Does Starbucks Soy Milk Have Sugar?

Yes, Starbucks soy milk has sugar, both the kind that’s naturally occurring in all soy milk and from the sweeteners and flavors added by the company.

Moreover, soy milk from Starbucks contains 27 grams of sugar in a 16-ounce serving, which is the size of a Grande.

With that, this is higher than any other plant-based dairy alternative available at Starbucks.

As far as approximate sugar content within its entire menu, Starbucks’s soy milk has the most sugar of all its options and is tied to dairy offerings like whole milk and 2% milk.

Does Starbucks Use Organic Soy Milk?

Starbucks uses organic soy milk to make its drinks. In fact, pro-organic food activist groups use Starbucks’ soy milk as the standard that they would want to be upheld for other offerings.

In 2014, an anti-GMO organization known as GMO Inside began putting pressure on Starbucks to treat its other milk options as the company did its organic soy alternative.

Is Starbucks Soy Milk Healthy?

According to most sources, Starbucks soy milk is the second least healthy option available from the coffeehouse, coming above whole milk.

Further, these sources compare the milk options available at Starbucks by how much sugar and calories they have in an equal size serving, and soy milk has a high amount of both.

That said, to give you a clearer picture of these comparisons, here’s how much sugar is available in the milk options at Starbucks in one tall caffe latte with no flavored syrup or whipped cream:

  • Soy milk: 14 grams
  • Almond milk: 4 grams
  • Coconut milk: 9 grams
  • Oat milk: 11 grams
  • Half and Half: 12 grams
  • Nonfat milk: 14 grams
  • 2% milk: 14 grams
  • Whole milk: 14 grams

As for calories, here’s how much is in the same amount listed above:

  • Soy milk: 150 calories
  • Almond milk: 80 calories
  • Coconut milk: 110 calories
  • Nonfat milk: 100 calories
  • 2% milk: 150 calories
  • Whole milk: 180 calories

As per this data, even though Starbucks’s soy milk has roughly the same amount of sugar as nonfat milk, it has significantly more calories, making it a less healthy option.

Moreover, the soy milk used by Starbucks is the least healthy plant-based dairy alternative both in terms of how much sugar and calories it contains per serving.

Where Does Starbucks Soy Milk Come From?

Several sources, including baristas, say that Starbucks uses soy milk from Silk, a manufacturer that sells to the general public, meaning you can buy it from grocery stores.

According to the reports, Starbucks uses soy milk from Silk but with its own branding, so it’s not obvious.

Further, one Starbucks barista on Reddit said that the company uses Silk vanilla soy milk, which aligns with how I’ve established that the milk it uses has vanilla flavoring.

Silk was founded in 1977 in Boulder, CO, and is a company that focuses on plant-based dairy alternatives, including oat, soy, coconut, and almond milk, as well as yogurts and creamers.

Does Starbucks Have Any Unsweetened Milk Options?

Starbucks has several unsweetened milk options, including almond milk and most dairy offerings.

Starbucks serves oat milk from Oatly, saying that its product is not sweetened, but this claim has been challenged recently.

Currently, soy and coconut milk are the options at Starbucks that are sweetened.

Also, Starbucks soy milk is considered the second least healthy option from the coffeehouse by calories and sugar, second only to whole milk.

Further, Starbucks likely uses Silk vanilla soy milk but in custom branding.

Finally, Starbucks uses organic soy milk, and it’s usually pointed to as the standard that the company needs to follow for its other options by anti-GMO activist groups.
