Granny Smith apples are known for being tart and slightly sour, but are they low in sugar, and does sour mean less sugar?
Surprisingly, a medium-sized granny smith apple contains 16 grams of sugar, but it’s actually less than most other types of apples, especially red ones.
In this article, we’ll help you get the exact data you need by showing you how much sugar there is in a Granny Smith apple (depending on size). You can also work out the sugar content for exact Granny Smith weights by using our calculator.
Granny Smith Apple Sugar Content
The USDA confirms that 100g of raw Granny Smith apple (including the skin) contains 9.59g of sugar, which is equal to 0.0959g per gram of apple.
The Granny Smith apple is typically a smaller variety of apple when compared to larger varieties such as the red delicious or Honeycrisp. You can expect a medium Granny Smith apple to weigh an average of around 167g, and an apple of this size will contain 16g of natural sugars.
The quick reference table below shows the amount of sugar you can expect in a small, medium, or large Granny Smith apple based on average weight.

Did You Know?
One medium Granny Smith apple weighing 167g contains 16g of sugar, which is four teaspoons of sugar (weighing 4g). Although this sounds like a lot of sugar, most of the sugar in apples is fructose, which is found naturally in all fruits.
Are Granny Smith Apples High In Sugar?
All apples are fairly high in natural sugars, which is why we love them so much, but some contain more sugar than others.
Granny Smith apples are a little less sweet than some varieties which shows in the sugar content and is also typical of green apples.
For example, a red fuji apple contains 11.7g of sugar per 100g, compared to a Granny Smith, which contains 9.59g per 100g.
So, if you love apples, but you’re trying to cut down on your sugar intake, choose a small granny smith instead of a large red apple.
