adjust for weight and sweetness as well.

Here are a few other delicious recipes that call for Grand Marnier– no substitutions necessary!
COINTREAU AND GRAND MARNIER IN COCKTAILS
Most classic cocktail recipes– like the Cosmopolitan cocktail and Mai Tai— and are made with Cointreau because it tends to be lighter, less sweet, and more versatile. It’s even likely you may only have Cointreau in your liquor cabinet. So if a recipe calls for the orange Cognac liqueur, Grand Marnier, can you just substitute Cointreau?
Yes, you can, but you’ll need to make a little bit of an adjustment to make up for the lost weight and sweetness. I’ve enlisted our in-house mixologist, Rob Harrah, to give you a few delicious recipes using Cointreau instead of Grand Marnier.

#1: El Presidente with Cointreau
“I have seen this cocktail done both ways – with Grand Marnier and with Cointreau – and it’s really good either way, but very different. With the Grand Marnier, the cocktail is richer and fuller, something I would drink in the winter. However, with the Cointreau, it is lighter with bright flavors but still brings a lot of depth while being something I can drink in the spring or fall.” –Rob Harrah
Ingredients:
- 1 ½ oz White Rum
- ¾ oz Dry Vermouth
- ¼ oz Cointreau
- 2 dashes of Grenadine
Instructions:
1. Add all ingredients to a mixing glass with ice.
2. Use your bar spoon to mix for 10-15 seconds to stir and dilute.
3. Use a Julep strainer (or Hawthorne) to strain your drink into a coupe glass or Martini glass.
4. Garnish with an orange twist or cocktail cherry.

#2: The Dubliner with Cointreau
“This cocktail changed a couple of ways by using Cointreau:
- First, I was able to up the amount of Cointreau used in this cocktail because it is a little lighter in flavor and texture, which made the resulting cocktail lighter, too.”
- It doesn’t have quite as much weight and depth as it traditionally does when made with the Grand Marnier, which can actually be nice in some cocktails; but in this one, it almost feels incomplete in its balance of flavors without it.” –Rob Harrah
Ingredients:
- 2 oz Irish Whiskey
- ¾ oz Cointreau
- ½ oz Sweet Vermouth
- 3 dashes of Orange Bitters
Instructions:
1. Add all ingredients to a mixing glass with ice.
2. Use your bar spoon to mix for 10-15 seconds to stir and dilute.
3. Use a Hawthorne or Julep strainer to strain your drink into a coupe or Nick and Nora glass.
4. Complete with a green maraschino cherry (or an orange peel for garnish).

#3: The Millionaire with Cointreau
“Substituting Cointreau for the traditional Grand Marnier changed this sophisticated drink recipe for the better, in my opinion:
- First, I upped the amount of Cointreau from the traditional ¾ ounce to 1 ounce, once again taking advantage of the lightness. I also brought up the lemon juice from ½ ounce to ¾ ounce, which brought even more brightness and depth to the cocktail, especially when combined with the Cointreau.
- I personally like this version better. It’s lighter, brighter, and more refreshing while still offering bold flavors. The original recipe is still delicious, but I find it to be a little too heavy and lacking in the depth one would expect. To be honest, I relish a cocktail that is light enough for me to enjoy two– The Millionaire with Cointreau is that cocktail; the original Millionaire, regrettably, is not.”
–Rob Harrah
